Technical Specifications

Structural Design and Working Principle

The bearing utilizes round and hollow rollers orchestrated in a exact 90-degree cross arrangement inside V-shaped raceways. This orthogonal course of action permits rotating rollers to handle loads from opposite bearings. Each roller keeps up partition through exactness spacers, anticipating coordinate contact and guaranteeing uniform stack distribution.

The coordinates ring structure dispenses with the complexity of split-ring gatherings. Pre-drilled mounting gaps empower coordinate connection to apparatus without extra lodging components. This plan diminishes get together time and dispenses with arrangement mistakes common in conventional bearing installations.

The UU assignment shows contact seals on both sides. These elastic seals hold factory-applied lithium oil whereas anticipating clean and contaminant entrance. This fixed arrangement expands bearing life in mechanical situations without requiring outside fixing systems.

Performance Advantages

Multi-Directional Stack Dealing with: The cross-roller course of action gives uncommon unbending nature against spiral, pivotal, and minute loads at the same time. This kills the require for different bearing courses of action in compact applications.

Superior Exactness: Fabricating accuracy to ISO P5 or higher benchmarks guarantees rotational runout regularly underneath 5 microns. This exactness level bolsters accuracy situating necessities in robotized equipment.

Compact Integration: The indispensably plan decreases hub space prerequisites by 30-40% compared to ordinary bearing courses of action. This space productivity demonstrates basic in mechanical joints and restorative instruments.

Low Contact Operation: Round and hollow roller contact minimizes rolling grinding compared to ball orientation. The optimized roller geometry decreases warm era amid operation.

Installation Effortlessness: Pre-drilled mounting gaps and fundamentally rings dispense with complex lodging machining. This plan decreases gathering mistakes and abbreviates machine construct times.

Primary Applications

Industrial Mechanical technology: Joint gatherings in 6-axis robots advantage from the bearing's minute stack capacity. The compact plan permits empty shaft setups for cable directing whereas keeping up situating precision beneath changing payloads.

Precision Fabricating Gear: CNC revolving tables and ordering components utilize the bearing's tall rotational exactness. The fixed plan anticipates coolant defilement whereas keeping up smooth ordering motion.

Medical Gadgets: Surgical mechanical frameworks utilize these heading in instrument situating components. The fixed setup anticipates defilement in sterile situations whereas empowering exact development control.
