Durable and reliable
Replaced worn-out sleeves in a conveyor system. These have been running for months without noise. Highly recommend for industrial use.

Excellent for hobby projects
Using these for a custom 3D printer build. They run smooth and quiet. The oil impregnation seems consistent across the batch.

Perfect fit for motor repair
Ordered the 10mm bushings for an old electric motor. The fit was precise and the self-lubricating feature works great. No need for extra grease.

Good quality, slight variance
Overall very satisfied with the bronze quality. One bushing was slightly tighter than the others for press fit, but manageable with an arbor press.

Great value for money
Bought a mix of sizes for my workshop. Prices are competitive compared to local suppliers. Shipping was fast too.
Q: What is the recommended press fit tolerance for the outer diameter?
A: We recommend a standard interference fit of approximately 0.02mm to 0.05mm depending on the housing material.
Q: Are these resistant to corrosion in humid environments?
A: Bronze offers good natural corrosion resistance. They are suitable for most humid environments but not recommended for submerged saltwater use.
Q: Do these bushings require additional lubrication during installation?
A: No, these are oil-impregnated and self-lubricating. However, adding a light coat of oil during installation can help prevent galling.
Q: Is it safe to cut these bushings to a custom length?
A: Yes, but please note that cutting may seal the pores at the cut edge. Re-oiling the cut surface is recommended.
Q: Can these be used in high-speed applications over 3000 RPM?
A: For speeds exceeding 3000 RPM, we suggest ensuring adequate heat dissipation or consulting our engineering team for specific load calculations.
