Advantages of a Super Precision Angular Contact Ball Bearing
There are many advantages to a super precision angular contact ball bearing. This type of bearing is designed to meet high radial and thrust loads, and is therefore more suited for high-speed applications. Its angular contact configuration guarantees nonstop contact between the ring and balls, lowering vibration and improving accuracy in the final product. It is an ideal solution for prototypes as well as high-volume production.
ABEC7 or P4 precision class
If a ball bearing is required to meet high precision standards, ABEC7 or P4 is the bearing to select. ABEC7 bearings have smaller runout and axial play, making them longer-lasting in high-speed applications. These bearings are designed for machine tools, aerospace, and medical devices. However, if the application does not require very high precision, an ABEC3 bearing will suffice. These bearings are available in limited quantities and can cost up to two-thirds the price of ABEC 1-3 bearings.
Choosing the correct bearing requires a careful analysis of the requirements. The most important factor is the design specifications. If the bearing is not manufactured to strict tolerances, the maximum torque it can handle may be reduced, which can lead to load imbalance at high speeds and reduced life. Bearings with higher tolerances will have higher performance and longer life, but will be more expensive.
25deg contact angle
A super precision angular contact ball bearing with a 25deg contact angle is ideally suited for applications requiring high axial rigidity and load carrying capacity. It is constructed with ceramic balls that are harder than steel balls, which minimizes centrifugal forces. The 25deg contact angle of this type of bearing allows it to run faster than comparable all-steel bearings.
Super precision angular contact ball bearings from SKF are available in diameters ranging from 6mm to 360mm. The bearing's wide variety of specifications means that it can be incorporated into virtually any machine tool application. The 718 (SEA) series is a great choice for high-speed applications. The bearing's tolerance class allows it to accommodate high speeds and low runout. Additionally, it features an extremely compact cross section, allowing it to be easily mounted.
NSK range of angular contact ball bearings
NSK offers a comprehensive range of super precision angular contact ball (ACB) bearings that can accommodate large radial and axial loads. These bearings are often used in pairs, triplex, and quadruplex sets, and they feature a wide range of features and benefits. High Grade Balls, for example, offer smooth operation at high speeds, and Super Finished Raceways help to reduce noise and improve lubricant distribution.
NSK offers a range of Super Precision Angular Contact Ball Bearings in various sizes, shapes, and types. These bearings feature deep grooves, PTFE seals, and ultra-high precision. The D-design bearings can accommodate heavy loads and operate at high speeds in moderate temperatures. They are also a bit more expensive than other bearings, so you should consider their price before purchasing one.
SKF super-precision angular contact ball bearings
SKF super precision angular contact bearings are available for shaft diameters of 6 to 360 mm. These bearings are designed to offer high precision and high energy efficiency. Their high speed capability and low runout make them ideal for high-speed applications. They are also available worldwide, so you can find one that meets your specific needs.
These bearings are designed for axial and radial loads at the same time. The larger the contact angle, the higher the axial load carrying capacity. The combined load is transmitted along the line perpendicular to the bearing axis.
