Whether you are refreshing a running gear or fitting spares, the 3RACING Double Metal Shield Bearing 4x8x3mm pack provides dependable service. These bearings are sized for common small-scale RC mounting points and aim to improve smoothness.
Use these bearings in wheel hubs, motor mounts and small gear trains to reduce drag and help maintain consistent steering and throttle feel. Their compact profile suits tight assemblies.
The twin metal shields limit ingress of grit while allowing bearings to run freely, which helps preserve life span and reduce maintenance frequency for regular running sessions.
As a general replacement part, these bearings are compatible with many kits and aftermarket parts, making them a useful item for pit crews and weekend builders.
