Frequently Asked Questions
-
Q: What materials are available for your powder metal oil-impregnated bushings?
A: We offer sintered bronze (CuSn10) and iron-based alloys (Fe-Cu, Fe-Cu-C). Custom materials are possible upon request with sufficient order quantity.
-
Q: How long does the oil last in the bushing?
A: The oil is impregnated into the porous structure and is gradually released during operation. Under normal conditions, the bushing can last for thousands of hours without re-oiling. The actual life depends on load, speed, and temperature.
-
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide samples for evaluation. You can request a sample with your specific dimensions, and we will quote accordingly. Sample lead time is usually 7-15 days.
-
Q: What is the tolerance range for your bushings?
A: Standard tolerances are IT7-IT8 for inner diameter and IT8-IT9 for outer diameter. Tighter tolerances can be achieved with additional machining.
-
Q: Do you provide a Mill Test Report with every shipment?
A: Yes, a Mill Test Report including chemical composition, density, hardness, and oil content is included with each order. Additional testing reports can be provided at extra cost.
-
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the size and complexity. For standard sizes, MOQ is typically 500 pieces. For custom sizes, minimum order quantity is negotiable.
-
Q: How do I select the right bushing for my application?
A: Please provide operating conditions such as load (static/dynamic), speed, temperature, and environment. Our technical team can recommend the optimal material, oil content, and dimensions.
-
Q: What is the warranty coverage?
A: All our powder metal oil-impregnated bushings are covered by a 1-year warranty against manufacturing defects. This includes excessive wear due to material or process issues. Normal wear in service is not covered.
