Frequently Asked Questions (FAQ)
-
Q: What is the typical delivery time for this slewing bearing?
A: For standard models, delivery is approximately 30–45 days after order confirmation. Customized designs may require additional time. Please contact our sales team for exact lead times. -
Q: Can the bearing be customized for different gear modules or tooth numbers?
A: Yes, we offer customization of gear parameters including module, number of teeth, and pressure angle. Please provide your requirements for a tailored solution. -
Q: How does the UV resistance work in practice?
A: The bearing seals and external coatings are formulated with UV stabilizers and additives that prevent cracking, fading, or embrittlement when exposed to sunlight for extended periods. This ensures reliable sealing over the 30-year service life. -
Q: What maintenance is required for this bearing?
A: The bearing is pre-lubricated with high-quality grease and sealed. We recommend periodic inspection every 6 months and re-greasing every 2–3 years depending on operating conditions. Detailed maintenance instructions are provided with the product. -
Q: Is the bearing suitable for use in coastal areas with high humidity and salt spray?
A: Yes, we can provide additional corrosion protection such as zinc-nickel plating or stainless steel raceways upon request. Standard models are designed for typical outdoor environments; for extreme conditions, please consult our engineers. -
Q: What is the maximum axial load capacity?
A: The static axial load capacity can reach up to 150 kN for the 1m OD design, depending on the raceway geometry and material. Dynamic load capacity is lower; please refer to our technical datasheet for specific values. -
Q: Do you provide samples for testing?
A: Yes, we can provide sample bearings for evaluation. Sample cost and shipping terms are negotiable. Please contact us to discuss your testing needs. -
Q: How do I ensure the bearing is properly mounted?
A: We provide a mounting instruction manual with each bearing. It is important to use proper torque for bolts and ensure alignment. Our technical support team is available to assist with installation questions.
