33xx angular contact ball bearing DOUBLE ROW
Description
Series 3300 Double Row Angular Thrust Ball Bearings are the Angular Thrust Version of Series 4300 Bearings. We use them when, in addition to the radial load, the bearing must also withstand an axial load. The bearing has a four-digit identification number, the first two of which are "33" or "53". Bearings marked 3301 and 5301 are identical. 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 3300 series bearings are identified by prefixes or suffixes. The most common symbols of the 3300 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 .
