FAQ

What types of loads can the 5304‑2RS bearing handle?

The bearing is designed to support both radial loads and axial loads in one direction, thanks to its angular contact geometry. This makes it ideal for high‑speed shafts that experience combined stresses.

How does the double rubber seal improve performance?

The dual seals create a barrier that prevents ingress of dust, water, and chemicals while retaining lubrication inside the bearing. This reduces wear, minimizes the need for frequent re‑lubrication, and helps maintain consistent performance over time.

Can the bearing be used in high‑temperature environments?

Yes, the steel alloy and seal materials are rated for typical industrial temperature ranges up to 120 °C (248 °F). For extreme temperatures, additional cooling or specialized seal options may be required.

Is the 10‑piece pack suitable for large‑scale projects?

Absolutely. The pack of ten provides a cost‑effective solution for bulk installations, maintenance programs, or inventory stocking, ensuring you have enough units for multiple machines or replacement cycles.

What warranty does QJZ offer on this bearing?

QJZ provides a standard one‑year limited warranty covering manufacturing defects. Our technical support team is available to assist with installation guidance, troubleshooting, and any warranty claims.
