Curved jaw couplings

The extensive range of curved jaw shaft couplings provides simple and economic solutions for shafts up to 90mm.

Curved jaw couplings dampen oscillations and vibrations and can compensate for shocks in the drive train.

Type GR

The base program - simple and economic solutions for shafts 10 to 90mm, torque up to 165Nm.

• Cast iron or aluminium hubs with polyurethane elements
• Temperature range -30 to +80oC
• 2 grades of element, 92 shore (white) and stiffer 98 (red)
• Angular misalignment 1.5o, twist at rated torque 2.5°. Allow a safety factor of 3.5 with torque reversals

Type GESM

Precision clamp hub curved jaw couplings. Flexible couplings with higher precision resulting in backlash free connections.  Clamp hub design removes the need for keyways.  Shafts 5 to 45mm, torques up to 187Nm.

• Zero backlash
• Variable torsional stiffness
• Extremely fast assembly
• Shaft tolerance h7
• Hubs fully machined to give precision fit with element
• Torque capacity depends on shaft size and model chosen

Type GESA

High torque clamp hub curved jaw couplings - high torque backlash free couplings using shrink discs for connection to the shafts without keyways. Shafts 10 to 42mm, torques up to 450Nm.

• Zero backlash
• Variable torsional stiffness
• High torque capacity
• Shaft tolerance h7
• Hubs fully machined to give precision fit with element
• Torque capacity depends on shaft size and model chosen
