Long Life 3Racing Flanged Bearings

The 3Racing Double Metal Shield Flanged Bearing 4x7x2.5 mm is a compact upgrade for RC builders wanting smoother wheel and shaft rotation. Supplied as a pair, these bearings are engineered to lower friction and minimise wear so your model keeps running consistently under normal hobby use.

Benefits of the Double Metal Shield

These 3Racing flanged bearings use double metal shields to reduce ingress of dust and small debris that can harm bearing life. That extra protection makes them a good choice for running on mixed surfaces where contamination is a concern.

Fitting and Care Advice

Fit the 3Racing flanged bearings squarely into the housing to prevent misalignment and premature wear. Periodic cleaning and a light application of suitable bearing oil will maintain smooth rotation and extend service intervals.

Are these 4x7x2.5mm bearings a direct swap for wheel hubs?

They fit many hubs that accept 4x7x2.5 mm bearings, but check your hub bore and flange clearance before installing to ensure a correct press fit.

What lubricant should I use with these bearings?

Use a light bearing oil or thin synthetic lubricant for low resistance; heavier greases can add drag and reduce top speed on small bearings.

How do I tell when they need replacing?

Check for roughness, play, or increased heat after runs; any grinding or binding indicates it is time to replace the bearings.
