Key Advantages for Your Application
- Customizable Sizing: We offer bespoke dimensions to match your exact mounting requirements, reducing the need for adaptors.
- Non-Gear Design: No internal teeth, making it lighter and more compact – perfect for applications where rotation is driven externally.
- Single Row Ball Configuration: Provides smooth, low-friction rotation with high load capacity for moderate axial/radial loads.
- Durable Materials: Standard 50Mn or 42CrMo steel with induction hardening ensures long service life even under heavy use.
- Proven Sealing: Double lip seals prevent contamination, ideal for harsh environments like construction sites.
- Easy Installation: Pre-drilled mounting holes (optional) and lubrication fittings simplify integration.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a non-gear slewing ring and a geared one?
A: A non-gear slewing ring has no internal or external teeth. It relies on an external driving mechanism (e.g., a separate gear or chain) to rotate. This design is simpler, lighter, and often more cost-effective for applications where the drive system is external.
Q2: Can I request a custom size outside the standard range?
A: Yes, we specialize in custom sizes. Please provide your required inner diameter, outer diameter, and height. Our engineering team will evaluate feasibility and provide a solution. Custom sizes are available upon request.
Q3: What materials are available for this bearing?
A: Standard materials are 50Mn and 42CrMo steel. For special applications, we can use stainless steel or other alloys. Contact us to discuss your specific environment (e.g., corrosion resistance requirements).
Q4: How is the raceway hardened?
A: The raceway surface is induction hardened to HRC 55-62, ensuring wear resistance while maintaining core toughness. This process is applied after machining to achieve consistent depth and hardness.
Q5: What is the typical lead time for custom orders?
A: Lead time depends on size and quantity. Generally, 30-45 days for custom sizes. Standard sizes may be shorter. We can provide an exact schedule after order confirmation.
Q6: Do you provide mounting holes or other custom machining?
A: Yes, we can drill mounting holes, keyways, or other features as per your drawings. These are customizable options. Please specify your requirements.
Q7: Is the bearing pre-lubricated?
A: Yes, each bearing comes pre-filled with lithium-based grease. Lubrication nipples are installed for easy re-lubrication during maintenance.
Q8: What is your shipping policy?
A: We ship from Port of Shanghai, Lianyungang, Qingdao, or Tianjin. We work with reliable freight forwarders to ensure safe and timely delivery. FOB, CIF, or other terms are negotiable.
