Sealed Bearings for Consistent Performance

The 3RACING Double Rubber Seals Bearing 4x10x4 mm is aimed at hobbyists who need dependable rotation with reduced contamination risk. The pair fits many small-scale RC applications for repair and upkeep.

Double Seal Benefits

By keeping dust and fine debris away from the races, the dual rubber seals help bearings retain smooth spin and reduce the need for frequent servicing between sessions.

Size and Use Cases

With a compact 4x10x4 mm form factor, these bearings are suitable for wheel hubs, small gearboxes, and other tight spots where a sealed bearing improves component life.

How do I check if they fit my hubs?

Measure the hub bore and axle journal; if the dimensions match 4x10x4 mm bearing specs these 3RACING items will fit correctly.

Are sealed bearings serviceable?

Sealed bearings are not designed for easy servicing, but you can refresh lubrication if you carefully remove seals; often replacement is faster and more reliable.

Do these bearings suit high RPM parts?

They work at moderate speeds found in many hobby gearboxes and wheel hubs; for extreme RPMs check your model requirements and choose a bearing rated for those loads.

How often should I replace them?

Replacement frequency depends on conditions and usage. Inspect bearings after heavy runs and replace if you notice roughness or play to keep drivetrains reliable.
