Kavitsu Robotronix manufactures high-precision Slew Bearings (Slewing Bearings) for heavy-duty industrial machines. Over 30 years of manufacturing experience – ISO/DIN compliant – with worldwide export.
Slew Bearing / Slewing Bearing – Kavitsu Robotronix Pvt. Ltd.
A Slew Bearing – also known as a Slewing Bearing, Slew Ring Bearing, Turntable Bearing or Swing Bearing – is a large-diameter rolling element bearing designed for use in heavy-duty industrial machines.
As an experienced Slew Bearing manufacturer and exporter, Kavitsu Robotronix offers slew bearings in various configurations for diverse industrial applications. Our bearings are engineered to carry axial, radial and moment loads simultaneously – ideal wherever precise rotation under heavy load is required.
We supply ISO/DIN standard slew bearings for global markets – as off-the-shelf products or custom-engineered solutions from 100 mm to 4000 mm bore diameter.
Kavitsu offers Slew Bearings in three main design types – the right solution for every load requirement and application.
Compact design for light to medium loads. Ideal for solar tracking systems, conveyor belts and light construction machinery. Available with internal gear, external gear or no gear.
Higher load capacity through two rows of balls. Suitable for medium to heavy applications such as cranes, material handling systems and large medical equipment.
Maximum load capacity through three separate roller rows for axial, radial and tilting moment loads. Used in large cranes, mining equipment, wind turbines and offshore installations.
Simultaneous support of axial, radial and moment loads under the most demanding operating conditions.
Space-saving ring design for optimum space utilisation without compromising structural stability.
Low friction and low-backlash guidance for accurate positioning in heavy-duty machinery.
42CrMo alloy steel and stainless steel options for maximum strength and long service life.
Double-lip seals against dust, water and contaminants – extended service life in harsh environments.
Internal gear, external gear or no gear – tailored to your specific application requirements.
