POWER TRANSMISSION COUPLINGS!

jbj Techniques Limited, quality products for mechanical and fluid power

the right coupling for power transmission
jbj Techniques provide probably the widest range of couplings for power transmission available within the UK with 14 different designs and 22 different styles in our gear couplings alone.

Ranging from miniature couplings, all steel gear couplings, flexible spider couplings, shaft couplings, torque limiting couplings, disc and grid type couplings, ATEX compliant and shaft locking devices.

There are a range of criteria (link to selection table) in specifying the most suitable coupling for your application but we will guide you all the way to obtain the right coupling for power transmission.
