VSU200744 -VU VSU Slewing ring bearing

VU and VSU series slewing bearings are premium gearless four-point contact ball slewing rings engineered for flexible, low-torque rotary applications. Removing traditional internal and external gear structures, these bearing models focus on universal adaptability and smooth pure rotary motion. Designed for light to medium-duty industrial machinery, the VU and VSU series combine compact mechanical geometry, outstanding multi-directional load capacity and minimal rotational resistance, offering an ideal non-geared rotary solution for custom drive system designs.


Typical Applications

Radar and antenna positioning systems

Precision rotary tables and indexing equipment

Medical equipment such as CT scanners and radiotherapy devices

Solar tracking systems requiring high pointing accuracy

Robotics and automation equipment


High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)

Characteristics

✦ No gear teeth – Smooth inner and outer rings without teeth for flexible drive integration.

✦ Four-point ball contact – Single-row design handles axial, radial, and tilting moment loads simultaneously.

✦ High-precision design – Manufactured to tight tolerances for accurate positioning and smooth rotation.

✦ Induction-hardened raceways – Rolling surfaces hardened for wear resistance and extended service life.

✦ Double lip seals – Fitted with NBR seals on both sides to keep contaminants out and retain lubricant.

✦ Pre-drilled mounting holes – Both rings feature equispaced bolt holes for quick and secure installation.
