KSR BEARINGS is a modern-day manufacturer of India experienced in the field of heavy Engineering since 1979 for large-sized Slew bearings, Segmented bearings , Gear Rings , Pinions & Shafts.
We have been serving industries like coal mining, steel production , power generation, cement plant, water treatment plant, defence sector, mineral processing, Robotics, Forging & metal Industry, atomic energy, industrial automation, chemical & Fertilizers manufacturing.
Our company policy is to deliver uncompromising high quality products without any defects making sure efficient production & timely delivery as a priority at justified price with flexible payment terms. All our products come with a standard 2 year warranty ensuring full customer satisfaction.
Working under strict guidelines towards a Green World we do understand our responsibility in terms of Energy efficiency, Plastic recycling, Water conservation, Pollution & Waste management Necessitating us to obtain Environmental Management Systems certificate.
We have a wide range of slew ring bearings to choose from. Depending on your application, we can manufacture these bearings in various designs and dimensions, generally in seamless forged rings made of material 42 Crmo4 . Operations such as turning, milling, drilling, and gear cutting are done on CNC machines to work within the tightest tolerances. The induction hardening and grinding procedure ensure the longevity of the rings.

Large diameter slew bearings are mainly used in tunnel boring machines in the construction industry. The roller bearing slewing rings for this industry comes with unique sealing systems owing to higher dust exposure.
The application opportunities of slewing bearings range from cranes to road transport and drilling rigs. KSR bearings have been tried and tested in the harshest environmental conditions, in a wide temperature range, ranging from -50°C to +80°C and under the strictest mechanical loads in any environment.
Our slewing bearings prove themselves in diverse application areas day in, day out. The hard-wearing materials enable optimum use in harshest environmental conditions, making these exceptionally well suited for the energy industry.
KSR slew ring bearings are used in fast-erecting wind turbines. Depending on the size and design, four-point bearings, roller bearing slewing drives, or special bearings are used for the rotor blade and yaw adjustment.
The application opportunities of slewing bearings range from cranes to drilling rig cranes. KSR bearings have been tried and tested in dusty conditions and under the strictest mechanical loads in any environment.
Our slewing bearings find use in mobile, fast-erecting, mobile, and crawler cranes. Depending on the size and design, Ball and roller bearing slewing drives or special bearings are used for various motion types.
Our roller bearing slewing rings with bolt connection or bayonet connection are available for unique adjacent structures used in the Excavator Industry. For deep digging, dusty applications are special; multi-level sealing packages are also possible.
Roller-bearing slewing rings by KSR are supplied in all teeth versions, which have typical mining excavators or large crawler cranes.
KSR roller-bearing slewing rings are suitable for medium to high loads. Our slewing bearings are designed in a triple-row model with two axial and one radial roller raceway as standard. Still, other designs and variants are also possible depending on the application in the construction industry.
The linear load transfer allows them to transfer much higher forces in the same installation space than four-point bearings and makes them particularly suitable for larger diameters. Roller-bearing slewing rings are distinguished by a high power density but tend to place higher demands on adjacent structures' stiffness.
