Stainless Steel Drawn Cup Needle Roller Bearing 234353 234-353

Stainless Steel Drawn Cup Needle Roller Bearing 234353 234-353

Needle roller bearings have small axial section dimension, good rigidity and capacity to carry high radial loads, which are suitable for limited radial installing when positions. These are widely applied under working situation with swinging shaft and bearing housing. However, needle roller bearing can only carry pure radial load, but, can’t prevent the axial displacement between shaft and bearing housing. In addition, the angle error for inner axle and outer axle is not allowed.

Needle roller bearings have a large carrying capacity and are suitable for supporting structures with limited installation dimensions.
The surface of the journal is hardened as the rolling surface, and the bearing is fitted into the seat hole with a press fit, and there is no need for it to be axially positioned.
The bearing should be injected with an appropriate amount of grease before installation.
Usually, no relubriexcavatorion is required after assembly (BK type bearings are used in the support of the journal without the protruding end, the end face is closed for sealing, and can withstand small axial movement.)

Appliexcavatorion of Needle roller bearing

Depending on the field of activity and appliexcavatorion, needle roller and cage assemblies can be integrated between the rings to strengthen the assembly and ensure the connection between the various mechanical parts.
Therefore, needle roller bearings come in many forms (cages, bushes, bearings with solid rings, combination bearings, needle roller thrust bearings, cam followers, etc.) to meet all technical constraints of the industrial market.
The smallest cross-section in a rolling bearing is Needle roller and cage assemblies provide a very compact solution for appliexcavatorions where space is limited.

High load capacity

Due to the large number of rollers, the needle roller and cage assembly has a high load-carrying capacity.
high stiffness
The needle roller and cage assembly has high stiffness due to the large number of small diameter rollers.
These bearings combine robustness, precision and durability across all industrial markets and are very common, especially in:
car
two wheelerPortable tools (drills, chainsaws)
construction machinery
pump and motor
