Slewing Bearing

Kavitsu Transmissions now offers high performance slewing bearings in a variety of ball and roller type designs. In case of ball type design, the company offers single row ball bearing slewing ring with four-point contact and double row ball bearing slewing rings with double axis system. In case of roller bearing design, it offers three roller bearing slewing rings with axial and radial roller type. Pre-heat treated high quality alloy steel is used for rings with final treatment with induction hardening. A perfect profile of rollers and ball seats is achieved with preliminary machining and finally by grinding with sophisticated state-of-the-art machines and special tooling developed in-house. A variety of range up to 3500 mm external diameter can be offered with either internal teeth or external teeth cut or without any teeth. The complete bearing is offered in pre-lubricated condition with grease nipples, high quality dust seals and standardised claming bolt pattern. These bearings give a normal life of 30000 revolutions on load. The selection of type of rolling element either ball or roller and the number of rows, is entirely based on an application and method of use, such as slewing over angle, operating cycle, oscillatory motion etc. Normally these bearings are used where a rotary motion is required without transmission of high radial load, rotation at slow speed and little rough application. The major fields in which these slewing bearing rings are used are: wind turbines, turntables, mobile cranes, excavators, port cranes, turn dish rotation in steel industry, work platforms and so on. Along with the slewing ring bearings, the company offers slewing gearboxes also. These are with pinion suitable to drive the slewing ring bearing. It can also manufacture custom built slewing bearing rings.
