Technical Notes on 3RACING 3RB-R155-ZZ/2

For competitive tuners, the 3RACING Double Metal Shield Bearings (5/32 x 5/16 x 1/8) offer consistent rotational behaviour and contamination resistance. Their shielded construction reduces ingress while preserving predictable friction characteristics for setup tuning.

Shielding and Service Considerations

Double metal shields protect the inner race from particulate ingress while keeping maintenance intervals reasonable. For race use, inspect bearings regularly and replace if any increase in friction or axial play is observed.

Installation and Fitment Guidance

Ensure the receiving bore is true and use a driver that bears on the outer race when pressing in the bearing to avoid inner race damage. The precise 5/32 x 5/16 x 1/8 dimensions make these bearings suitable for many axle and hub journals used in tuning environments.

What inspection checks should be part of race prep?

Check for smooth rotation, absence of axial play and intact shields. Replace bearings showing roughness or looseness to maintain consistent lap times.

How should I press these bearings into alloy carriers?

Use a press or driver that contacts the outer race only, and support the carrier evenly to avoid distortion of the bore during installation.

Are these bearings suitable for high load sprint classes?

They perform well under typical sprint loads found in wheel and gearbox applications, but validate against your class rules and load cases for sustained high load scenarios.
