where's miniature cylindrical thrust bearings rollers sizes, cylindrical pins supplier? how to buy high super precision cylindrical rollers, cylindrical rolling elements for bearing?

we are specialized in super short cylindrical rollers,such as: D1.5*L1.5, D1.5*L1.2, D1.5*L1.0,D2*L2, D2*L1.5, D2*L1.0 etc. only a few manufacturers can fabricate such short rollers.

the cylindrical rollers, it is meaning the outer surface is substantially straight and parallel to the axi of the roller. the cylindrical rollers are precision parts for bearing. precision cylindrical rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. In addition, they can also be served as precision shafts or as precision locating pins in some applications

we are specialized in offering a wide range of cylindrical rollers in the national as well as international markets. the cylindrical rollers, offered by us, are accessible in different sizes as per the requirement of our valued customers. steel cylindrical rollers are remarkable for their high mechanical strength and long lasting functional life. we are counted among the key industrial cylindrical roller supplier in china. besides, we have also earned wide appreciation as original equipment manufacturer supplier from bearings

cylindrical rollers are used in automotive transmissions, universal joints, front wheel drives, constant velocity joints water pump bearings, roller clutches, rollerized cam lifters, rocker arms, cam rollers, starter drives and as pins and dowels for various applications.
