74xx angular contact ball bearing
Description
Series 7400 single row angular contact ball bearings are the angular contact versions of the 6400 series bearings. We use them when, in addition to the radial load, the bearing must also withstand an axial load. The bearing consists of a four-digit identification number, the first two of which are always "74". The second pair of digits can range from 00 (in theory) to 99 and shows the nominal diameter (shaft size) of the bearing's inner ring.
Other features of the 7400 series bearings are identified by signs or suffixes. The most common prefixes or suffixes of the 7400 series bearings: SS=stainless steel material, TN=polyamide basket, A=contact angle 25-30 degrees, B=contact angle 40 degrees, C=contact angle 15 degrees, 2RS=plastic dust cover .
