Also known as turntable bearings, slewing bearings are large-scale precision special bearings integrating supporting, rotating, load-bearing and transmission functions. They can withstand axial loads, radial loads and overturning moments simultaneously with highly integrated structures and comprehensive load-bearing performance. Featuring high rigidity, heavy load resistance, impact resistance and low maintenance, they are widely applied in construction machinery, wind power equipment, automatic rotary tables, lifting machinery and intelligent equipment, serving as the core load-bearing key components of various rotating devices.

The integrated structure is the core feature of slewing bearings. Composed of inner and outer races, rolling elements, spacers and sealing systems in an integrated design, the product is equipped with standard mounting holes, requiring no additional base processing. It greatly simplifies equipment structural design and reduces assembly difficulty and manufacturing costs. Available in gearless, external gear and internal gear types, it can directly cooperate with driving mechanisms to realize rotary transmission, integrating support and transmission functions to adapt to various industrial working conditions of low-speed, heavy-load and continuous rotation.

With clear load classification, the product boasts strong adaptability to full working conditions. The four-point contact ball type features low friction resistance and flexible rotation, suitable for medium and light-load high-frequency rotating automated equipment and small construction machinery. The cross roller type adopts staggered roller arrangement with higher rigidity, smaller clearance and excellent positioning accuracy, ideal for high-precision scenarios such as precision rotary tables, robots and testing equipment. The three-row roller type has a large bearing area with layered load sharing, outstanding impact and deformation resistance, meeting the harsh heavy-load working conditions of cranes, excavators and wind power main units.

High-strength materials and precise heat treatment ensure long service life. Slewing bearings are integrally forged from high-strength alloy steel, and their raceways undergo deep quenching and hardening treatment with uniform hardness and excellent wear and corrosion resistance. They can withstand long-term alternating loads and impact loads without pitting, spalling or deformation. Equipped with high-quality spacer structures to avoid friction and collision between rolling elements, the bearings operate stably with low noise and no jitter or displacement.

All models are fitted with multiple sealing protection structures and convenient lubrication systems, which effectively block dust, sediment, moisture and rainwater from invading the raceways, adapting to complex harsh environments such as outdoor construction, mines, construction sites and coastal areas. Standard lubrication holes are reserved for regular grease replenishment to maintain a stable lubrication state. With stable precision, sufficient rigidity and low failure rate, slewing bearings have become indispensable core precision accessories for heavy-load rotating equipment relying on comprehensive and reliable performance.
