Construction industry

Load Support & Rotational Motion

Tower cranes, slewing rings, and concrete pump trucks rely on high-load bearings to perform smooth lifting and turning.

Recommended Models: 22222CA/W33, 22318CC/W33, Slewing Bearing Series

Shock Absorption & Vibration Damping

Heavy-vibration equipment like tamping machines and mixers require bearings with strong impact and vibration resistance.

Recommended Models: UC208, UC211, GE60ES Spherical Plain Bearings

Positioning & Load Guidance

In crawler excavators and concrete distribution booms, bearings guide motion and distribute load precisely.

Recommended Models: NU2207E, NJ2310E, NKI25/20 Needle Roller Bearings

Sealing & Anti-Contamination

Construction sites expose bearings to fine dust and slurry. JRZC offers enhanced sealing structures (double-lip seals, labyrinth seals, mud covers).

Typical Models: UCFL205, UC209, 6205-2RS

Quick Installation & Modular Maintenance

To meet tight project timelines, pre-assembled bearing units simplify mounting and reduce downtime.

Recommended Models: UCP206, UCT208, Adapter Sleeve Mounted Series

Corrosion-Resistant Materials: Withstand humidity, mud, and outdoor exposure

Optimized Roller Design: For greater load rating and operational stability

System Compatibility: Fit seamlessly with hydraulic drives, gearboxes, and track systems

Long-Life Lubrication: Some models sealed with lifetime grease, minimizing maintenance

Customizable Solutions: Tailored for specific size, load, and operational demands

JRZC bearings are widely used by tower crane OEMs, concrete batching plants, and excavator factories
