Enhance Rotation Precision with XRAY Bearings

The 13x19x4mm XRAY 941319 bearings come in a two-piece set to improve drivetrain precision and lower rolling resistance. Their build quality aims to keep running smooth across a range of driving conditions.

Performance-Focused Construction

A larger ball count within the cage helps distribute loads for steadier operation during aggressive driving. Rubber seals prevent grime ingress and still allow the side covers to be removed for servicing.

Reduced Friction and Practical Serviceability

Light grease is fitted at the factory to give immediate smooth running, and the bearings respond well to periodic cleaning and re-lubrication for extended service life. They balance low drag with durability for track 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.

Are these compatible with kits that list 13x19x4 bearings?

Yes, they match the 13x19x4 dimension used in many kits, but check any spacers or snap rings that might affect fit.

How frequently should I check these bearings?

Inspect after wet or particularly dusty runs and perform a full clean and relube if you notice noise or increased resistance. Routine checks after race days are sensible.

What lubricants work best for these sealed bearings?

Use a light, fast-penetrating bearing oil or a thin synthetic grease intended for RC bearings to keep friction low while protecting surfaces.
