313xx tapered roller bearing
Description
Series 31300 tapered roller bearings are stronger versions of angular contact ball bearings. We use them when the bearing has to withstand high axial and radial loads. The outer ring of tapered roller bearings is not fixed to the basket and the inner ring. The bearing has a five-digit identification number, the first three digits of which are "313". The last 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 31300 series bearings are identified by signs or suffixes. The most common prefixes or suffixes of the 31300 series bearings: SS=stainless steel, TN=polyamide basket. You can find more information in the catalogs by clicking on the DOWNLOADABLE DOCUMENTS tab.
