Ball Cage Constant Velocity Couplings

Overview

Our Ball Cage CV Couplings provide smooth, constant-speed power transmission, even at high operating angles. They are available in Fixed (BJ) and Sliding (DOJ, BOS, etc.) types to fit different installation needs.

Key Specs

· Angle: Up to 75°

· Torque: 380 – 1,000,000 N·m

· Size: Diameter Φ36 – Φ725 mm

· Options: Overload protection available upon request.

Key Advantages

· Zero Speed Fluctuation: Guarantees synchronous rotation of input and output shafts, protecting downstream equipment from harmful torsional vibrations.

· High Efficiency: Precision-ground ball tracks minimize friction, resulting in transmission efficiencies consistently over 98%.

· Compact & Balanced: The high-strength, space-saving design allows for high-speed operation with excellent dynamic balance, significantly reducing noise and wear.

· Shock Absorption: Naturally absorbs impact and vibration, extending the service life of motors, gearboxes, and connected machinery.

Typical Applications

These couplings are mission-critical in industries where precision and durability are paramount:

· Metallurgical Equipment: Essential for roller drives in Tension Levelers, Flying Shears, and Side Trimmers where high torque and angular misalignment occur simultaneously.

· Heavy Machinery: Used in the drivelines of construction, mining, and agricultural equipment.

· Industrial Automation: Ideal for precision indexing tables, robotics, and high-speed test benches.
