excavator swing bearing

The slewing bearing of the crane is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time. This product supports customization, and various slewing bearings with special structures can be designed, developed and produced according to user needs.

The double-row ball gearless slewing bearing is an important mechanical component. Its design feature is that it has two rows of steel balls, which can withstand large axial forces and tipping moments. This product is particularly suitable for medium and large diameter tower cranes, truck cranes and other loading and unloading machinery.

The three-row roller large slewing bearing is a high-performance bearing product designed to withstand large oil loads, overturning moments and radial loads. Its processing technology is complex but sophisticated, usually including material selection, forging, heat treatment, finishing and surface mounting.

Customizable steel slewing bearing is a high-precision, high-load-bearing mechanical component widely used in engineering machinery, metallurgical machinery, medical machinery and other fields. This product supports customization according to customer specific needs, including size, material, load-bearing capacity and other aspects to meet the needs of different equipment.

This large single row ball slewing bearing has become the first choice for many high-end machinery and equipment fields due to its exquisite craftsmanship, excellent performance and exquisite appearance treatment. It is widely used in important industries such as hoisting machinery, port machinery, and wind power generation. Contribute to promoting technological progress and development in related fields.

We provide customizable special-shaped slewing bearings, which are tailored to meet the specific needs of different mechanical equipment. Our special-shaped slewing bearings have the characteristics of high precision, high load capacity and low friction coefficient, ensuring the stable operation of the equipment in complex environments.

In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings.
