RTR can supply roller bearing as followings:

cylindrical roller bearing:
Single-row cylindrical roller bearing
Double-row cylindrical roller bearing
Four-row cylindrical roller bearing
SL Series cylindrical roller bearing
cylindrical bearings are designed to manage heavy radial loads through expertly designed critical dimensions, such as roller and raceway diameter and contact geometry. Our cylindrical bearings range from small to large bores - with up to four rows of rollers - for a wide range of industrial applications.

 taper roller bearing,
Single-row taper roller bearing
Double-row taper roller bearing
Four-row taper roller bearing
Inch taper roller bearing
Tapered bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 bearing combinations - in single, double and four-row configurations. Sizes range from an 8mm (0.31496'') bore to a 2,222.5mm (87.5'') outside diameter. Customized geometries and engineerd surfaces can be applied to these bearings to further enhance performance in demanding applications.

spherical roller bearing,
Spherical roller bearings are double row,self-reraining units comprising solid outer ring with a concave raceway,solid inner rings and barrel rollers with cages.The inner rings with cylindrial or tapered bores.The symmetrical barrel rollers freely align themselves to the concave outer ring raceway.As a result,shaft deflections and mislignments of the bearing seats are compensated
 
thrust roller bearing
 thrust roller bearing is applied to take axaial loads. It has a high load capacity. The housing washer and the shaft washer of it are made of bearing steel. The cage material can be copper base alloy,aluminum alloy,steel.the cylindrical roller thrust bearings made in RTR use copper base alloy as the basic cage material.Aluminum alloy & carbon steel and plastic are also available on the request of the clients.In that case,some special suffix should be appended to the bearing codes to show the difference.
