Frequently Asked Questions (FAQ)
-
Q: What does 42CrMo4 mean?
A: It is a chromium-molybdenum alloy steel grade (DIN 1.7225) with high hardenability and strength, commonly used for gears and highly stressed bearings. -
Q: Can I use this bearing for a rotating platform that carries 10 tons?
A: Yes, the static load capacity is rated at 10 tons. However, for dynamic applications with continuous rotation, we recommend verifying the dynamic load and speed conditions. -
Q: How does the nylon cage compare to a steel cage?
A: Nylon cage reduces weight, noise, and friction. It also provides self-lubrication and is suitable for moderate speeds. Steel cages offer higher temperature resistance and mechanical strength. -
Q: Is the bearing supplied with gear teeth?
A: This standard model does not include gear teeth, but we can add internal or external gear teeth as a customization (available upon request). -
Q: What is the typical lead time?
A: For standard sizes, lead time is about 15–20 working days. For customized versions, it may extend to 25–30 working days, depending on quantity and complexity. -
Q: Can I get a sample before mass production?
A: Yes, we accept sample orders. Sample cost and shipping are negotiable. For mass orders, the sample cost can be deducted. -
Q: Does the bearing come with a warranty?
A: We offer a 12-month warranty from the date of shipment against manufacturing defects. Please refer to our warranty policy for details. -
Q: What payment methods do you accept?
A: We accept T/T, L/C, and other common methods. Payment terms are negotiable based on order value and history.
