As a professional manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. specializes in high-quality excavator slewing bearings. Established in 2022, our factory spans 10,000–30,000 square meters, equipped with advanced CNC machines and heat treatment facilities. Our Hydraulic Excavator Slewing Bearing for 45 ton class is engineered for long service life and direct replacement fitment, ensuring minimal downtime and maximum productivity for your heavy equipment.
This slewing bearing is designed to meet the rigorous demands of 45-ton hydraulic excavators, offering smooth rotation, high load capacity, and excellent durability. It is a direct replacement for OEM parts, simplifying maintenance and reducing inventory costs.
Key Features & Technical Specifications
- Material: Premium 50Mn forged steel, heat-treated for surface hardness of HRC 55–60, with hardened raceways to resist wear and deformation under heavy loads.
- Bearing Type: Single row four-point contact ball bearing, optimized for combined axial, radial, and moment loads typical in excavator slewing motions.
- Sealing System: Double-lip nitrile rubber seals with dust lip, providing superior protection against dirt, water, and debris—critical for harsh job sites.
- Gear Options: Available with internal or external gear (module 10–16, teeth hardened), customizable to match your excavator model’s existing slew drive.
- Long Service Life: Raceways undergo precision grinding and induction hardening, achieving a rated life of over 10,000 hours under normal operating conditions.
- Direct Replacement: Designed to match OEM dimensions (outer diameter, inner diameter, height, bolt hole patterns, gear parameters) for bolt-on installation, no modification required.

Frequently Asked Questions (FAQ)
-
Q: Is this slewing bearing a direct replacement for OEM parts?
A: Yes, it is designed as a direct replacement. We match the original dimensions, bolt patterns, and gear specifications for 45-ton class excavators. Please provide your machine model or OEM part number for confirmation. -
Q: What is the typical lifespan of this bearing?
A: Under normal operating conditions with proper lubrication and maintenance, the bearing can exceed 10,000 hours of service life. The hardened raceways and premium seals contribute to its long durability. -
Q: Can you customize the gear type (internal vs. external) or module?
A: Absolutely. Both internal and external gear options are available, and gear module can be customized from 10 to 16 to match your existing slew drive. Please specify your requirements. -
Q: What material is used for the bearing rings?
A: We use 50Mn forged steel with induction hardened raceways (HRC 55–60). This material provides excellent wear resistance and impact toughness for heavy-duty excavator applications. -
Q: How is the bearing packaged for export?
A: Each bearing is individually wrapped with anticorrosion paper, placed in a wooden crate with foam padding, and secured for sea freight. We ensure protection against rust and mechanical damage during transit. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ is typically 1 piece for sample orders, and 10–20 pieces for bulk orders. We also accept small trial orders to test fitment and quality. -
Q: Do you offer a warranty?
A: Yes, we provide a 12-month warranty from the date of shipment against manufacturing defects. This covers raceway flaking, material cracks, and premature wear under normal use. -
Q: How can I confirm the dimensions for my excavator model?
A: Please send us your excavator model (e.g., Komatsu PC450, Caterpillar 345, Hitachi ZX450) or provide the original bearing’s outer diameter, inner diameter, height, and bolt hole pattern. We will cross-check with our database and offer a matching solution.
