Reliable Rotation with XRAY 930407 Bearings

For tuners and racers seeking consistent wheel and shaft performance, the XRAY 930407 MR74ZZ bearing set provides compact, low-friction components. These are the common 4x7x2.5mm size and shipped as a pair for routine servicing.

Finish and Treatment

The XRAY 930407 MR74ZZ bearings are prepared by degreasing and a light application of AeroShell Fluid 12 to optimise smoothness while maintaining accurate clearances. That careful prep helps reduce early wear and promotes even running.

Use Cases and Maintenance

Ideal for replacement jobs or when building precise drivetrains, these bearings support a variety of moving parts. Regular inspection and appropriate lubrication will keep them performing reliably in both track and club use.
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.

How can I check if a bearing needs replacement?

Feel for roughness or play when you spin the shaft by hand; noise, binding or lateral movement are signs to replace the bearing.

Is AeroShell Fluid 12 necessary to use with these bearings?

The bearings are pre-treated with a light coating of AeroShell Fluid 12 to aid smooth running, but you can relube with an alternative bearing oil if preferred.

Are these bearings suitable for both road and dirt tracks?

Yes, they work on both surfaces but require more frequent servicing in dirt or wet conditions to prevent contamination.
