Technical Overview of JR-CBR-TM-057 Bearings

The Jazrider JR-CBR-TM-057 Metal Shielded RC Ball Bearing Set provides a pack of 12 bearings, each 5 x 11 x 4mm, intended as a direct upgrade for Tamiya items such as The Frog and Subaru Brat. The shielded design reduces ingress of dust while maintaining low rolling friction for drivetrain and hub applications.

Engineering and Compatibility Notes

These bearings are manufactured to common dimensional tolerances for 5 x 11 x 4mm bearings, enabling straightforward replacement of worn components. They are suitable for wheel hubs, gearbox outputs and other rotating assemblies where compact, shielded bearings are required.

Installation Best Practices

Use a proper bearing press or a soft drift to install bearings without deforming the outer race or shield. Ensure mating bores are clean and free of burrs. For longevity, inspect bearings periodically and apply minimal bearing oil if increased smoothness is needed.

What tolerances should I expect from these bearings?

These are general-purpose shielded bearings produced to standard hobby-grade tolerances suitable for typical RC drivetrain loads. For precision racing applications review bearing runout prior to use.

Are the shields removable for cleaning?

The metal shields are designed to provide protection in service and are not intended for routine removal. If deep cleaning is required, follow careful disassembly procedures to avoid damaging the shield or race.

Which locations on a Tamiya kit benefit most from these bearings?

Priority locations include wheel hubs, differential outputs and gearbox shafts where reducing friction and axial play improves efficiency and component life.
