In modern construction machinery, the slewing bearing plays a critical role in connecting the upper structure to the undercarriage and enabling smooth 360° rotation. For 12-ton excavators, selecting the right slewing bearing is essential for safety, precision, and operational efficiency.
Superior Load Capacity and Anti-Tilting Performance
Compared to traditional single row ball slewing bearings, a double row ball slewing bearing offers significantly higher load capacity and superior anti-tilt performance. Engineering tests and field applications have shown that using a double row design can reduce the inclination risk of a 12-ton excavator by approximately 30%, ensuring safer operation on slopes, uneven terrain, and heavy-duty work conditions.
Precision Internal Gear Design
Our internal gear slewing bearing features teeth on the inner ring that precisely mesh with the drive pinion, providing smooth and responsive rotation. The outer ring remains smooth and free of teeth, which reduces friction, simplifies maintenance, and ensures efficient lubrication. Coupled with a heavy-duty slewing ring made from high-strength steel and precision heat treatment, each bearing is rigorously inspected for dimensional accuracy, guaranteeing stable support for the entire machine.
High Performance Under Complex Loads
An excavator slewing bearing must withstand not only vertical loads but also radial forces and overturning moments. The double row ball arrangement distributes the load evenly across two rows of balls, reducing local wear and extending service life. Optimized sealing and lubrication systems ensure that the rolling elements and raceways operate in excellent condition, minimizing maintenance frequency and maximizing uptime.
Wide Industrial Applications
Our industrial slewing bearings are widely used across various construction machinery and industrial equipment, including excavators, cranes, rotary drilling rigs, and port machinery. Whether in single-machine operation or continuous heavy-duty tasks, the turntable bearing provides reliable support, ensuring stable rotation in challenging environments.
