Smooth Running Upgrades for RC Models

For quieter operation and longer service life, the XRAY 930812 MR128ZZ 8x12x3.5mm bearing pair is a straightforward upgrade for many rigs. These bearings are sized for common mounting points and help reduce friction in critical rotating parts.

Engineered Precision and Long Life

Manufactured to strict tolerances, these ball-bearings give a secure fit and consistent spin. They arrive lightly oiled with AeroShell Fluid 12 oil to cut initial break-in friction and protect rolling elements from wear.

Where to Fit Them

Whether used in wheel hubs, differentials, or gearbox shafts, these bearings suit a range of on-road and off-road applications across the hobby. The 8x12x3.5mm dimensions make them a versatile replacement item for many 1/10 scale components.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. 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.

Are these bearings a fit for most 1/10 scale cars?

Yes. The 8x12x3.5mm size is widely used in many 1/10 scale models for hubs and small shafts, making these bearings a common spare part.

How should I service these bearings?

Clean out grit with a solvent, dry thoroughly, and apply a small amount of AeroShell Fluid 12 or a light bearing oil to keep friction low and life extended.

What signs indicate a bearing needs replacing?

Look for rough feel when spinning, increased noise, or excess play. Any of these indicate degraded bearings and you should swap them to avoid damage to neighbouring parts.
