Torque Limiters

Brunel Torque Limiters eliminate the problems associated with slow reaction electrical overload devices, shear pins which give a wide release torque variation, or slip clutches which may rapidly overheat.

Brunel products can save you money – the initial cost is frequently more than covered by the saving in down-time even on the first overload.

Bores and Keyways
Standard bores and keyways are manufactured to H8 and Js9 tolerances to BS4500: 1969, both in Metric and Imperial dimensions.
During assembly all units are packed with a 3% Molybdenum Disulphide (MoS2) grease BP Energrease L21 M. Because of their unique fully enclosed design all units need only be stripped and re-packed with grease every two years. However, under extremely adverse conditions of environment and duty please consult Brunel Corporation.
Running in Oil
All Brunel units can be run in oil if required without affecting performance.
