Frequently Asked Questions (FAQ)
Q1: What exactly is included in the Mill Test Report (MTR)?
A1: The MTR is a certified document from the steel mill. It provides detailed information on the material batch used for your bearings, including chemical composition analysis, mechanical property tests (like tensile strength and hardness), heat treatment records, and compliance with specified material standards. This ensures full traceability.
Q2: What does the 18-month warranty cover?
A2: Our warranty covers defects in materials and workmanship under normal use and service conditions for 18 months from the date of shipment. It includes replacement of the defective bearing. Warranty terms and the process for claims will be detailed in our commercial agreement.
Q3: Can you provide custom-designed bearings for my specific application?
A3: Yes, we offer customization services. Our engineering team can work with you on specifications including dimensions, load ratings, sealing types, lubrication, and special tolerances. Please provide your application details and requirements for a feasibility study and quotation.
Q4: What types of rotating bearings do you mainly supply?
A4: We supply a wide range, including but not limited to Deep Groove Ball Bearings, Angular Contact Ball Bearings, Tapered Roller Bearings, Spherical Roller Bearings, Cylindrical Roller Bearings, and large-diameter Slewing Ring Bearings. The optimal type depends on your load, speed, and mounting requirements.
Q5: What are the available shipping options and lead times?
A5: We ship globally via sea freight from major Chinese ports (Shanghai, Qingdao, Tianjin, Lianyungang). Air freight and express options are available for urgent orders. Standard lead times vary based on product type and quantity; typical production lead time for standard items is 30-45 days. We provide a precise schedule upon order confirmation.
Q6: Do you offer samples for testing and evaluation?
A6: Yes, we can provide samples for qualified B2B buyers. Sample availability, cost, and lead time depend on the specific bearing model. Please contact our sales team with your sample request and intended use case.
Q7: How do you ensure consistent bearing quality?
A7: Quality is integrated into our process. We utilize advanced manufacturing equipment, implement Statistical Process Control (SPC), and conduct rigorous inspections at every stage—from raw material incoming checks to final dimensional and performance testing. Our ISO 9001 and IATF 16949 certified quality management system provides the framework.
Q8: What is the minimum order quantity (MOQ)?
A8: The MOQ varies depending on the bearing type and size. For standard bearings, MOQ can be as low as one carton or pallet. For custom-designed bearings, a higher MOQ may apply. We strive to be flexible; please inquire with your specific needs for an accurate MOQ.
