Custom Angular Contact Ball Bearings

How to choose the right contact angle for an angular contact ball bearing?

When choosing the right contact angle for an angular contact ball bearing, you need to consider several factors, such as the bearing's load capacity, stiffness, operating speed, and application scenarios. Based on the experience of Shanghai Yinin Bearing & Transmission Company, here are some guidelines for choosing the contact angle for an angular contact ball bearing:

Load capacity and load direction:

If the bearing is mainly subjected to axial loads, choosing a larger contact angle (usually 40°) will have better load capacity. Smaller contact angles (such as 15° or 25°) are suitable for applications with smaller axial loads or when radial loads are large.

Working conditions and stiffness requirements:

For applications that require higher stiffness, such as precision machinery or high-precision equipment, a larger contact angle can provide higher stiffness, thereby ensuring the stability and precision of the equipment.

Speed ​​requirements:

Small contact angles (such as 15°) are suitable for high-speed applications because smaller contact angles can reduce friction and heat accumulation, and are suitable for high-speed operation. Larger contact angles increase friction and heat generation, so they may not be suitable for high-speed conditions.

Combination of bearings:

Angular contact ball bearings provided by Shanghai Yinin Bearing & Transmission Company are often used in combination with other types of bearings. When selecting the appropriate contact angle, the fit with other bearings should be taken into account to ensure even load distribution and avoid excessive wear.

Environment and working conditions:

Under special environments (such as high temperature or corrosive environments), a larger contact angle may enhance the stability of the bearing, but it also requires a combination of lubrication and seal design. Shanghai Yinin Bearing & Transmission Company can provide corresponding advice to help select the angular contact ball bearing that best suits specific working conditions.

According to Shanghai Yinin Bearing & Transmission Company's industry experience, the reasonable selection of the contact angle of the angular contact ball bearing can increase the service life and reliability of the bearing, ensuring optimal performance under different loads, speeds and environments.
