Good value for industrial use
The bushings are high quality bronze. Slightly tight fit initially but wore in nicely after a few cycles. Would order again for maintenance stock.

Perfect fit for heavy machinery
Used these on an excavator arm joint. The self-lubricating feature saves us time on greasing schedules. Fit was precise and installation was straightforward.

Bulk order satisfied
Ordered 50 units for a client project. All measurements matched the spec sheet perfectly. Great wear resistance observed so far in high-load applications.

Long lasting performance
Replaced standard brass bushings with these graphite bronze ones. They are handling the load much better without overheating. Lifespan seems doubled.

Solid product, slow shipping
Works well in dusty environments where oil attracts dirt. Shipping took a bit longer than expected but the product quality makes up for it.

A: We recommend an H7/h6 interference fit for optimal housing stability and performance.
Q: Do these offer corrosion resistance for outdoor use?
A: Yes, the copper alloy provides good corrosion resistance suitable for most outdoor industrial environments.
Q: What is the maximum sliding speed these can handle?
A: Depending on the load, they typically handle sliding speeds up to 0.5 m/s continuously.
Q: What is the return policy if the dimensions are incorrect?
A: We accept returns within 30 days if the item is unused and in original packaging. Please contact us for a RMA.
Q: Are these bearings completely oil-free during operation?
