single row spherical roller bearing have one row of spherical roller,spherical track of the outer ring and one track of the inner ring,its also name barrel roller bearing by FAG,NSK,NTN,EASIER have single row spherical roller bearing production ,this kind of bearing is similar with double row but only one row self-aligning rollers,it designed for supporting heavy and combined loads,so it is particularly suitable very high radial shock type loads occur and misalignments must be compensated,
Barrel roller bearings comprise solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore and barrel rollers with cages. The bearings cannot be dismantled. This structure also guarantees resistance to errors of alignment and shaft deflections. Spherical roller bearings, when operated normally with rotating inner ring can tilt (to compensate alignment deviations) by 0,5o from the central position. At smaller load even by 2o, if the surrounding construction allows that. When the outer ring rotates the angular displacement capability is smaller. Standard spherical roller bearings are heat-stabilized to the temperature above 120oC. For smaller bearings the limiting temperature is usually at 150oC and for bigger usually at 200oC. Spherical roller bearings with a solid polyamide cage are adapted for continuous operation in temperatures not higher than 100oC.
Single row spherical roller bearing have brass cage,nylon cage design,XRB can supply FAG,NSK,NTN,EASIER single row self-aligning roller bearing. the outer dimension from 47mm to 480mm,please contact our sales team if you need high quality single row spherical roller bearings.
