Three-Row Cylindrical Roller Slewing Bearing

Three-Row Cylindrical Roller Slewing Bearing

Product Details

When your heavy equipment demands exceptional load capacity and reliability, the Three-Row Cylindrical Roller Slewing Bearing delivers exactly what you need. This bearing features an innovative design with three independent rows of cylindrical rollers that work together to handle axial forces, radial loads, and overturning moments simultaneously. Two horizontal rows manage axial loads and tilting moments, while one vertical row controls radial forces and maintains rotational centering. This smart load distribution changes point contact to line contact, significantly reducing contact stress. The result? You get higher load capacity in the same envelope size compared to traditional ball or cross-roller designs.

At Luoyang Heng Guan Bearing Technology Co., Ltd., we manufacture these bearings with diameters ranging from 500 mm to 10,000 mm. We utilize premium materials such as 42CrMo alloy steel for the rings and GCr15SiMn high-carbon chromium bearing steel for the rollers.

Features and Benefits

Superior Load Distribution

The three-row configuration intelligently separates loads. You benefit from reduced stress on each roller, which translates to a longer service life and reduced maintenance intervals.

Line Contact Technology

Unlike point contact designs, line contact increases the effective load-bearing area. This means you can handle heavier loads without increasing the bearing size.

High Rigidity Structure

The robust design maintains dimensional stability under load. Your equipment maintains precision even during heavy-duty operations.

Integrated Sealing

Both sides are sealed and pre-lubricated with high-quality grease. Relubrication points make scheduled maintenance straightforward.

Flexible Mounting

Bolt-on mounting simplifies both initial assembly and future replacement. You save time and reduce downtime.

Custom Gear Integration

Choose internal, external, or no gear configuration based on your drive system requirements.

Applications

This Three-Row Cylindrical Roller Slewing Bearing type excels in heavy industrial environments:

· Port Machinery: Ship-to-shore cranes, container handlers, and bulk material equipment

· Mining Equipment: Bucket-wheel excavators, stackers, reclaimers, and rotary drills

· Metallurgical Equipment: Converters, ladle turrets, and continuous casting machines

· Wind Power: Direct-drive turbine main Shafts and yaw systems

· Special Engineering: Shield tunneling machines and heavy-lift platforms

· Manufacturing: Turntables, welding positioners, and assembly fixtures

Installation Guide

Preparation

Inspect mounting surfaces for flatness and cleanliness. Remove protective coatings from the bearing. Check bolt holes for alignment.

Mounting Steps

1. Position the bearing on the lower mounting surface

2. Align bolt holes carefully

3. Insert bolts but do not fully tighten

4. Check concentricity and adjust if needed

5. Tighten bolts in a cross pattern to specification

6. Install the upper structure

7. Verify smooth rotation before final assembly

Important Notes

Avoid impact during installation. Ensure proper bolt grade and torque. Verify seal integrity after mounting.

Exhibition

We attend many famous international exhibitions such as Shanghai International Maritime Exhibition,Mining World Russia, bauma China, CTT Russia, etc

Maintenance and Care

Lubrication Schedule

Relubricate every 100 to 500 operating hours, depending on the load and operating environment. Use a lithium-based grease with Extreme Pressure (EP) additives.

Regular Inspection

Monthly: Check for abnormal noise or vibration.

Monthly: Inspect seals for damage or leakage.

Quarterly: Check and re-tighten bolts to the specified torque.

Operation Monitoring

Continuously monitor the bearing's operating temperature.

Note any increase in rotation resistance.

Record significant load conditions and work cycles for maintenance reference.

Storage Guidelines

Store the bearing horizontally on a flat, level surface in a clean, dry environment.

Do not remove the factory-applied anti-corrosion coating until the bearing is ready for installation.

For long-term storage, rotate the bearing 90 degrees every three months to prevent permanent deformation from static load.

FAQ

Q: What loads can this bearing handle?

A: It oversees hub, outspread, and toppling minutes at the same time. Contact Us with your particular stack values for sizing.

Q: How does it compare to ball slewing bearings?

A: It offers higher stack capacity in the same estimate due to line contact versus point contact.

Q: Can you customize the bearing dimensions?

A: Yes, we make custom sizes past standard ranges and can reverse-engineer from your existing components.

Q: What's the ordinary lead time?

A: Standard sizes dispatch inside 2-3 weeks. Custom orders require 4-8 weeks depending on complexity.

Q: Do you give establishment support?

A: We offer establishment direction, specialized documentation, and can orchestrate on-site back for basic applications.

Q: What exactness review ought to I choose?

A: P0 suits common applications, P6 for standard exactness, P5 for tall precision, and P4 for basic accuracy necessities.
