Description

Design Principle: The three rows of rollers bear axial,radial,and overturning moments respectively. Through the independent raceway design,the load is separated,reducing internal stress concentration. Performance Features: Compound load-bearing capacity: Capable of simultaneously withstanding axial,radial,and moment loads.-High-rigidity structure: The three-row roller layout improves the anti-deformation ability. Long-service-life design: Hardened raceways (HRC55-62) enhance wear resistance.

Features

Optimized compound load

No additional bearing combinations are required,simplifying the mechanical structure.

High reliability

Adaptable to harsh working conditions (dust,vibration,impact).

Easy installation

Standardized interfaces are suitable for a variety of equipment.

Economical maintenance

Long-acting lubrication design reduces downtime.

Working Principle

Load Transfer Mechanism: Axial load: Directly borne by the upper and lower rows of rollers. Radial load: Evenly distributed by the middle row of rollers. Overturning moment: Transferred through the diagonal contact of the three rows of rollers. Lubrication and Sealing: Grease lubrication: Lithium-based grease (-20°C ~ 120°C). Oil lubrication: Circulation system for high-speed and heavy-load scenarios. Sealing structure: Double lip-type seal (RS + ZZ) to protect against contaminants.
