Key Features & Technical Specifications
- High Load Capacity: Designed to handle both axial and radial loads, the four-point contact ball design distributes stress evenly, supporting dynamic loads up to 2000 kN.
- 360° Continuous Rotation: Precision-machined raceways and hardened steel balls ensure smooth, low-friction rotation, even under heavy loads and high-speed swing cycles.
- Bolt Hole Mounting: Factory-drilled bolt holes (through or blind) simplify installation onto the excavator chassis and turret, eliminating the need for field drilling and reducing downtime.
- Durable Materials: Manufactured from high-strength alloy steel (42CrMo, 50Mn) with induction-hardened raceways, offering excellent wear resistance and long service life.
- Sealing Options: Available with rubber seals, metal shields, or labyrinth seals to protect against dust, moisture, and debris commonly found in construction sites.
- Gear Options: Optional internal or external gear teeth can be integrated for direct drive or pinion engagement, supporting various swing drive configurations.
- Customizable Dimensions: Inner diameter from 500 mm to 2000 mm, outer diameter from 600 mm to 2500 mm, and height from 50 mm to 200 mm – all customizable to match your excavator model.
- Quality Assurance: Each bearing undergoes 100% non-destructive testing (ultrasonic, magnetic particle) and dimensional inspection to ensure compliance with international standards.
