SKF Bearing Type : Slewing BearingsIndonesia Industrial Parts

Slewing bearings

Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

SKF manufactures standard and customized slewing bearings in various designs, with outside diameters from 0,1 to 18 m to meet the demands of particular applications.

Slewing bearing with four-point contact ball bearing

Optimal economy and capacity for given dimensions, or when replacing existing multi-bearing arrangements.

Slewing bearing with eight-point contact ball bearing

80% increase in capacity compared to a same-sized single row four-point contact ball bearings.

Slewing bearing with crossed cylindrical roller bearing

High stiffness and constant resistance to rotation.

Slewing bearing with triple row roller bearing

Provide highest capacity for a given diameter.

Slewing bearing with wire race bearing

60% lighter compared to same-sized all-steel bearings.

Customized slewing bearing

SKF has extensive experience in designing and manufacturing customized or special slewing bearings, for example, slewing bearing with combined roller/ball bearing (as shown), with segmented bearing or with inserted raceways bearing.

Features and benefits

Depending on their design, slewing bearings have the following features:

High load carrying capacity
High stiffness for rigid bearing application
Low friction
Long service life
Surface protection and corrosion resistance
Integration of additional features, including:
- Driving mechanism
- Control devices
- Lubrication systems
- Monitoring systems
- Sealing cassettes

Application of SKF Bearing Type : Slewing Bearings

Slewing bearings are used in a variety of industries and applications, including:

Construction: Used in cranes, excavators, and other heavy equipment to allow rotation of the top of the machine.
Renewable Energy: Applied to wind turbines to allow orientation of the blades against the wind direction.
Medical Equipment: Used in diagnostic equipment such as CT and MRI scanners to enable precision movement.
Robotics: Enables high-precision rotation of robot joints.
