Good Quality Material

The bronze feels solid and well-made. Took off one star because shipping took longer than expected, but the product itself is great.

Perfect Fit for Conveyor Repair

Ordered these for a conveyor belt repair job. The dimensions were spot on and installation was straightforward. The self-lubricating feature saves us maintenance time.

Tight Tolerance

The bearing was slightly tight on the shaft. Had to ream it out a bit to get a smooth fit. Works fine now but required extra effort.

Excellent Durability

We have been running these in a high-load application for three months now with no signs of wear. Highly recommend for industrial use.

5 FAQ

Q: Does it need extra grease during installation?

A: No, these are oil-impregnated and self-lubricating. Additional grease is not required unless specified for extreme conditions.

Q: Is the inner surface finished for smooth rotation?

A: Yes, the inner diameter is finished to ensure smooth rotation against the shaft without additional machining.

Q: Is this suitable for high vibration environments?

A: Yes, the sintered bronze structure provides good damping properties suitable for moderate vibration applications.

Q: Can this bearing be used underwater?

A: Not recommended for submerged applications. While oil-impregnated, prolonged water exposure may wash out the lubricant.

Q: What is the hardness rating of the material?

A: The material hardness is approximately 40 HRB, providing a good balance between wear resistance and conformability.
