Advantages of Stainless Steel Castings
Stainless steel investment castings are used across a wide range of industry sectors for the following reasons:
- Excellent Corrosion Resistance: Chromium is used as an alloying element in stainless steel which helps improve its anti-corrosive properties. Unlike carbon and alloy steel, stainless steel castings require little or no additional surface finishing. This 1 reason why stainless steel investment cast parts are used in industrial components such as valves, pumps, and other parts where corrosion resistance is critical.
- Exceptional Visual Quality: Grade A visual appearance is possible for investment cast parts that require high visual quality.
- Surface Finishes: 120 RMS or better is easily achieve.
- Close Tolerances: ±.005 inch per inch tolerance levels can be achieved
- Near Net Shape Parts: Avoid long run time machine parts using near net investment cast parts.
Production Process
- Creating the “pattern”(i.e. a replica) of the part that’s to be cast by injecting wax into a die. This process is also used for die casting. Usually, the pattern is created as 1 piece.
- Compiling potentially several wax patterns into a completed assembly known as a gating system or “tree”. This form allows molten metal to flow into the CZPT cavity at a later stage.
- Immersing the assembly in high-grade ceramic slurry(known as the investment stage).
- Building up an additional coating of coarse ceramic particles up to 10mm thick while the assembly is still wet.
- Melting the wax from the dry CZPT to leave a thin-walled and hollow ceramic shell.
- Firing the moulds to remove any last vestiges of wax and add durability to the final mould. This can necessitate temperatures of 1000°C.
- Pouring molten metal within the still-heated moulds. A heated CZPT is used to instil better dimensional accuracy, with tolerances of as low as .076mm enabled.
- Breaking or cutting the cooled shell mould open to reveal the casting.
- Cutting each pattern off the tree
- Finishing the final part using fettling, grinding, sandblasting, heat treatment and other testing or surface finishing processe.

Types of Ball Bearings
There are several types of ball bearings: Double-row angular contact, Four-point contact, Self-aligning, and Ceramic hybrid. Here’s a brief description of each. For more information, read our article about Double-row angular contact ball bearings. You’ll be better informed about how they’re made. Also, learn about how the cages that hold the balls in place are secured with rivets.
Double-row, angular-contact bearing
Double-row, angular-contact ball bearings are similar in their contact surfaces in 1 direction, and the 2 pairs of bearings are installed axially opposite to 1 another. This design allows them to support combined loads in axial and radial directions. These types of bearings are used for high-precision, high-speed applications. They can be used in everything from turbines to dentistry equipment. Double-row, angular-contact bearings are available at Grainger, as are single-row versions.
Double-row, angular-contact ball bearings are a popular option for applications where high precision and high speed are required. The design features of these bearings are ideal for applications with axial space restrictions. In contrast, they are smaller than 2 single-row angular-contact bearings and are available in steel, polyamide, or brass cages. Whether you need a cage for high speed or hard operating conditions is up to you. If you are unsure about the right cage for your application, contact Schaeffler.
Single-row angular-contact ball bearings are the most common type of bearings. Double-row bearings are also available with a shielded outer ring, which protects the balls inside the bearing from external contaminants. Because these double-row bearings are a good choice for applications requiring high performance, they are often the most affordable option. They offer similar performance as single-row bearings but are much more rigid.
Preloading is a key performance characteristic for double-row angular-contact ball bearings. Preloading can decrease the service life of double-row angular-contact ball bearings by up to 380 percent. Alternatively, you can preload double-row angular-contact ball bearings by placing spacers between their outer rings. Good double-row angular-contact bearing installation will increase working accuracy and bearing life.
Four-point contact ball bearing
The Four Point Contact Ball Bearing Market can be segmented into 3 types: 35 Degree, 45 Degree, and Other. The 35 Degree segment is expected to witness the fastest growth over the next few years, owing to its increased operational speed and competence in axial and radial axis load handling. Other types of four-point contact ball bearings include the Miniature and Deep Groove varieties. These are widely used in automobiles, aerospace, and other industries.
These bearings are designed for oil-free screw compressors, and they feature an outer-ring guided brass cage to reduce friction and increase running accuracy. In addition, they have lower maintenance costs compared to conventional bearings. However, they have a higher mean roughness value than their counterparts. High-speed operations require high-speed bearings that can withstand fast speed changes. This is because of the higher friction rate, which results from four-point contact.
The Four-Point Contact Ball Bearing is a highly versatile product, as it can handle radial, thrust, and moment loads. Because of this, it is often the first choice for slow to moderate-speed applications. This design also has a simplified assembly process, requiring only a single double-half-turn to install. It is the first choice of many automotive OEMs because it is extremely efficient. If you want a ball bearing with these benefits, you should contact a local bearing company.
