Technical bearing upgrade for Mini-Z AWD

This ball bearing set is an engineered replacement for Kyosho Mini-Z AWD drivetrain locations, identified as AWD-22. It is specified to reduce friction compared with plain bushings and restore predictable rotational characteristics in compact AWD assemblies.

The kit targets consistent hub rotation and reduced energy loss within Mini-Z AWD drivetrains. Typical application is replacing worn sliding bearings in hubs and carriers to recover free-running behaviour and improve drivetrain efficiency for competitive tuning work.

Service recommendations for technicians: extract original sliding elements, press-fit the new bearings ensuring full seating and correct orientation, then verify radial and axial clearances. Maintain cleanliness around bearing seats and apply minimal lubrication only when required to prevent contamination and maintain bearing life.

Compatibility checks to perform

Measure hub bore diameter, carrier thickness and overall stack height against the bearing dimensions before fitment; this ensures correct seating and prevents preload or binding issues.

Recommended lubrication practice

Use a light, low-viscosity oil sparingly to preserve rolling action while minimising dust attraction; avoid heavy greases that can degrade performance at high RPM in micro drivetrains.

Service intervals and inspection

Inspect bearings after periodic race sessions for play or roughness, check for contamination in seals, and replace bearings showing wear to maintain consistent drivetrain behaviour.
