Small 5x8x2.5mm bearing ideal for tight-clearance builds

This Yokomo YOKBB850P 5x8x2.5mm Super Precision Bearing is a compact metal ball bearing suited to RC-scale rotating parts. The compact dimensions work well in setups where low profile and reliable rolling are priorities, such as lightweight touring and micro classes.

Use cases include replacement in idler pulleys, compact gearbox outputs, and other small rotating supports where reduced friction improves throttle response and reduces heat build-up. The bearing's close tolerances aid consistency when adjusting gearing or motor selection.

Assembly advice: press the bearing squarely into its bore contacting the outer race only, verify shaft runout after installation, and perform light lubrication when breaking in or before dusty outdoor runs.

Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will switching to this bearing lower drivetrain friction?

Yes, a precision bearing with tight tolerances can reduce friction compared to worn or lower-grade bearings, improving efficiency and slightly boosting top speed or throttle response.

Are there benefits to using this size in micro setups?

The low profile of a 5x8x2.5mm unit is well suited to cramped layouts where space is limited, helping preserve clearance while providing reliable rotation.

How often should I service these bearings when tuning frequently?

For frequent tuning runs check bearings after each session; clean and relube as needed. High-RPM tests call for lighter oil and more frequent inspection.

Is this bearing suitable for both wheels and motor mounts?

It is suitable for many small wheel hub and motor mount positions where the 5x8x2.5mm dimension is specified, provided fitment and load conditions are respected.
