How to choose Bearing units

Points to check when selecting, with the values for this product (Y-Bearing with Set Screw (YAR/YAT/YARAG)).

  1. 1. Match shaft diameter and dimensional system (metric/inch)

    This product: Shaft diameter d 12~100 mm

    Bearing units are offered in separate metric and inch series, and they are not interchangeable even when their appearance is similar. Listed products cover metric sizes of 3 to 150 mm and inch sizes of 1 to 4 in. First determine the shaft diameter and dimensional system, then select from the corresponding series.

  2. 2. Check the rated load against the operating conditions

    The basic dynamic load rating Cr is used for rolling fatigue life calculations, and the basic static load rating C0r is used for evaluating stationary or shock loads. Listed Cr values range from 7.28 to 793 kN, and there are heavy-load products, such as half-ring types, with increased static load ratings.

  3. 3. Select a specification suited to the operating temperature

    Standard greases and rubber seals deteriorate at high temperatures. High-temperature specifications are available in types with different upper temperature limits; for example, VA201 is rated at 130 to 250°C and VA228 at 260 to 350°C. In addition to the ambient temperature, check the permissible seal temperature and the sealed grease.

  4. 4. Choose the shaft fixing method for the application

    Set-screw type is easy to install but requires control of the tightening torque. The method that fixes the bearing with a tapered bore and adapter sleeve provides a secure connection to the shaft and suits applications with reversing rotation or vibration. Check it together with the recommended shaft tolerance grade.

  5. 5. Verify the permissible rotational speed

    Bearing units have an upper limit on usable rotational speed depending on seal friction and the fixing method. The permissible speeds of listed products range widely from 6 to 12000 r/min, and low-speed heavy-load and high-speed units have very different characteristics. Confirm that the operating speed has sufficient margin.

  6. 6. Allow for shaft tilt during installation

    In the spherical-fit design, the unit can absorb shaft tilt during installation up to a certain angle. However, in structures that allow regreasing, the permissible angle may be smaller. Listed products include an example of 2°. Check the permissible misalignment according to the accuracy of the base or frame.
