Racing-Oriented Double Shield Bearings

The 3RACING Double Metal Shield Bearing in 3 x 7 x 3 mm size provides a compact solution for reducing contamination-related variability in drive systems. The dual metal shields focus on maintaining clean raceways under typical track conditions.

Application for Tuned Setups

These bearings suit competitive-minded builders tuning gear mesh and wheel runout. By lowering rolling resistance and excluding debris, they help sustain predictable drivetrain response during a race program.

Professional Fitment Tips

For best results, verify press fit tolerances and ensure the bore is concentric to the shaft. Use a straight press tool and minimal lubrication to avoid changes in bearing preload and to keep drag consistent.

What lubrication is recommended for race use?

A thin bearing oil or light synthetic oil is preferred to minimise drag while providing adequate protection; avoid heavy greases that alter bearing drag and response.

How do these bearings affect tuning consistency?

By limiting debris ingress and stabilising rolling resistance, these bearings help keep drivetrain behaviour more consistent lap to lap, aiding repeatable setup adjustments.

Recommended inspection interval under race conditions?

Check bearings between heats or practice runs; replace if you detect any roughness, increased drag, or play to maintain competitive reliability.
