Slewing Bearing

Slewing bearings are large bearings that can withstand large axial and radial loads and tipping moments. They are particularly suitable for applications that carry heavy loads and provide structural rotation.

Structural features

Round Design: Slewing ring bearings are usually large ring structures with inner and outer rings filled with rolling elements such as balls or rollers.

Rolling Elements: Spherical or cylindrical rollers can be distributed in specific tracks to support compound loads (axial, radial, and tipping moments).

Sealing Systems: To protect bearings from dust, water and other contaminants, they are often equipped with efficient sealing systems.

Gear System: Many slewing ring bearings are designed with internal or external teeth to facilitate rotation through the gear system.

Structure Type

Cross roller type 14 series
Four point contact ball Type Standard 20 series
Four Point Contact Ball Type Light 20 series
Four-point contact ball type P series

Application environment

Construction Machinery: Such as excavators, tower cranes, and mobile cranes, which need to withstand heavy loads and perform complex movements.

Wind power: The main bearing used in wind turbines allow the wind turbine to adjust according to the wind direction.

Medical Devices: Used in advanced medical imaging equipment such as CT scanners and radiotherapy equipment, which enables the device to be rotated precisely.

Military & Aerospace: Orientation adjustment systems for radars, tank turrets, and spacecraft.

Design features

Versatility: Able to handle many different types of loads at the same time, such as axial loads, radial loads, and tipping moments.

High-Load Carrying Capacity: Designed to withstand extremely high loads, suitable for heavy industrial and engineering applications.

Custom Design: Typically tailored to the needs of a specific application to meet specific size and load requirements.

Long-Term Durability: Highly wear-resistant materials and protective measures ensure long-term reliable operation in harsh environments.

Our engineers can solve your problems

Composite Load Management: Effectively deal with stress and wear caused by complex loads in multiple directions.

Space and Weight Savings: In applications that require large bearings, multiple load handling problems can be solved with a single bearing, saving space and weight.

Precise Control of Motion: Provides smooth and precise rotational motion, which is especially important for precision equipment and instruments.

Reduced Maintenance: Design considerations and sealing systems reduce maintenance requirements and overall operating costs
