Slewing bearings (also called slewing rings, slewing ring bearings, slew bearings, slew rings, slew ring bearings, swing bearings, turntable bearings) are machine elements can carry all axial and radial forces, and tilting torques at the same time.
LYXQL can produce slewing bearings with outer diameter from 1500mm to 18000mm.
1. Three different gear types:
Single row ball slew bearings, are also called four point contact ball slew bearings, according to the gears types, single row slewing rings include non-gear types, external gear types, and internal gear types.
2. Component parts:
Four point contact ball slewing bearings with external gear are consisting of inner ring, outer teeth ring, balls, cage (or spacers) and sealings.
Inner rings for four point contact ball swing bearings with external gear have integral structure and split structure. Inner rings and outer teeth rings can be produced with chrome steel, alloy steel, stainless steel and other materials requested by customers.
Single row ball turntable bearings’ balls can be produced with chrome steel and stainless steel as per different working conditions.
Usually, single row ball slew bearings are assembled with cages (or spacing blocks), but sometimes full ball types will be available to carry larger load capacity. Cages or spacers can be produced with different materials as per different working temperature.
For sealing device, material can be used Teflon under high-temperature condition and nitrile rubber for usual working condition.
3. Application:
Single row ball slewing rings are usually used for slewing conveyers, welding arm and positioner, cranes, excavators and other engineering machines.
