Good quality, tight tolerance
The material feels very solid and durable. The inner diameter was slightly tight for our existing shafts, required some polishing, but otherwise a great product for the price.

Great self-lubricating performance
We needed something that didn't require constant greasing in a dusty environment. These copper sleeves with graphite plugs are working perfectly. Very satisfied with the quality.

Durable under high load
Using these in a hydraulic application with significant side load. They have held up much better than the previous plastic bushings we used. Highly recommend for industrial use.

Fast shipping and well packaged
Arrived earlier than expected. Each bushing was individually wrapped to prevent damage. The SHRZ quality mentioned in the description is evident in the finish.

Perfect fit for our machinery
Ordered the 20mm ID version for a repair on our packaging line. The dimensions were spot on and the press fit was smooth. No squeaking after two weeks of continuous operation.
Q: What is the recommended press fit tolerance for the outer diameter?
A: We recommend a tolerance of H7 for the housing bore to ensure a secure press fit without damaging the copper alloy.
Q: What is the maximum misalignment this bushing can tolerate?
A: To prevent edge loading and premature wear, we recommend keeping shaft alignment within 0.5 degrees.
Q: Are custom lengths available for this model?
A: Standard lengths are in stock. For custom lengths, please contact us directly. Production time for custom sizes is typically 5-7 business days.
Q: Can these bushings be used with stainless steel shafts?
A: Yes, this copper alloy material is compatible with hardened steel and stainless steel shafts without causing excessive wear.
Q: Do I need to apply any grease during installation?
A: No additional lubrication is needed for operation. However, a light coat of oil on the outer diameter can assist with the press fit installation process.
