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.
Industry Applications
Our couplings drive performance across diverse heavy-duty sectors.

Why Haowei
Why choose Haowei for precision coupling supply?
For overseas buyers, the real value is not only the coupling type. It is whether the part fits the shaft, matches the working torque and can be repeated reliably in future orders.
Precision Machining
Bore size, keyway, shaft tolerance and installation dimensions are checked around real machine fit.
Drawing-Based OEM
Custom hubs, sleeves and coupling bodies can be discussed from drawings, samples or application data.
Material Options
Steel, stainless steel, aluminum and elastomer elements are selected for torque, environment and service life.
Inspection Before Shipment
Key dimensions, surface condition and packing details are reviewed before delivery to reduce procurement risk.
Factory Video / Reality
Real workshop capability behind every coupling order.
Coupling buyers often need proof behind the quotation. Haowei supports clearer decisions with machining details, inspection focus and export packing information.

Call 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
