What Makes Our Roller Slewing Rings Different?
Our roller slewing bearings stand out through advanced engineering and premium materials. We construct each ring using high-strength 50Mn or 42CrMo alloy steel forgings that undergo specialized heat treatment processes. This ensures maximum durability even under continuous heavy loads.
The precision rollers inside each bearing use GCr15 bearing steel, providing exceptional wear resistance and smooth operation. Our manufacturing process maintains tight tolerances across P0, P6, P5, and P4 precision grades, giving you options for various application requirements.
You'll find our bearings equipped with NBR nitrile rubber seals that resist oil, wear, and aging. These seals protect internal components from contamination while maintaining proper lubrication throughout the bearing's service life.
Configuration Options for Every Application
Single-Row Roller Design
Perfect for applications requiring high radial load capacity with moderate axial loads. This configuration offers compact dimensions while maintaining excellent rotational accuracy.
Double-Row Roller Configuration
Provides enhanced load capacity and improved moment resistance. Ideal for equipment experiencing variable load directions and complex force combinations.
Triple-Row Roller System
Our heaviest-duty option handles extreme loads in all directions. This configuration suits applications like thousand-ton cranes and large excavators where maximum load capacity is essential.
Each Roller Slewing Ring configuration includes pre-drilled mounting holes, lubrication fittings, and protective seals for straightforward installation and maintenance.
