Drawn Cup
Needle roller bearings with a thin needle roller bearings stamping outer ring. Its main feature is the low sectional height and bear higher load capacity. Mainly used for compact, inexpensive and not as a needle bearing inside the hole cage assembly raceway bearing configuration. Bearings and bearing housings shall install an interference fit. If it can save me axial positioning shoulder, retaining ring, and other functions, then the bearings inside the hole can be made very simple and economical.
Mounted on the shaft end Needle roller bearings have open bilateral and unilateral closed. Drawn cup base closed end surface can withstand small axial guiding force.
Needle roller bearings are generally not attached to the inner ring. In the journal can not be hardened and ground situation, you can use the table listed in the inner ring.
Needle roller bearings hardened steel outer ring and needle roller cage assemblies can not be separated. Lubricant storage free space can be extended to add lubrication interval. Bearings generally use single design. Except wide specification bearings 1522,1622,2030,2538 and 3038 series, which is equipped with two needle roller cage assemblies. Bearing outer ring with lubrication holes. According to user needs, the shaft diameter greater than or equal to all single 7mm Needle roller bearings can be equipped with lubrication holes in the outer ring (code suffix AS1).
Needle roller bearings with seals
The seal can not be installed due to space constraints of the occasion, it can provide an open-ended or closed end Needle roller bearings with seals (3-5). Such equipment bearing polyurethane or synthetic rubber friction seal, wherein the lithium base grease filling good antirust properties, suitable operating temperature -20 to + 100 ℃.
A seal bearing inner ring is wider than the outer ring 1mm, this is the bearing in the machine axis relative to the displacement of the bearing box with a little work but also to ensure good seal and prevent injury bearing contamination. Bearing inner ring lubrication holes are also, according to the needs of the bearing arrangement, the outer or inner supplementary lubrication.

Physical ring
Physical ring needle roller bearing is composed of one or two rings and needle roller set with cage components. Depending on the application, it can be divided into inner ring or without an inner ring of the bearing. Therefore, entities ring needle roller bearings to meet light weight, small footprint, deliver power requirements. Physical ring needle roller bearings with smaller size and higher load carrying capacity.
