Ball-Cage Universal Coupling for Heavy-Duty Petroleum Applications

The ball-cage universal coupling combines advanced design with reliable performance:
• Provides damping and vibration reduction, effectively lowering noise, with an automatic recirculating lubrication system.

• Offers 0.5 to 1 times higher load capacity compared to conventional universal couplings with the same rotation diameter and inclination angle.

• Ensures excellent synchronization between driving and driven shafts, even when using a single ball plunger type structure.

• Allows large axial and radial displacement compensation; axial displacement can be achieved without external spline connections.

• Compact and lightweight structure with high manufacturability, supporting efficient mass production and reduced costs.

• Reliable in operation, easy to assemble and disassemble, convenient to maintain, and delivers long service life.

• Applicable to a wide range of working conditions, from low speed heavy loads to high speed drives, particularly effective for shafts with large inclination angles or restricted radial dimensions.

• Allows significant axial and radial displacement, with a large angular misalignment capacity, eliminating the need for external spline connections in axial movement.
