Performance oriented sealed bearings from 3RACING

The 3RACING Double Rubber Seals Bearing 5/32 x 5/16 x 1/8 is specified for racers seeking predictable bearing behaviour under load. Ten bearings are provided for multiple mounting points or spares during race weekends.

Engineering benefits for racing use

Dual rubber seals reduce particulate ingress while preserving internal grease film, which helps stabilise friction levels lap after lap. This results in steadier drivetrain response and fewer pit stops to replace bearings.

Common race applications

These bearings suit hubs, wheel carriers and gearbox positions on 1/10 scale kits where sealed protection reduces service interventions between heats. They are a cost effective upgrade for teams aiming for consistent lap times.

Fitment and workshop tips

Press fit each bearing squarely with a driver that contacts the outer race, inspect for lateral play, and replace any bearing showing roughness. Use a quick inspection routine between runs to catch contamination early.

What race positions benefit most from sealed bearings?

Wheel hubs and idler positions gain most from seal protection since they are exposed to track debris and directly affect lap time consistency.

How should I inspect bearings between heats?

Spin each bearing by hand, listen for roughness, and check for axial play. Replace any bearing that feels gritty to avoid performance degradation.

Are sealed bearings compatible with tuning for lower friction?

Sealed bearings balance protection with low internal drag; for ultimate low friction options consider precision grades but expect more frequent servicing in dirty conditions.
