Technical Features
Low Friction Design
Open flange design with optimized roller end geometry promotes lubricant film formation, reducing friction while increasing axial load capacity.
Extended Service Life
Logarithmic roller profile minimizes edge stresses at roller/raceway contact points, enhancing durability and tolerance to misalignment.
Operational Reliability
Precision surface finishing on contact surfaces supports stable hydrodynamic lubricant film formation.
Modular Design
Separable components are fully interchangeable, simplifying installation, removal, and maintenance procedures.
High-Speed Capability
Advanced cage designs accommodate high rotational speeds, rapid acceleration cycles, and peak loading conditions.
