Slewing Bearing

Slewing bearings, also known as slewing rings or turntable bearings, are large-diameter bearings that allow for rotational movement between two structures. They are designed to support axial, radial, and moment loads also with impact design, making them essential in applications where space is limited. Slewing bearings are generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main machine design structure is compact, the guidance is simple, and the maintenance is easy. ZMS is a professional slewing bearing supplier in China. The factory use premium material in China and the roller and rings precision are high. No matter you need standard or non standard slewing bearing, we both can supply. Main series:

  • Single- row crossed roller series
  • Single- row four point contact ball series
  • Double-row eight point contact ball bearings series
  • Double- row ball series
  • Roller and ball combination series
  • Three-row roller series

High Load Capacity

Slewing bearings are designed to support significant axial, radial, and moment loads, making them suitable for heavy machinery and equipment.

Rotational Movement

They allow for smooth and controlled rotational movement between two structures, which is essential in applications like cranes and excavators.

Compact Design

Slewing bearings have a large outer diameter relative to their thickness, allowing for a compact design that saves space in machinery.

Versatile Configurations

Available in various designs (e.g., single row, double row, crossed roller, three-row roller) to meet specific application requirements and load conditions.

Integrated Gear Options

Some slewing bearings come with integrated gears, allowing for direct connection to drive systems, which simplifies installation and reduces the need for additional components.

Sealing Options

Many slewing bearings feature seals to protect against dirt, dust, and moisture, enhancing their reliability and performance in challenging environments.
