Roller Slewing Ring

1.Product Introduction: Commonly known as roller-type slewing bearings, with cylindrical or tapered rollers as the load-bearing components. They have stronger load-bearing capacity than those with balls, are impact-resistant, and are suitable for heavy-load equipment.
2.Structure Type: It has a thick-wall annular shape. The inner and outer rings are made of alloy structural steel, with built-in single-row or multi-row rollers, steel cages, heavy-duty seals to prevent impurities, and the mounting holes have anti-loosening designs.
3.Size Range: Outer ring diameter: 500 - 3000mm, inner ring diameter: 450 - 2850mm, height: 25 - 100mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Port cranes, metallurgical equipment, large wind power main units, heavy-duty mining machinery.
6.Key Inspection Items: Roller assembly clearance, anti-overturning moment performance, dust-proof performance of seals.

Product Description

High-Performance Roller Slewing Rings for Heavy-Duty Machinery – Custom Engineered for Harsh Conditions

ISO-Certified Manufacturer with 30+ Years of Expertise in Metallurgy, Port, and Construction Applications

When your heavy machinery demands reliability under extreme stress, roller slewing rings deliver unmatched performance. These robust bearings use cylindrical or tapered rollers—instead of balls—to handle higher loads, resist impacts, and endure harsh environments like steel mills, port cranes, and mining sites. At LUOYANG INNO BEARING CO., LTD, we’ve spent three decades perfecting slewing ring designs that combine precision engineering with industry-specific durability.

Where Our Roller Slewing Rings Excel?

🏗️ Metallurgical Equipment
Survive molten metal environments with our high-temperature slewing rings: special heat treatment prevents warping at 150°C, and 42CrMo4 steel cores resist thermal fatigue.

🚢 Port Machinery
Keep container cranes running with corrosion-resistant designs: fluororubber seals block saltwater ingress, and 100% final inspection verifies a 5,000-hour lifespan.

🌪️ Wind Turbines
Ensure smooth yaw/pitch control in turbines: multi-row roller designs handle uneven loads, and IoT-ready models enable predictive maintenance.