The Four-Point Contact Ball Bearing Market will continue to grow despite a tough economy and volatile trade conditions. Demand for automotive and aerospace components is expected to grow alongside a variety of technological advancements. Meanwhile, demand for energy-efficient products will continue to increase with changes in trade policy, an imbalance in the supply-side ecosystem, and geopolitical risk. And while all these factors will continue to drive the market growth, a few challenges are worth considering.
The Four-Point Contact Bearing is designed with the same basic structure as its two-point counterpart. In a four-point contact ball bearing, 1 ball can have 4 distinct points of contact with 2 rings. Two of these contact points may be in diagonal position. The 2 remaining contact points change position and accommodate radial loads. Consequently, the Four-Point Contact Bearing is more flexible and robust than its two-point counterparts.
Self-aligning ball bearing
The self-aligning ball bearing is an incredibly useful tool in many industries. This type of bearing has a sealing lip that makes contact with a smooth chamfer on the inner ring. Because of the self-aligning nature of these bearings, they are not prone to misalignment. They can withstand temperatures ranging from -30°C to 120°C and should not be heated prior to installation.
A self-aligning ball bearing is an elastomer-based spherical-shaped bearing with 2 rows of rolling elements. These bearings can accommodate large radial loads, and their outer ring raceway is curved to provide a spherical effect. The inner ring, or cage, can be either cylindrical or conical. The inner diameter of a self-aligning ball bearing is normally cylindrical, but some are conical. They typically have 3 oil holes.
When choosing a self-aligning ball bearing, look for a model with a large enough bearing diameter to accommodate the shaft’s bending. Self-aligning bearings may also be interchangeable with standard ball bearing assemblies. You can find individual values in manufacturer catalogues. These bearings are useful in limited applications, although they are not necessarily ideal for everything. For example, in applications where combined loads are the main concern, self-aligning ball bearings should only be used if the application requires minimal misalignment.
A self-aligning ball bearing is a highly-efficient, energy-efficient solution for a variety of applications. It is a simple, low-maintenance solution that makes your life easier. Its unique outer raceway allows restraining springs to absorb the deflection that is common in other bearings. The result is a cooler, smoother running vehicle. It also helps prevent misalignment, which makes it ideal for use in many applications.
The SKF self-aligning ball bearing is an excellent choice for applications involving heavy deflection of the shaft. They are the lowest-friction bearing available. Their steel plate reinforced seals prevent them from separating from the shaft during operation. They are also resistant to oil, making them the perfect solution for high-speed applications. In addition to this, they are designed to work in a wide range of temperatures.
Ceramic hybrid ball bearing
A hybrid ball bearing made from a combination of steel and ceramics is a good option for high-speed applications requiring electrical isolation. This combination offers an extended lifespan and minimal electrical corrosion or seizure risk. In addition, the hybrid ball bearings have less friction than steel bearings and can operate at low speeds. To learn more about this hybrid type of bearing, continue reading. We’ll also discuss how it can help your application.
Full ceramic balls are generally harder than steel, but they do have lower density, meaning they’re not subject to the same high centrifugal forces as steel balls. These benefits make ceramic ball bearings much more durable, with long lifespans. Both full and hybrid ceramic ball bearings are available from CZPT. Read on to learn more about each type. Here’s a look at some of the benefits of each. You’ll be pleasantly surprised.
A hybrid ball bearing consists of steel inner and outer rings and a ceramic ball. It can withstand high speeds and loads, but it’s also designed to operate in extreme temperatures. This hybrid ball bearing also requires minimal lubrication and is suitable for a variety of applications. Because of its unique characteristics, hybrid bearings are lightweight and hard, and they spin faster than steel balls. But how do you choose the right 1 for your application?
A ceramic ball bearing is better than a steel 1 for many applications. Its greater speed capability and lower friction allow it to operate at higher speeds than steel balls. It is also less sensitive to fluctuations in lubrication conditions than steel balls. They also tend to be cheaper, so it makes sense to invest in one. It’s worth your while. They last longer, and they don’t require a run-in period.
A hybrid ball bearing is the best choice for electric spindles with high speed and heavy loads. A hybrid ceramic ball bearing has the advantage of low heat and high stiffness, and can operate at high speeds and loads. This thesis explores the dynamic characteristics of a hybrid ceramic ball bearing, including analysis calculations and experiment verification. The results provide reliable data and lay the foundation for professional spindle optimum design tests. It is a worthy addition to any machine shop.
