Roller Follower Bearing STO 17 17X STO17X STO17 Needle Roller Bearing17*40*16mm
Needle Roller Bearings are the roller bearings with cylindrical roller elements, compared with the diameter, the needle roller are both thin and long, so they are called needle roller. Although the section is small, the type of bearings still has the high ablity of load, it specially can be used to the situation of being restricted of the radial space..
Product construction:
Needle roller bearings consist of an inner race (shaft), needle cage, needle rollers and an outer race. The rollers are cylindrical, thin, and long. These bearings are compact because there is less clearance between the diameter of the shaft and that of the bearing. This quality makes them suitable for situations where there is limited radial space.
Special Directions:
Bearing running clearance and inner-cutting roundness should be regulated according to different
conditions.
Machine tolls should be used for press-in fitting or thermal fitting when install the bearing.
Limited by plastic cages(suffixed with TN) and sealing-element material ,operating temperature
is -30℃--+100℃
For general-disposition design of bearings,refer to the relevant recommendation in the applied
technology of roller bearings.
