Main Products
Core Coupling Products
Four core coupling solutions for pumps, fans, rolling mills, lifting equipment and other industrial transmission systems.
Disc Couplings
Flexible metal disc packs transmit torque without lubrication while accommodating axial, angular and parallel misalignment in high-speed, precision drive systems.
Universal Joint Shafts
Double-Cardan universal joint shafts transmit high torque between misaligned shafts and accommodate angular movement in rolling mills and heavy machinery.
Drum Gear Couplings
Heavy-duty drum gear couplings transmit high torque while allowing angular displacement, making them ideal for crane hoists, lifting drums and metallurgical equipment.
Elastic Sleeve Pin Couplings
Elastomer sleeves on the pins absorb shock and vibration while compensating for small shaft misalignment in pumps, fans and general industrial drives.

Global SupportCall To Action / RFQ
Send drawings, shaft sizes or coupling photos. We will help narrow the right solution.
For overseas buyers, a clear RFQ path reduces back-and-forth and helps us check product type, bore, torque, material and lead time faster.
- Replacement coupling photos, old model number or broken part dimensions
- OEM drawings, bore/keyway size, torque, speed and operating environment
- Quantity, target delivery schedule and packing requirements
