Custom & Standard Slewing Bearings

Premium Industrial Slewing Bearings for Harsh Conditions

Slewing bearings are core load-bearing rotary components for heavy machinery, supporting simultaneous axial, radial and tilting moment loads. Our industrial-grade slewing rings are optimized for heavy-load, dusty, humid and corrosive working environments, effectively solving common industry pain points including premature wear, oil leakage, rotation jitter and short service life. We deliver stable, low-maintenance and cost-effective bearing solutions for global industrial equipment.

We supply full-range standard and custom slewing bearings, including ball and roller types with single/double/triple row structures, available in internal gear, external gear and gearless designs. All products meet international industrial standards and are widely exported worldwide for construction, new energy, marine and environmental machinery.

Key Performance & Pain Point Solutions

• Long Service Life & Wear Resistance: Made of high-quality alloy steel with integral quenching and precision raceway grinding, featuring high hardness and strong fatigue resistance for long-term heavy-duty operation.
• Excellent Sealing Performance: Adopts multi-layer composite sealing structure, fully waterproof, dustproof and mud-proof to prevent grease leakage and dry friction, ideal for outdoor harsh working sites.
• Stable & Precise Rotation: Strict clearance control and optimized contact structure eliminate rotation jitter, ensuring high operational stability and equipment safety.
• Easy Installation & Good Compatibility: Standard unified dimensions and mounting holes. Custom sizes and gear parameters are available for special equipment matching.

Product Types & Application Scenarios

We classify our bearings by load capacity and precision to help you select the most suitable model efficiently:

1. Light-Duty Four-Point Contact Slewing Bearings

Compact, lightweight and cost-effective. Ideal for light-load, low-frequency rotation equipment such as aerial work platforms, solar trackers and small sanitation trucks. Multiple types in stock for fast delivery.

2. Medium-Duty Double Row Ball Slewing Bearings

Enhanced load capacity and anti-vibration performance. Perfect for medium-load frequently operated machinery including truck cranes, small excavators and port handling equipment.

3. High-Precision Cross Roller Slewing Bearings

Ultra-small clearance and high rigidity with precise positioning. Suitable for precision equipment like automated rotary platforms, robotic arms and medical machinery.

4. Super-Heavy Triple Row Roller Slewing Bearings

Super three-dimensional load-bearing capacity with strong impact resistance. Designed for ultra-heavy equipment such as large tower cranes, mining machinery and offshore engineering facilities.
