Precision Ball Bearings XRAY 941321

The XRAY 941321 13x20x4mm steel sealed ball bearings are engineered for consistent rolling performance and long-term reliability. They are a sensible component for those setting up an XB8E 2016 chassis.

Fine-Tuned Grease and Seal Protection

Each unit includes a small amount of lubricant to balance smooth running with longevity, while the sealed steel shields reduce intrusion of dust and fine particles that can cause wear.

Exact Match for XB8E 2016 Requirements

With precise 13x20x4mm sizing, these bearings are designed to fit XB8E 2016 bearing seats accurately, helping to preserve alignment and reduce drivetrain play.
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.

What is the best way to clean sealed bearings?

Wipe external seals and use a gentle solvent if contamination is present, then reapply a light lubricant suitable for sealed bearings to avoid seal damage.

Can I use them in high speed applications?

They perform well at typical RC speeds for the XB8E 2016; for sustained extreme RPMs check bearing spec limits and consider alternatives if needed.

Will these reduce drivetrain play?

A precise 13x20x4mm bearing set installed correctly will help minimise play compared with worn or undersized bearings, improving control feedback.

How noisy are sealed bearings?

Sealed and properly greased bearings are typically quieter than open, dry bearings; noise can increase if seals are damaged or contamination builds up.

Where should I source replacements?

Purchase from reputable RC parts suppliers that list XRAY 941321 or generic 13x20x4mm sealed steel bearings to ensure correct fit and quality.
