Long-Life Double Shield Design

If you want dependable, low-drag components in your model, the 3RACING Double Metal Shield Bearing is a solid choice. The pair of 5 x 11 x 4 mm bearings is sized for common applications and built to keep moving parts turning smoothly.

Key Benefits

Metal Shield Protection: Shields cut down on grit ingress to extend usable life between services.
Standard Sizing: The 5 x 11 x 4 mm footprint fits many hub, gearbox, and servo link locations.
Reliable Performance: Designed for consistent rotation to support predictable model responses.

Installation Advice

Clean the housing and press the bearings straight into place to avoid misalignment. Check spin after installation and schedule light inspections to remove trapped debris.

Will these fit small scale rock crawlers?

They can be used where the 5 x 11 x 4 mm size is specified, but confirm bore and shaft dimensions before swapping into crawler axles.

Do the metal shields require lubrication?

Shields keep contaminants out but you may apply a small amount of light oil if rotation becomes noisy; shields will retain most lubricants.

Can these bearings be used in gearboxes?

Yes, they are suitable for many gearbox shafts as long as the internal clearance and fit are correct for your specific transmission design.
