Frequently Asked Questions (FAQ)
Q1: What is a self-lubricating bronze bushing?
A: It is a bushing made from sintered bronze that is impregnated with oil. During operation, the oil slowly releases to provide lubrication, reducing friction and wear without external oil supply.
Q2: How long does the lubrication last?
A: The lubrication life depends on operating conditions (load, speed, temperature). Under normal conditions, it can last for the entire service life of the bushing, often exceeding thousands of hours.
Q3: Can I get custom sizes?
A: Yes, we offer customizable inner diameter, outer diameter, and length. Please provide your required dimensions, and we will produce accordingly.
Q4: Is the Mill Test Report included for every order?
A: Yes, a Mill Test Report covering chemical composition and mechanical properties is included with each shipment for quality assurance.
Q5: What is the warranty coverage?
A: The 1-year warranty covers manufacturing defects such as cracks, porosity, or dimensional deviations. Normal wear and tear are not covered.
Q6: Can these bushings be used in water or corrosive environments?
A: Bronze has good corrosion resistance, but for continuous water submersion or highly corrosive chemicals, we recommend our special alloy options. Please consult our technical team.
Q7: What is the minimum order quantity (MOQ)?
A: MOQ is typically 100 pieces for standard sizes. For custom sizes, MOQ may vary. Contact us for details.
Q8: How are the bushings packaged for export?
A: They are packaged in plastic bags, then in cartons or wooden crates, with proper cushioning to prevent damage during transit.
