Single Row Needle Rollers

Larger number of small diameter rollers result in lower load rating and reduced fatigue life.

Gap Seals

These seals are designed to fill the gap between outer ring shoulder and the end ring (see above illustration).This results in substantial frictional and thrust loads on seal surfaces that can lead to rapid wear.

Limited Roller Guidance

Minimal Grease Retention Volume

End-guided needle rollers tend to skew during normal operation. This can result in excessive heat generation, which can lead to deterioration of the already limited grease supply.

The only available area for grease charge is between the rollers. Cam follower life is directly related to effective lubrication. Relubrication of needle roller cam followers is required to maximize life.
