Product Function

Excellent Quality and Superb Value

These NPB RC bearings use 1 x rubber seal and 1 x metal shield.

This is to be installed with the rubber seal facing the dirt. The metal shield offers less resistance therefore reducing load on the bearing giving a higher max RPM.

Over time these bearings have been refined to provide the best possible type of rubber seal, and additionally the lubricant package has been refined to offer less resistance, more protection and longer life.

Commonly used as Clutch Bell bearings in 1/8th Nitro Buggy/Truggy, also found in 1/10th on and off road models.
