Coupling

Coupling

Our industrial couplings deliver smooth, reliable torque transmission while accommodating necessary shaft misalignment. They are essential components for protecting drivetrains and reducing mechanical shock.

Coupling

Jaw Coupling

Curved-jaw couplings with a polyurethane star spider, from compact L-type to heavy XL/GR clamp hubs. Interchangeable with the common GR, L, HRC and pump-coupling sizes.

Nominal torque

4.5 – 12,000 N·m

Bore range

5 – 130 mm

Coupling

Plum Blossom Coupling

Claw couplings that transmit torque through a multi-lobe polyurethane element: ML (GB/T 5272 LM) plum blossom couplings, NM multi-cam couplings and FALK-R housed couplings.

Nominal torque

20 – 15,000 N·m

Bore range

7 – 190 mm

Coupling

H-Block Elastic Coupling

Flexible couplings that drive through separate H-shaped elastic blocks. Blocks change without moving the hubs; spacer and brake-disc versions are available.

Nominal torque

19 – 19,000 N·m

Bore range

Up to 190 mm

Coupling

Gear Coupling

Crowned-tooth gear couplings, from maintenance-free nylon-sleeve NL and TGL types to all-steel TGCL and GIICL drum gear couplings for heavy torque.

Nominal torque

10 – 174,000 N·m

Bore range

6 – 265 mm

Coupling

Pin & Bush Coupling

Flanged couplings that drive through nylon pins or rubber-bushed pins: simple, rugged and repairable on site, for medium to very high torque.

Nominal torque

6.3 – 180,000 N·m

Bore range

9 – 340 mm

Coupling

Tyre & Elastic Sleeve Coupling

Highly flexible couplings with a rubber tyre, split urethane element or toothed elastomer sleeve. They take large misalignment and soak up shock and torsional vibration.

Nominal torque

10 – 38,400 N·m

Bore range

8 – 229 mm

Coupling

Disc Coupling

All-steel diaphragm couplings with stacked stainless disc packs: zero backlash, torsionally stiff and maintenance-free, rated to 280 °C.

Nominal torque

9.8 – 173,830 N·m

Bore range

3 – 290 mm

Coupling

Chain & Grid Coupling

Roller chain couplings for simple, tolerant low-speed drives and serpentine spring grid couplings for heavy torque with shock damping.

Torque range

40 – 932,000 N·m

Bore range

13 – 600 mm

Coupling

Servo & Precision Coupling

Small, low-inertia aluminium couplings with clamp hubs for servo and stepper motors, encoders and ball screws. Zero-backlash disc, bellows and slit designs.

Torque range

0.8 – 520 N·m

Bore range

3 – 68 mm

Coupling

Rigid Coupling & Torque Limiter

JK clamp-shell rigid couplings, friction and ball-detent torque limiters that protect drives from overload, and the bell housings and brackets that mount pumps to motors.

Rigid coupling torque

25 – 15,000 N·m (JK)

Torque limiter setting

2.9 – 1,860 N·m (TLC), 5 – 1,200 N·m (JTAL)
