Great for Appliance Repair
Used these to fix a quiet fan motor in a heater. They run smoothly and silently. Will buy again for future repairs.

Not for High Load
They work well for light duty, but wore out quickly when I tried using them in a higher load application. Stick to low speed uses.

Perfect for RC Motor Repair
These bearings fit my 5mm shaft perfectly. The self-lubricating feature saves me time on maintenance. Highly recommend for hobbyists.

Good Quality, Slightly Tight
Overall good quality bronze bushings. The 3mm ID was slightly tight on my shaft but loosened up after a few minutes of operation.
Q: Can these be used in high-speed applications?
A: These are best suited for low to moderate speed applications. High speeds may generate excessive heat.
Q: Is additional lubrication required during installation?
A: No, these bearings are oil-impregnated during manufacturing and are self-lubricating. Additional oil is not necessary.
Q: What is the primary material composition?
A: They are made using powder metallurgy techniques, primarily consisting of sintered bronze with embedded oil.
Q: Do you offer custom lengths for these bushings?
A: We currently stock standard lengths only. Custom machining services are not available at this time.
Q: Are the sizes listed in metric or imperial measurements?
A: All inner diameter sizes listed (3/4/5/6/8/10 mm) are metric measurements.
