The disc coupling is made with two hubs and a thin metallic disc. The metallic disc is the torque-transmitting element. This type is designed to bend in different directions (parallel offset). The disc design is popular in servo, stepper and drive applications for taking the load off the bearings.
Two hubs & thin metallic disc
• Metallic disc transmits torque
• Two-disc style allows bends in different directions (parallel offset)
• Misalignment up to 5 degrees
• Torsionally rigid
|
|
No need for lubrication and maintenance.
There is no need to disassemble the coupling to inspect.
Additionally, the condition of the discs can be checked
while the machine is running, using a strobe light.
The machine misalignment can be assessed.
Torsionally rigid without any backlash.
No wearing parts, high resistance to harsh environmental
conditions.
Infinite life if properly aligned.

A jaw coupling is made with two metallic hubs with an elastomer (plastic) called the spider. The spider material is soft and mainly designed to absorb vibration. It is the first piece to wear and need to be replaced. The unit functions to minimize parallel or angular misalignment at high rpm. The spider center is ideal for motor connection applications needing shock absorption.
Two metallic hubs & a spider (elastomer)
• Conventional straight or curved jaw
• Ideal for servo applications
• Excellent shock absorption
• Curved jaws reduce deformation of spider
• Limits centrifugal force
• Balanced to handle high RPM, 40k+
• Functions with minimal parallel or angular misalignment
• Unit Transmits torque in event of spider failure
• Mix and match spider to accommodate multiple environments and applications
