The SB200 insert bearing is a cylindrical spherical surface bearing. Its imperial system products have specific representations, such as SB204 - 12. Here, 12 represents the inner diameter size. The formula for calculating the inner diameter size of imperial system products is (12/16) * 25.4. The material of this series of bearings is usually high-carbon chromium bearing steel (fully quenched type) (GCr15), and its working principle is rolling.

Features of fit with shaft:

Insert ball bearings are generally not used alone. The SB200 series also needs to be installed inside the bearing housing for complete assembly. The Insert bearing housings come in various shapes, so after overall fitting, they are suitable for use in various structural positions. The standard tolerance is internal plus external minus, and the inner diameter adopts the plus tolerance, thus ensuring the lightness during the fit with the shaft.

Bearing Application

Insert ball bearings are particularly suitable for scenarios where simplicity of equipment and components is required. For instance, they are used in agricultural machinery, transportation systems, or construction machinery, mainly to bear combined radial and axial loads, with radial loads being the dominant component. Generally, they are not suitable for bearing axial loads alone.
