Kavitsu Robotronix – leading Slewing Bearing manufacturer for cranes, wind turbines, mining and offshore applications. Also known as Slew Ring Bearing, Slew Bearing and Turntable Bearing. ISO/DIN compliant, bore 100–4000 mm. Exported worldwide.
Slewing Bearing / Slewing Ring – Kavitsu Robotronix Pvt. Ltd.
A Slewing Bearing is a large-diameter rolling element bearing that supports axial, radial and moment loads simultaneously while enabling smooth 360° rotation under heavy load. It is the critical pivot component in countless heavy-duty machines worldwide.
As a dedicated Slewing Bearing manufacturer, Kavitsu Robotronix has been engineering precision slewing bearings for over three decades. Our products serve the most demanding industrial sectors – from wind energy and offshore drilling to large crane systems and solar power plants.
We manufacture to ISO and DIN standards, offering bore diameters from 100 mm to 4000 mm in standard and fully custom configurations. Whether you need a single bearing or a long-term supply contract, Kavitsu delivers quality and reliability.
This bearing is known by many names across industries and regions – all referring to the same product:
Kavitsu Slewing Bearings are built for the harshest conditions – combining structural strength, precision and long service life.
Simultaneous handling of axial, radial and tilting moment loads in one compact rolling element unit.
Precision-ground raceways for low-friction, low-backlash rotation under full load.
High-grade steel with induction or furnace hardening for exceptional fatigue life and load-bearing capacity.
Double-lip seals in synthetic rubber protect against dust, water and grease escape in field conditions.
Internal, external or no gear – matched to your drive arrangement and pinion specifications.
Any bore size, bolt pattern, gear module and surface treatment – designed to your engineering drawings.
