Jaw, rigid, flange, bellows & disc couplings machined to exact bore, keyway and tolerance specs. Prototype in 3–5 days. No MOQ. Factory-direct pricing.
Pain Points
Getting custom couplings right shouldn't be this hard. Here's what buyers tell us before they switch to Chiheng.
Custom couplings from US or European shops often cost 3–5× more than they should. We offer factory-direct pricing with the same — or better — precision, saving buyers 30–50% per order without compromising on tolerance or material spec.
Long lead times kill project momentum. Our dedicated rapid-response team delivers prototypes in 3–5 business days and production runs in 7–15 days — so your engineering schedule stays on track, not on hold.
Most factories won't touch orders under 50 or 100 pieces. We have no minimum order quantity — whether you need 1 prototype for R&D validation or 5,000 pieces for a production run, our pricing stays competitive at every volume level.
Receiving parts that don't match the drawing is a real cost — in time, money, and trust. We provide DFM feedback before machining, plus a CMM inspection report and first-article photos before any bulk shipment leaves our factory. NDA/NNN signed on request.
As a precision shaft couplings manufacturer, we handle all major coupling styles — built to your exact drawing.
Jaw / Spider Couplings
Bore 3–100mm, polyurethane or Hytrel spider, fail-safe design丨Applications: Motors, pumps, light conveyor drives
Disc / Diaphragm Couplings
Angular & axial misalignment compensation, no lubrication needed丨Applications: CNC spindles, servo automation
Bellows Couplings
High torsional stiffness, ±0.1mm axial travel, zero backlash丨Applications: Encoders, medical devices, robotics
Oldham Couplings
Parallel misalignment up to 0.5mm, low inertia丨Applications: Stepper motors, linear actuators
Rigid Shaft Couplings
Clamp or set-screw style, zero backlash, IT6 grade丨Applications: Servo systems, precision encoders
Flange Couplings
Custom PCD, bolt pattern to drawing, high torque capacity丨Applications: Heavy machinery, industrial drives
Sleeve / Muff Couplings
Simple one-piece design, keyway or interference fit丨Pumps, fans, low-speed shafts
Non-Standard / OEM
Fully custom from sketch, sample or CAD file丨Any industry, any spec
