Load Capacity Axial rated load: 32 kN; Static allowable load: 58 kN; Friction coefficient: 0.001-0.003 (oil lubrication)
Structure and Core Functions
**Precise Positioning:** The ring structure with positioning steps limits the axial displacement of bearings or pins, suitable for components requiring precise axial positioning, such as rotary platforms and travel gearboxes.
Wear Resistance and Load Capacity: Made of 52100 bearing steel with integral quenching, offering strong resistance to pitting and deformation, suitable for low-to-medium speed and medium axial load conditions, extending component service life.
Assembly Compatibility: A simple, seal-groove-free design allows for assembly with standard thrust ball bearings, providing a compact installation space and suitable for batch maintenance scenarios, reducing assembly difficulty.
Load Transfer: The ring contact surface evenly transfers axial loads, avoiding localized stress concentration and protecting the mating surfaces of the bearing and related components.
Compatible Models and Application Scenarios
Compatible Equipment: CAT 305.5E2/306E2 mini excavators, 906M/907M loaders, 420F backhoe loaders, etc.
Core Applications: Used for positioning the upper and lower bearing rings of slewing bearings, the output shaft of travel motors, the piston positioning rings of hydraulic cylinders, and the axial retaining rings of the boom cylinder base, providing axial positioning and load support, suitable for medium-load and low-to-medium speed operating conditions.
