Brif introductions of interinal gear bearing 133.25.500

Slewing ring bearings can accommodate axial, radial and moment loads acting single or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer ring are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearing can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gears. Following the drawing of customers' design.

There are ball bearing, roller bearing and ball-roller bearing at type; There are single-row, double-row and three-row at structure. With teeth and without teeth on conduction(outer or inner ring); At dustproof and leak grease proof type, with airproof and without airproof. At mounting with flanged(outer or inner ring), with bolt hole and without flanged.

Series of slewing bearing

RK series slewing ring bearings
These pre-engineered light profile slewing ring bearings offer high performance and reduced weight due to an optimized geometry that handles a combination of moment and thrust loads. Ideal for foundry shakeout tables, palletizers, wire winders, cable reels, welding tables and turntable applications where intermittent rotation and low velocity are present.

KH series slewing ring bearings
KH series heavy duty slewing rings are designed to provide precise positioning with consistent repeatability, in applications where rotation is constant, intermittent or oscillating. They are the ideal bearing for advanced rotary index tables or any design where the bearing will interface with other precision mechanical components.

HS series slewing ring bearings
HS series pre-engineered, light profile slewing rings feature rectangular cross sections, which allow for alternate hole patterns, improve stiffness, and the potential for more capacity. Ideal for cranes, aerial lifts, digger derricks, chute swivels, lift truck rotators, and industrial turntables.

HT series slewing ring bearings
HT series slewing rings are larger versions of the HS series, with increased ball diameter and cross-sectional area providing substantially more capacity. The internal configuration consists of deep groove gothic arch raceways and maximum ball complement, resulting in a four-point contact bearing that provides exceptional moment, thrust, and radial load capacities. Ideal for medium to heavy duty applications including cranes, aerial lifts, digger derricks, chute swivels, lift truck rotators, and industrial turntables.

XT series slewing ring bearings
XT series slewing ring bearings are custom designed with a rectangular cross section, and are available in sizes up to 218 inches OD (5500 mm). They are well suited for a wide range of applications where our standard product series do not meet demanding size, capacity, or weight requirements, including cranes, aerial lifts, excavators, wind turbines, utility derricks, log loaders and fellers, and feller heads.

DT series slewing ring bearings
The DT series consists of the eight-point ball bearing that originally developed to provide maximum load capacity for given envelope and bolt circle diameters. It provides an up to 80% increase in capacity over that of a single row four-point design, yet has a smaller profile than a three-row roller design and provides exceptional moment, radial, and thrust load capacities. DT series bearings have been used successfully in heavy duty applications including large excavators, large cranes, mining equipment, wind turbines, and telescopes.

XR series slewing ring bearings
The XR series consists of cross roller bearings, which provide a high degree of stiffness and low rotational torque within a minimal envelope. Consider this design when a four-point contact ball bearing does not meet the operating performance requirements for torque and stiffness. XR series roller bearings have been used successfully in applications requiring extra stiffness with a low torque requirement, including radar, military turrets, machine tools, and excavators.

TR series slewing ring bearings
The TR series consists of three-row roller bearings, offering the highest capacity for a given diameter. When an XR or DT series bearing doesn't meet your stiffness and capacity requirements, consider the TR series. TR series roller bearings optimize capacity, provide low frictional resistance and minimize deflection. TR series roller bearings have been used successfully in heavy duty applications requiring extra stiffness and capacity, including radar, cranes, excavators, stackers and reclaimers, and heavy mill equipment.
