Good quality bronze

Material feels solid and heavy duty. Took off one star because shipping took longer than expected, but the product itself meets specs.

Exact dimensions as listed

Measured the ID and OD with calipers. Tolerances are within standard range. Very satisfied with the precision.

Excellent self-lubricating performance

Using these in a high-load low-speed application. The graphite plugs work well even in dusty conditions. Highly recommend for industrial use.

Durable bushing

Been running for 3 months now without issues. Seems very wear-resistant. Would buy again for future projects.

Perfect replacement for excavator arm

Ordered the 70mm ID version. Fit was precise and installation was straightforward. No need for constant greasing which saves maintenance time.

5 FAQ

Q: Does this require any initial grease during installation?

A: No, the graphite plugs provide immediate lubrication. However, a thin film of oil on the OD can help during press-fit installation.

Q: What is the maximum sliding speed recommended?

A: For optimal lifespan, we recommend a sliding speed below 0.5 m/s under high load conditions.

Q: Do you offer custom lengths for the 65mm ID option?

A: Yes, we can machine custom lengths. Please contact our sales team with your required dimensions for a quote.

Q: What is the tolerance class for the inner diameter?

A: Standard tolerance is H7 for the inner diameter unless custom specifications are requested.

Q: Can this bearing operate submerged in water?

A: Yes, the bronze material is corrosion resistant and suitable for wet environments, though fresh water is preferred over salt water.
