High performance and low price needle roller bearing

Needle roller bearing is a roller bearing with cylindrical roller, relative to its diameter, the roller is thin and long.
This roller is called a needle roller.
Despite having a smaller cross section, the bearing still has a higher load-bearing capacity. The needle roller bearing is equipped with thin and long rollers, so the radial structure is compact. Its inner diameter and load capacity are the same as other types of bearings, and the outer diameter is the minimum.
Needle roller bearing is divided into: (1), enclosed stamping outer ring needle roller bearings (2), inner ring needle roller bearings (3) and has no inner ring needle roller bearing/without inner ring cage needle roller bearings (4), with and without cage cage filled with needle roller bearing (5) the SKF also can supply various types of needle roller bearing, 1, 2 needle cage components, no guard the needle roller bearing 3, can make 4, combined needle roller/ball bearing 5, combination needle/thrust ball bearing 6, combined needle roller/roller thrust bearing.
