Three-Row Roller Slewing Bearing

Three-Row Roller Slewing Bearing: Superior Load Capacity for Heavy-Duty Applications

When you need maximum load capacity in a compact design, the Three-Row Roller Slewing Bearing delivers unmatched performance. This imaginative bearing arrangement highlights three freely organized lines of rollers that productively convey hub loads, spiral powers, and toppling minutes. Not at all like conventional plans, our item changes point contact into line contact, altogether lessening contact stretch whereas maximizing load-bearing capability. Whether you're working with harbour apparatus, mining gear, or wind control establishments, this bearing gives the unwavering quality and strength your operations request.

Exceptional Engineering for Maximum Performance

Our products represent cutting-edge bearing technology. The unique design separates load distribution among three distinct roller rows. Two horizontally positioned roller groups handle axial loads and overturning moments, while one vertically placed group manages radial forces.

This shrewdly stack division makes predominant execution compared to cross-roller or double-row ball choices. You get decreased push on person rolling components and upgraded in general bearing life. The line contact plan gives way better stack dispersion over the bearing surface.

Each bearing comprises of precision-manufactured internal rings, external rings, three roller columns, cages, and progressed fixing frameworks. This arrangement makes our item perfect for applications requiring tall stack capacity with negligible grinding torque.

Premium Materials and Precision Manufacturing

Quality starts with material selection. We use 42CrMo and 50Mn special alloy steel for base components, ensuring exceptional strength and durability. Rolling elements utilize GCr15SiMn high-purity bearing steel for optimal performance.

Our cages incorporate brass, steel, or engineering plastic materials based on your specific requirements. Premium imported nitrile rubber or fluororubber seals protect internal components from contamination.

Manufacturing precision covers four accuracy grades: P0, P6, P5, and P4. Our ISO9001-certified facility maintains strict quality control throughout production. Advanced CNC equipment and rigorous testing ensure every bearing meets international standards.

Versatile Configurations for Every Application

We offer three main configurations to match your equipment needs:

Standard Configuration: Clean, streamlined design without external gearing
