Product BrochureProduct Details:

A rubber spider coupling is a type of flexible shaft coupling commonly used to transmit torque between two shafts while compensating for slight misalignments, vibration, and shock. It consists of three main parts:

1. Two metal hubs – Each is mounted on a shaft.

2. An elastomeric element (the "spider") – Made of rubber or similar material, it fits between the hubs.

Key Features:

• Vibration dampening: The rubber spider absorbs shock and vibration.

• Misalignment compensation: Handles angular, parallel, and axial misalignment to a limited extent.

• Easy maintenance: The rubber spider is replaceable.

• No lubrication: Dry operation makes it clean and low maintenance.

Common Types:

• Jaw Couplings: The most popular design using a rubber spider. The spider fits between curved jaws of two hubs.

• Oldham and gear couplings may also use elastomeric elements but are different in structure.

Applications:

• Pumps

• Compressors

• Conveyors

• Gearboxes

• Small to medium-sized motors

Rubber Materials:

• NBR (Nitrile rubber) – General-purpose

• Polyurethane – Higher torque and temperature resistance

• EPDM or Silicone – For specialized chemical or thermal conditions
