MINIATURE AND EXTRA SMALL BEARINGS

The Miniature and Extra Small Bearings are widely used in application for smaller dimensions and lesser load capacity.

• Open type
• Shielded type
• Shielded type with snap ring

These bearings can be classified as follows:

• Angular contact ball bearing
• Four-point contact ball Bearing
• Double row angular contact ball bearing

Angular contact ball bearings are non-separable bearings which have a certain contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings.

Four-point angular contact ball bearings have a contact angle of 30° and inner rings which are separated in half. These bearings are capable of accommodating radial loads, axial loads in either direction, and have a high capacity for momentary loads as well.

The structure of double row angular contact ball bearings is designed by arranging two single row angular contact bearings back-to-back in duplex (DB) to form one united bearing with a contact angle of 25°.
