VI 603280N -VI VSI Bearings

The VI and VSI series are standard single-row four-point contact ball slewing bearings with internal gear, widely adopted for light to medium-duty rotary machinery worldwide. Featuring a compact monolithic structure, optimized gothic arch raceway and integrated internal gear design, these slewing rings deliver reliable load capacity, precise rotation and outstanding cost performance, making them a mainstream solution for general industrial and mobile equipment rotary drive systems.


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

✦ Internal gear on inner ring – Gear teeth cut on the inner ring for compact drive integration and direct pinion engagement.

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

✦ High-precision design – Manufactured to tight tolerances for precise 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.
