Built to deliver steady rotation, the 10x15x4mm bearings from XRAY reduce friction for cleaner drivetrain performance. Their construction focuses on balance and repeatable rolling under load.
The rubber seals keep dirt out of the races while the pre-applied grease preserves smooth operation between services. This setup cuts down on routine attention for everyday running.
These bearings fit a broad range of roles from wheel bearings to gearbox supports, making them a practical maintenance item for hobbyists seeking reliable component performance.
