Performance-Focused Shielded Bearing

The 3Racing Double Metal Shield Bearing, sized 1/4 x 1/2 x 3/16 inches, is engineered for reduced drag in precision RC applications. These bearings support consistent rotational behavior under load, aiding predictable handling at race pace.

Shielded Protection for Durable Operation

Dual metal shields provide a barrier against typical track contaminants while maintaining a compact profile. This balance preserves bearing geometry and service life without significant added friction.

Application and Tuning Notes

These 3Racing bearings suit wheel hubs, gearbox shafts, and other short-span rotating points where low friction and reliability support lap time consistency. When optimising for speed, pair with light lubrication and confirm proper preload to avoid side loading.

How do shields affect high RPM stability?

Metal shields offer modest drag but keep debris out; for sustained high RPM runs balance lubrication and shield condition to maintain stability.

Recommended lubrication for race setups?

Use a light bearing oil or low-viscosity racing lubricant to minimise drag while preserving protection; avoid heavy grease in precision locations.

Any fitment advice for gearbox shafts?

Ensure the housing bore is concentric and apply even press fit. Excessive radial load or misalignment will reduce bearing life and degrade performance.
