Technical Specifications

Load Capacity You Can Trust

Worried about raceway fracture or equipment tipping under heavy loads? Your concerns are valid. The heavy duty slewing ring bearing for crane is engineered with reinforced raceway design and finite element analysis optimization. Our three-row roller configuration provides superior line-contact dynamics compared to ball bearings, dramatically increasing stiffness and load distribution.

The 42CrMo material offers exceptional tensile strength to prevent deformation and cracking during peak operation. Advanced induction hardening reaches depths of 3-5mm at HRC 55-62, ensuring outstanding resistance to brinelling and rolling contact fatigue. This translates to extended service life and reduced replacement frequency—even in the most demanding tower crane applications.

Our engineering team conducts rigorous load calculations and provides technical documentation, so you select the right bearing every time.

Gear Options to Match Your Design

The three row roller slewing bearing with external gear comes in flexible configurations:

· External Gear: Ideal for direct pinion engagement in standard tower crane designs

· Internal Gear: Perfect for compact installations requiring space efficiency

· Without Gear: For custom drive systems or retrofit applications

Each gear option undergoes precision hobbing on our large CNC gear hobbing machines and selective hardening to balance wear resistance with impact toughness. Whether you need 1:1 OEM replacement or custom tooth profiles, we've got you covered.

Applications Across Heavy Industries

This 1405×1795×220mm slewing bearing excels in:

· Tower Cranes: Primary application for construction sites demanding reliable rotation under load

· Port Cranes: Handles saltwater corrosion with optional anti-corrosion coatings

· Large Excavators: Supports boom rotation with high moment capacity

· Stacker-Reclaimers: Withstands continuous duty cycles in bulk material handling

Our team understands your industry's working conditions. We provide application-specific engineering support to ensure optimal 130.40.1600 slewing bearing selection for your equipment's operational profile.

FAQ

Q: Can this slewing bearing hold a lot of weight without breaking?

A: Yes, of course. Our improved heat treatment, strengthened raceway design, and high-strength 42CrMo material all work together to make sure that they perform exceptionally well under heavy loads. Before production starts, we use finite element analysis to make sure the structure is solid.

Q: When will the 130.40.1600 bearing be replaced?

Q: The service life relies on how the bearing is used, but our optimized heat treatment, use of wear-resistant materials, and careful manufacturing usually make them last 20–30% longer than standard bearings. It is very important to lubricate and maintain things correctly.

Q: Does this bearing fit the tower crane I already have?

A: We're experts at OEM replacement parts that fit exactly the same size. Send us information about your equipment or old bearing markings, and our engineers will check to see if they are compatible, even if they don't have the original drawings.

Q: What should I do if I need specific sizes or features?

A: We're best at making custom products. We can handle designs that aren't standard, coatings that are made for corrosive environments, and gear setups that have been changed. If you don't have drawings, our on-site measurement and reverse engineering services can make exact specs for you.

Q: How quickly can you deliver?

A: Most combinations ship between 15 and 20 days. On average, it takes 30 to 45 days to make a custom order, but this depends on how complicated it is. We keep popular models in stock so that we can quickly replace broken ones.

Q: Do you offer help with installations?

A: Assuredly. We provide detailed instructions for installation and technical writing. For very important jobs, our engineers can help with installation on-site to make sure everything is lined up correctly and works at its best.
