Heavy-Duty Slewing Bearing – Ultimate Durability for Construction & Mining Machinery

Our heavy-duty slewing bearing (also known as slewing ring or turntable bearing) is professionally engineered to handle extreme combined loads, including axial load, radial load, and heavy tilting moment, serving as the core rotating component for all kinds of large rotary machinery. Different from ordinary bearings that only adapt to single load and high-speed operation, our slewing bearings are uniquely designed for low-speed, high-torque, and frequent oscillating rotation, perfectly matching the working characteristics of engineering equipment.

Manufactured with premium forged steel and integrated heat treatment technology, our slew bearings feature high structural rigidity, strong impact resistance, and excellent deformation resistance. The precision-machined raceway ensures smooth and stable rotation without jitter or noise even under long-term heavy-load operation. Equipped with multi-layer comprehensive sealing structures, the bearings effectively block dust, mud, water, and corrosive particles, completely adapting to harsh working scenarios such as construction sites, mining yards, and road engineering.

We provide a full range of standard models with outer diameters from 50mm to 10000mm, covering single-row ball, double-row ball, single-row cross roller, and triple-row roller structures. All products come with pre-reserved mounting holes and lubrication holes, realizing quick installation and convenient daily maintenance, which greatly reduces equipment downtime and after-sales costs.

Key Advantages

• Super load capacity: Supports three-dimensional combined loads to stabilize equipment operation
• Harsh environment resistance: Dustproof, waterproof, wear-resistant and anti-corrosive
• Durable performance: Strict heat treatment process extends service life by 30%+
• Easy installation & low maintenance: Optimized structural design saves labor and time costs

Wide Applications: Excavators, cranes, loaders, aerial work platforms, mining machinery, road construction equipment, port handling machinery
