Racing-oriented bearing solution from 3RACING

Engineered for competitive setups, the 3RACING Double Metal Shield Bearing 3x7x3 mm balances protection and low drag for drivetrain and wheel-end applications. Ten bearings per pack support routine service intervals during race weekends.

Dual metal shields for contamination control

The two-sided metal shield construction limits particulate ingress while maintaining a low-profile sealing surface suitable for high RPM shafts. This reduces unscheduled maintenance and preserves bearing geometry under continuous load.

Application and chassis integration

Standard 3x7x3 mm dimensions make these bearings straightforward to integrate into common chassis points including wheel hubs, pulleys and idler locations. They provide predictable preload behavior when paired with tight tolerance housings.

Setup and service recommendations

Ensure housing bores are clean and true before press fit. Use a measured amount of light oil compatible with shielded bearings and inspect for play or roughness between events to maintain peak performance.

What clearance should I allow for bearing play?

Aim for minimal axial play while avoiding binding; a sealed metal shield bearing performs best with correctly machined bores and slight shaft endplay as specified by the chassis manual.

How often should bearings be cycled at race events?

Inspect bearings each day of competition and replace if any roughness or increased running temperature is detected; having a 10 pack allows scheduled swaps.

Are these suitable for use with hardened steel shafts?

Yes, the bearings are compatible with hardened shafts provided tolerances match; ensure correct interference fit to avoid premature wear under high torque.
