Frequently Asked Questions
Q1: What is the expected service life of this bushing under normal conditions?
A: Service life depends on load, speed, temperature, and contamination. Typically, with proper installation and within rated parameters, the bushing can last several thousand hours under moderate loads. We recommend testing in your specific application.
Q2: Does this bushing require any external lubrication?
A: No, it is self-lubricating. The oil-impregnated bronze matrix provides continuous lubrication for the life of the bushing. However, in severe environments, occasional supplemental grease may extend life.
Q3: Can you customize the bushing dimensions?
A: Yes, we offer custom sizes for OD, ID, length, and chamfer. Please provide a drawing or detailed specifications for a quotation.
Q4: What is the maximum static load this bushing can handle?
A: Static load capacity depends on material and wall thickness. Typically, this bushing can handle up to 50 MPa static pressure. For dynamic loads, please consult our technical team.
Q5: Is this bushing suitable for underwater or high-humidity applications?
A: Yes, the bronze alloy offers good corrosion resistance. However, prolonged submersion may affect the oil retention. We can recommend special coatings if needed.
Q6: How do you ensure product quality?
A: We follow a rigorous quality management system. Each batch undergoes dimensional inspection, porosity test, and friction coefficient verification. We also provide material certificates upon request.
Q7: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15-20 days after order confirmation. Custom sizes may require 25-30 days depending on complexity.
Q8: Do you provide samples for testing?
A: Yes, we offer samples for evaluation. Please contact us to discuss sample availability and shipping costs.
