Refine Your RC Rolling Efficiency

For tighter, more reliable rotation in wheels, differentials and idlers, consider the XRAY 931319 13x19x4 steel sealed ball bearings. They deliver an accurate fit that reduces play and keeps components tracking true session after session.

Steel Construction and Sealed Protection

These XRAY 931319 bearings are made from durable steel for good wear resistance and load handling. The sealed profile helps keep contaminants out, which preserves the internal lubricant and prolongs service intervals on rough layouts.

Compatibility and Installation Tips

The 13mm bore, 19mm outer race and 4mm width match many common RC parts. Press them into housings squarely and check for free spin without binding. They are user friendly for hobbyists upgrading running gear.
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 do I check if the bearing size is correct?

Measure the shaft and housing bores or consult your model's parts diagram. Match 13x19x4mm to the required spec to ensure proper fit.

What lubricant should I use if servicing them?

Use a light bearing oil or low-viscosity bearing grease made for ball bearings. Apply sparingly to avoid trapping dirt under the seals.

Can sealed bearings be used in differentials?

Yes, they are commonly used in diffs and drivetrains where compact sealed bearings are required, as long as the dimensions match the housing.

Should I replace all bearings at once?

Not always necessary, but replacing bearings in pairs or sets avoids uneven wear and helps maintain balanced handling. Inspect others for play before deciding.
