Sturdy 3Racing metal shield bearings for dependable running

Wheel-to-shaft friction is reduced when using the 3Racing 4x7x2.5mm Double Metal Shield Bearings, which are produced to consistent tolerances for predictable handling. These bearings help keep drive components operating smoothly over sessions.

Protection and performance

The metal shield construction offers a balance of protection and low rolling resistance, keeping contaminants at bay without noticeably increasing drag. That balance makes them suitable for club racing and weekend bashing.

Versatile fit across models

The compact 4x7x2.5mm dimensions fit many small hubs, gearbox outputs, and steering assemblies, so they are a useful spare on race day or in the workshop.

Are these bearings sealed for dusty conditions?

The double metal shields provide good defence against dust and debris, though heavy mud will still require cleaning and inspection.

What does the 3RB-MR74-ZZ/10 code indicate?

That code refers to the 10-piece pack of 4x7x2.5mm double metal shield bearings sold under the 3Racing part number.

Should I replace all bearings at once?

It is good practice to replace bearings in matched locations to keep handling consistent; replacing worn bearings in groups reduces imbalance.
