Cross Shaft Universal Coupling

Cross Shaft Universal Coupling

Connects two shafts not in a straight line. Used in rolling mills, mining equipment, cranes. Transmits torque, compensates angle misalignment.

Product Introduction

The Cross Shaft Universal Coupling connects two shafts that are not aligned on the same axis, enabling power transmission at large angles (15°–25° for the SWC type) with an efficiency of 98%–99.9%. Its core components are manufactured from high-quality alloy steel and heat-treated for enhanced strength, ensuring high load-bearing capacity and smooth operation. Cross shaft universal couplings can be customized to specific requirements and are packaged in wooden crates to ensure safe delivery.

FAQ

 

Q: How often to add grease?

A: Every 3 months of running time with lithium grease. For continuous heavy load, shorten to 2 months.

Q: How to choose between SWC and SWP?

A: If misalignment angle over 10°, pick SWC. If angle under 10° but higher torque needed, pick SWP. Tell us your motor power and speed – we calculate the torque.

Q: Can worn fork be replaced?

A: Yes. Fork, cross shaft, bearings – all have separate spare parts. Delivery 15-20 days.
