Good quality but tight fit

Quality is top notch. Had to ream slightly for our specific shaft tolerance, but once installed, they perform very well under load.

No grease needed

Saved us significant maintenance time. The graphite plugs work exactly as advertised. Highly recommend for hard-to-reach bearing points.

Perfect fit for our conveyor system

Used these on our main conveyor system. The fit was precise and installation was straightforward. No grease needed so far after 3 months of operation.

High heat resistant

Works well in high heat environments near our furnace equipment. Bronze holds up better than standard polymer bushings in this application.

Bulk order satisfied

Ordered 50 units for our assembly line. Consistency across all parts was impressive. Will order again for future projects.

5 FAQ

Q: What is the recommended shaft tolerance for installation?

A: We recommend a clearance fit of H7/g6 for optimal performance and longevity of the bushing.

Q: Do these require additional oiling during operation?

A: No, the embedded graphite provides sufficient lubrication for most standard applications. Additional oiling is generally not required.

Q: Can these be used in submerged underwater applications?

A: Yes, bronze graphite bushings are suitable for submerged applications and offer good corrosion resistance in water.

Q: Are custom sizes available if these models do not fit?

A: Yes, we offer custom machining services. Please contact our sales team with your specific dimensions for a quote.

Q: What is the maximum rotational speed these can handle?

A: Max speed depends on load and temperature. For continuous operation under max load, we recommend staying under 0.5 m/s sliding velocity.
