The Jaw style shaft couplings from Abssac are a low cost, no fuss flexible shaft connection...The curved jaw coupling design consists of an elastic ‘spider’ and two hubs. The spider utilises advanced polyurethane materials to provide reliable torque transmission as well dampening of impulse loads. With a selection of spider to choose from allows the user to customise the jaw coupling’s performance.
Selecting a soft spider material will give the jaw coupling the greatest dampening characteristics, whilst a hard spider will provide the greatest torque capacity. Hubs are available in cast Iron or Aluminium and all hub sizes are stocked with bore and keyways to suit shaft sizes from 6mm to 60mm (or pilot bored). The Jaw couplings are rated from 10Nm up to 665Nm and are a direct replacement to other industrial jaw couplings. If you are a user of the Jaw style shaft coupling then give us a call to get a competitive quote. We hold large stocks of the following sizes.
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.
