Large diameter slewing bearings, Slewing Ring Bearings customized

Slewing Bearing is a kind of large bearing that can withstand large axial load, radial load and overturning moment and other comprehensive loads. This type of bearing generally has mounting holes, lubricating oil holes, sealing devices, internal gears or external gears, so It can make the main engine compact, easy to rotate, easy to install and easy to maintain. The slewing bearing has Four-point Contact ball bearings without gear, external gear and internal gear, double disc Angular Contact Thrust ball bearings, crossed Cylindrical roller bearings, Crossed Tapered Roller Bearings and three-row cylindrical roller Combined bearings and other structural types. Four-point contact ball bearings have high static load capacity, crossed cylindrical roller bearings have high dynamic load capacity, and crossed tapered roller bearings have high dynamic load capacity. It has larger support rigidity and higher rotation accuracy.

crane slewing bearing

crane Slewing Bearing, also known as a crane slew ring or crane turntable bearing, is a large bearing that allows the crane to rotate or slew. It is usually located at the base of the crane and supports the load-bearing structure of the crane. The crane slewing bearing enables th

slewing bearing gear

Slewing Bearing gear, also known as a slewing ring gear or external gear, is an integral component of a slewing bearing. It is a ring-shaped gear that is typically located on the outer circumference of the bearing. The gear teeth are designed to mesh with a mating gear or pinion,

slewing bearing internal gear

slewing bearing with an internal gear, also referred to as an internal gear slewing bearing or internal gear slew ring, is a type of bearing that incorporates a gear with teeth on the inner circumference of the bearing. This internal gear meshes with a mating pinion or gear to tr
