Kavitsu Robotronix – a trusted Slew Ring Bearing manufacturer supplying high-precision slewing rings for cranes, wind turbines, solar trackers and offshore equipment. ISO/DIN compliant, bore 100–4000 mm. Exported worldwide.
Slew Ring Bearing / Slewing Ring – Kavitsu Robotronix Pvt. Ltd.
A Slew Ring Bearing – also known as a Slewing Ring, Slewing Bearing, Turntable Bearing or Swing Bearing – is a large-diameter rolling element bearing designed to support axial, radial and moment loads simultaneously while enabling 360° rotation.
As a leading Slew Ring Bearing manufacturer, Kavitsu Robotronix has been supplying precision slewing rings for over 30 years. Our bearings are engineered for the most demanding industrial applications – from tower cranes and wind turbines to offshore drilling rigs and solar tracking systems.
We manufacture Slew Ring Bearings from 100 mm to 4000 mm bore diameter in standard and custom configurations, with options for internal gear, external gear or gearless designs, to ISO and DIN standards.
Engineered for extreme reliability – our Slew Ring Bearings deliver outstanding performance in the most demanding industrial environments.
Simultaneous support of axial, radial and tilting moment loads in a single compact unit.
Smooth, continuous rotation under heavy load for precise positioning in all industrial applications.
High-strength alloy steel with induction or furnace hardening for maximum durability and fatigue resistance.
Robust seals against dust, moisture and contaminants – extended bearing life in harsh environments.
Available with internal gear, external gear or no gear – to match any drive system and mounting arrangement.
Fully customisable bore size, gear module, mounting holes and surface treatment to your specifications.
