Smoother drivetrain performance with Tamiya 42370 - 630 bearings

If you want to reduce rolling resistance and improve bearing life, the Tamiya 42370 - 630 Sealed Ball Bearings are a straightforward upgrade. These rubber-sealed bearings give a precise fit and offer smoother rotation across a range of RC car components.

Advantages of rubber-sealed bearings

Compared with fixed metal-sealed types, rubber-sealed bearings are easier to service. The seals allow you to access the internals for cleaning and lubrication, and the low-friction oil inside helps keep rotation smooth while lowering wear during regular use.

Where to fit these bearings

• Versatile use: Ideal for belt tensioners on touring cars and other small rotating mounts.
• Better rolling efficiency: Swapping plastic or plain bushings for these bearings reduces friction and improves responsiveness.
• Simple upkeep: Rubber seals let you clean and relube the bearings without special tools.
