Consistent quality across bulk order
Ordered 50 units for our clients. Every single bushing met the specified tolerances. Manufacturer direct pricing made this very cost-effective for our inventory.

Perfect fit for our ceramic kiln motors
We ordered these bushings for a retrofit on our large ceramic machinery. The dimensions were precise and the oil-impregnated material works smoothly. Highly recommend for industrial use.

Good quality, slight shipping delay
The copper bushings are solid and well-made. They fit the motor shafts perfectly. Only giving 4 stars because shipping took a bit longer than expected, but the product itself is excellent.

Durable and reliable
Been using these in our production line for three months now. No signs of wear yet. The self-lubricating feature saves us maintenance time. Great value for bulk orders.
Q: Do these require additional lubrication during installation?
A: These are oil-impregnated bushings designed to be self-lubricating. However, applying a thin layer of machine oil during initial installation is recommended for optimal break-in.
Q: What is the maximum rotational speed these can handle?
A: For standard sizes, the recommended maximum surface speed is approximately 300 feet per minute. Higher speeds may require specific clearance adjustments.
Q: What is the typical lead time for large orders?
A: Standard sizes are usually shipped within 3-5 business days. Large bulk orders or custom specifications typically require 10-15 business days for production and quality check.
Q: Are these resistant to corrosion in humid environments?
A: Copper alloy offers good natural corrosion resistance. For highly humid or corrosive environments, we recommend applying a protective coating or selecting our stainless steel alternatives.
Q: Can these bushings be customized to non-standard sizes?
A: Yes, we offer custom machining services. Please contact our support team with your specific dimensions and quantity requirements for a quote.
