Needle Roller Bearings

A Needle Roller and Cage Assembly for connecting rod bearings comprises of needle rollers and a cage that guides and hold the rollers on its position. A
connected rod bearing operated under extreme loading and operating conditions required a high, rigidity bearing which is light-weight and have high load rating.

a. Needle Roller and Cage Assembly for Connecting Rod Large End

This product is design to withstand the crank motion involving the simultaneous rotation and revolution on the large end side of the connecting rod. The cage is made of special steel and heat treated. Cage is designed for outer diameter guided system so outer diameter is precision finished to avoid unwanted temperature rise during high speed and heavy shock loads. Along with this, the cage can be surface treated using different non-ferrous metal coatings  to avoid friction due to poor lubrication.

b. Needle Roller and Cage Assembly For Connecting Rod Small End

The small end bearing is designed to withstand high impact loads and high-speed oscillation. Cage is designed for inner diameter guide and guide surface is designed to minimize surface pressure. To reduce the contact pressure on rollers, bearing is designed to incorporate with maximum possible length and small diameter of rollers.

Shell type needle roller bearing comprises of an outer shell ring made from special thin steel, needle rollers and cage. A hardened and ground inner ring/ shaft is used as the raceway. This bearing needs no axial clamping due to easy installation and a press-fit in the housing so it can also be used in application where shell face abutment with the hosing is not possible. The outer ring of shell bearing is so thin that it gets deformed and take the shape of housing in which it is press fitted so dimensional accuracy of both shell bearing as well as housing is important for bearing Performance.

Machined ring type needle roller bearing comprises of an outer ring made by machining, needle rollers and cage to guide the rollers. The outer ring is having high rigidity and easy to install. Machined ring needle roller bearing is suitable for heavy loads and used where high bearing accuracy required.

Thrust roller bearing comprises of needle, a cage that guides and retains the rollers. This bearing can take load in axial direction. Also thrust needle roller and cage assembly has no inner and outer ring, heat treated and finished mounting surface can be used as raceway. These bearings are having high rigidity and high load capacity and best-suited to small spaces.
