Solid Collar NA 495 Flat Needle Crossed Single Row Roller Bearing with inner ring
Needle Roller Bearing :
Needle roller bearing is thin and long relative to its diameter,compare with cylindrical roller, such is called needle roller. Despite of the smaller cross-section,
bearing still has a higher load bearing capacity, so it is especially suitable for radial
space restricted applications.
Needle roller:
1. GCr15 bearing steel.
2. Through grinding machine grinding.
3. HRC60-64.
Specification:
1.Needle roller bearing is a cylindrical roller of roller bearings, relative to its diameter, roller is thin and long.This is called needle roller.Although has a small cross-section, bearing still has high load capacity.
2.Needle bearing with fine and long roller, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting results.
3.In order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.
