Transmission protection from mechanical overload by using the range of Torque Limiting Couplings; Sliding Hubs and Safety Clutches available from jbj Techniques Limited.

» Torque limiting up to 23,000 Nm.

» Coupling prevents high shock loads.

» Standard brass bushes for extended durability.

» Torque adjustment possible even in assembled condition.

» Acid resistant versions available on request.

» Units finish machined to suit customer applications.

These torque limiters are designed for machines with chain, gear or belt drives to prevent overloading of sensitive motors, gearboxes and machine components.

If overloading causes the level of transmitted torque to exceed the frictional torque between the two friction discs, which is created by the pretensioned disc spring, the coupling slips and forcibly breaks the connection between the driving and driven side. When the torque subsequently falls to a level below that of the frictional force, the friction discs re-engage and torque transmission without backlash resumes.

20 different high-quality versions that can be adapted to the varying conditions of almost all drive systems are available.

Adjustable torque from 0.5 to 23.000 Nm.

Stepless adjustable torque.

Long life due to very little wear.

Surface protected by galvanizing and yellow cromatizing.

High quality torque limiting couplings, fully-machined components with a special rustproof surface coating. This series of torque limiters are completely enclosed to prevent dirt from contaminating the interior. They allow stepless adjustment of the required slip torque, even when already installed.

These torque limiters have been constructed to allow easy adaptation to a wide variety of operating conditions, not only for frequent slippage at low torque, or low friction and extremely high torque, but also for all intermediate levels of torque, friction and desired service life length.
