Bulk order satisfied
Purchased 50 units for our production line. Consistency across all units was excellent. No defects found during inspection. Will order again.

Good quality, slight delay
The bearing itself is top-notch quality and matches the specs perfectly. Only giving 4 stars because shipping took a bit longer than expected, but the product is solid.

Durable under high load
Been running these for 6 months continuously. No signs of wear or scoring on the shaft. The flange holds up well against axial loads too.

Great self-lubricating performance
We operate in a dusty environment where grease attracts debris. These graphite bushings solve that issue completely. Smooth operation even under high load.

Perfect fit for hydraulic press
Ordered these for a retrofit on our industrial press. The dimensions were exact, and the self-lubricating feature is saving us significant maintenance time. Highly recommend for heavy machinery.
Q: Do you provide material certification documents?
A: Yes, we can provide mill certificates and material compliance documents upon request after purchase.
Q: What is the maximum rotational speed recommended?
A: For optimal performance and longevity, we recommend a maximum surface speed of 0.5 m/s for continuous operation.
Q: What is the tolerance on the inner diameter?
A: The inner diameter follows standard H7 tolerance specifications suitable for sliding fits.
Q: Can this be used in submerged water applications?
A: While bronze is corrosion-resistant, this specific graphite composite is best suited for dry or occasional moisture exposure, not continuous submersion.
Q: Is special tooling required for installation?
A: Standard press-fit tools are recommended. Ensure the housing bore is clean and deburred before installation.
