Series 23 25 28

Series 23 25 28

Series 23 25 28 series slewing ring bearings provide a wide variety of solutions for applications where a large diameter and lighter weight are key.

Their slimmer and lighter yet robust design is ideal for standard applications. They are available in 3 preload ranges, and are suitable for a wide range of applications, providing an efficient and reliable solution at an optimised cost. Our LIGHT SERIES slewing rings are used for turntables or light load handling systems.

Four Point Contact Ball Slewing Ring Bearing

HS series pre-engineered, light profile slewing rings feature rectangular cross sections, which allow for alternate hole patterns, improved 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 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

MT slewing bearings provide optimal economy and capacity for a given envelope dimension. MT series heavy duty bearings are an economical replacement for kingpost designs and utilize the same four-point contact design concept as our heavier duty slewing bearings, providing exceptional moment, thrust, and radial load capacities. Ideally suited for applications such as truck mounted cranes, hoists, and non-precision industrial tables and positioners.

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.

XT series slewing 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.

Eight Point Contact Ball Slewing Ring Bearing

The DT series consists of the eight-point ball bearing that Kaydon 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, thrust, and radial load capacities. DT series bearings have been used successfully in heavy duty applications including large excavators, large cranes,

The 4000 series include lower frictional torque and the ability to function in mounting structures with less accuracy and rigidity

Series 01 slewing bearings have lower frictional torque and the ability to function in mounting structures with less accuracy and rigidity.

Series 09 series features the eight-point ball bearings LILY developed to provide maximum load capacity for given envelope and bolt circle diameters.

Cross Roller Slewing Ring Bearing

The XR series consists of Kaydon 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.

Three-Row Cross Roller Slewing Ring Bearing

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 reclaimer

Series 30 slewing rings provide a cost-effective solution for applications requiring low-speed, bi-directional rotation of light loads.

Thrust Ball Slewing Rings

Thrust is transmitted at a 90° contact angle, thus making the most efficient use of the slewing ring capacity.

Combination Slewing Rings

This Series is destined for applications with small ecen-tricities at relatively high axial loads,which call for a long service life even with continuous oscillating motions,and where the structural design requires a large bearing diameter.
