Single-row ball slewing ring

Single-row ball slewing bearings are a commonly used lightweight bearing type. They are primarily composed of an inner ring, outer ring, steel balls, and a cage. The steel balls and raceways form a four-point contact pattern, capable of withstanding both axial and radial loads. These bearings offer a compact structure, light weight, and high precision.

Single-row ball slewing ring

Single-row ball slewing bearings features

Design Features:

Single-row ball slewing bearings have only one row of rollers, separated by spacers. They offer 360-degree rotation and low friction. Available in split and integral configurations, they can withstand both axial and radial forces.

Manufacturing Process:

Inner and outer rings are typically made of materials such as 42CrMo, 50Mn, and 45# steel, with a quenched and tempered hardness between 170HB and 340HB, ensuring durability and a long service life. Rolling elements are typically made of GCr15 or GCr15SiMn bearing steel, with a hardness of 58-62HRC. Cages are typically made of nylon, and seals are typically made of butyl rubber or fluororubber.

Applications:

Suitable for cranes, excavators, stackers and reclaimers, port machinery, wind turbines, amusement rides, and other applications

Single-row ball slewing bearings Advantages

Full Load Capacity:
The single-row ball slewing bearing is designed to handle combined loads efficiently. Uniformly distributed steel balls ensure smooth and precise 360° rotation, enhancing operational accuracy and efficiency.

Durable and Reliable:
Manufactured with high-quality materials and advanced production technology, LTZC bearings deliver long service life and stable performance under demanding conditions.

Multiple Mounting Options:
Available in internal gear, external gear, and non-gear types, providing flexibility for different installation requirements.

Low Maintenance Cost:
Optimized sealing and lubrication systems minimize downtime and reduce overall maintenance costs, ensuring long-term reliable operation.
