Race-Grade Bearing Choice

The 3RACING Double Metal Shield Bearing in 6x12x4 mm format is a straightforward upgrade for racers wanting dependable rolling efficiency. These bearings are intended to reduce parasitic drag while maintaining basic protection against contaminants.

Shielded Bearing Advantages for Competitive Use

Double metal shields help limit ingress without significantly increasing drag, making them a good option for tuned drivetrains where low friction is important. They suit applications where ease of replacement and predictable behavior matter during setup changes.

Installation and Tuning Fitment

The common 6x12x4 mm size allows quick swapping into many hub and gearbox locations. Installers should check shaft tolerances and clearances as part of a standard race setup to ensure optimal bearing preload and alignment.

Which surfaces suit these shielded bearings?

They perform well on clean track surfaces and prepared club tracks; for extremely dirty or wet conditions a sealed rubber shield may be preferable.

What lubricant is recommended for race use?

A light bearing oil or low-viscosity bearing lubricant is commonly used to reduce drag while maintaining protection; select a product consistent with your setup and track conditions.

Are these suitable for high RPM brushless motors?

For typical hobby high RPM applications these shielded bearings are acceptable, but monitor for heat and wear in sustained extreme RPM environments and replace as required.
