NEWS - Sizes 19 to 48 are now in stock, bored and keyed and ready to be delivered

These are low cost, no fuss shaft couplings. The JAW shaft couplings are available in steel, cast iron and aluminium and can come with ATEX approval if requested. To suit shaft sizes from 6mm to 100mm or supplied pilot bored.

The curved jaw coupling design consists of an elastic “spider” and two hubs. The spider, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. These spiders allow the user to customize the jaw coupling’s performance. Selecting a soft spider will give the jaw coupling the greatest dampening characteristics, while a hard spider will provide the greatest torque capacity and strength. The jaw coupling can also be considered as a fail safe device. If the spider fails, the jaws of the two hubs interlock allowing direct power transmission, allowing the application to be safely shut down for maintenance.

The spider types (by size) are then matched to the following hub sizes. Each hub size is available in a range of pre-bored sizes. To make a complete shaft coupling you will require two hubs and one spider.

There are three standard spider materials offering different torque capabilities to choose from. All spiders have an open centres to allow minimum DBSE.

92 Sh-A Purple Spider - (10Nm to 6650Nm) Suitable for use with all hub materials, offering high dampening properties. Ideal for use in general engineering.(Spider can also be yellow in colour)

98 Sh-A Red Spider - (17Nm to 10000Nm) Suitable for use with cast iron and steel hubs, offering medium torque capacity and dampening properties.

64 Sh-G Green Spider - (21Nm to 12500Nm) Suitable for use with cast iron and steel hubs, offering high torque capacity and minimal dampening properties.

L Jaw shaft coupling

The TBWoods L Jaw couplings are designed to meet high-quality standards whilst remaining affordable. The L-Jaw type Elastomeric coupling  is available with four insert / spider materials, Burna-N, Urethane, Hytrel and bronze as standard making it adaptable for variable-speed and variable- torque applications .

Key features for L-Jaw

  • To suit shaft diameters 3mm to 70mm
  • 100% interchangeable with industry-standard designs.
  • L-Jaw   offer reliable solutions for uniform to heavy loads
  • L-Jaw uses easily replaceable individual cushions for maximum reliability with heavy torque loads
  • Built for durability, designed for extreme conditions
  • Ideal for use with variable-speed and variable- torque applications
  • No lubrication
  • No maintenance.

Ideal solutions for applications ranging from standard-duty electric motors to steam turbines and high-torque motors. The Jaw couplings are available in a wide range of sizes using BTS (bored to suit) hubs.

Ideal solutions for applications ranging from standard-duty electric motors to steam turbines and high-torque motors.
