Compact Double Metal Shield Bearings

For racers and club drivers who want dependable components, the 3RACING Double Metal Shield Bearing is an effective, no-nonsense part. The 5 x 11 x 4 mm two-pack covers many typical bearing positions and helps keep rotation smooth under varied conditions.

Main Advantages

Metal Shield Protection: Twin metal shields defend against dust and small debris for cleaner operation.
Standard Sizing: 5 x 11 x 4 mm dimensions suit a broad range of RC applications from wheels to small gear shafts.
Reliable Performance: Built to support even rotation and predictable handling characteristics.

Mounting and Upkeep

Press bearings in squarely and confirm free spin before reassembly. Inspect bearings periodically, remove lodged particles, and apply light oil if needed to keep them turning freely.

Are these suitable for high RPM applications?

They handle typical hobby RPM ranges well; for extreme high RPM builds, check bearing spec and balance with appropriate lubricants.

Can I replace sealed bearings with these metal shield versions?

Yes, where the shielded profile and size match, but note metal shields are generally less sealed than solid rubber seals against water.

What's the best way to test a new bearing?

Spin it by hand in the housing to feel for smoothness and listen for rough spots; any binding suggests incorrect fit or contamination.
