3Racing 3RB-MR74-ZZ/10 4x7x2.5mm Double Metal Shield Bearings Pack  [3RB-MR74-ZZ/10]

Long lasting protection from 3Racing shield bearings

RC hobbyists who want smoother drivetrain response will find the 3Racing 4x7x2.5mm Double Metal Shield Bearings useful for reducing friction and slowing wear. Manufactured to consistent tolerances, these bearings help wheels and shafts turn with less resistance for cleaner power delivery.

Benefits of the 3Racing design

The double metal shields offer solid defence against grit and airborne debris while keeping rolling resistance low, so bearings stay serviceable longer between maintenance intervals. These parts are suitable for regular track use and spirited club runs.

Compatibility and typical uses

With a compact 4x7x2.5mm form factor, these bearings suit a variety of small shafts and hub assemblies across many touring, buggy, and pan car models. Carry a few spares to simplify repairs and setups on meet days.
