Precision Flanged Bearings for Racing Setups

The 3Racing Double Metal Shield Flanged Bearing 4x7x2.5 mm is specified for builders wanting a sealed, low drag bearing option in tight tolerances. Delivered as a two piece set, these bearings are intended to provide consistent rolling resistance and predictable behaviour during tuning.

Shielding and Flange Function in Performance Use

Double metal shields limit particulate ingress while preserving minimal internal clearance, which assists in maintaining bearing geometry under load. The flange provides a reliable axial location that simplifies alignment in hub and gearbox assemblies.

Installation and Service for Tuned Vehicles

Install the bearings using a driver against the outer race to avoid inner race damage and ensure concentric fit. Periodic inspection for endplay and smoothness, plus light lubricant application, will help sustain performance in demanding racing environments.

Expect low running clearance typical of shielded miniature bearings; ensure the housing does not compress the outer race which can increase friction.
They perform well in light to moderate load applications; for heavily loaded gears review bearing ratings and consider larger or specialist bearings where necessary.
A bench press or a correctly sized bearing driver that contacts only the outer race is recommended to avoid inner race or shield distortion during fitting.
