Depending on the usage conditions, if rotational load*2 is exerted on the bearing, a slip phenomenon called creep can occur between the housing and the bearing, which results in wear that can reduce the life of the bearing. In 2007, NSK launched its Creep-Free™ series of bearings of an inner diameter (ID) of 45 mm or smaller. This series has been very well received by our customers. In ...

1 "ABEC" is applied for ball bearings and "RBEC" for roller bearings. Notes 1: JIS B 1514, ISO 492 and 199, and DIN 620 have the same specification level. 2: The tolerance and allowance of JIS B 1514 are a little different from those of ABMA standards.
Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
