Frequently Asked Questions (FAQ)
-
What is the typical load capacity of a 300mm OD thin section slewing bearing?
Dynamic axial load capacity typically ranges around 15 kN, and radial capacity around 10 kN, but exact values depend on the specific cross-section and material choice. Contact our engineers for a detailed calculation based on your load conditions. -
Can the mounting hole pattern be customized for my existing flange?
Yes, we can produce bearings with custom bolt circle diameters, hole sizes, and number of holes to match your interface. Provide a drawing or specifications for a no-obligation quotation. -
Are these bearings suitable for outdoor or washdown environments?
Standard bearings are made of steel; for outdoor or washdown applications, we recommend adding a protective coating (e.g., zinc or nickel plating) or ordering a stainless steel variant. Seals are also available upon request. -
What is the maximum operating speed for this bearing?
Thin section bearings are not typically designed for high speeds; maximum rotational speed depends on lubrication and load. For guidance, please provide your application RPM, and we will recommend a suitable design. -
Does the bearing come pre-lubricated?
Standard bearings are supplied with a lithium-based grease; alternative greases or oil lubrication can be specified. We also offer options for relubrication holes or grease nipples. -
How do you ensure the bearing's precision and quality?
Every bearing undergoes 100% inspection of dimensions, raceway hardness, and rotation torque. Our quality management system follows ISO 9001 principles (certification available upon request). -
What is the lead time for a standard 300mm OD thin section slewing bearing?
Lead time for standard models is typically 15–25 working days. For custom designs, please allow 25–40 days depending on complexity. -
Can I get a sample bearing for testing before placing a bulk order?
Yes, we accept sample orders. Minimum order quantity for samples may apply; contact our sales team for details.
