Our tensioning devices are used extensively where slipping at specific torque tension is required to control the process. From controlling the arbor on material payout of paper rolls, plastic bag material, or yarns for weaving and braiding to controlling over-rotation in high speed bottling applications, these devices can be customized to meet the specific demands of your application.

Through precision machined components mated to provide smooth, accurate torque limit controlled slipping, these units can be used in any application, whether mounted directly to an arbor or as a direct coupling between two shafts to side drives with sprockets or pulleys - we have the solution to meet your needs. They are easily adjusted by hex nuts or threaded housing to vary the spring pressure. They range in torque capacity from ounce inches to 100 foot pounds and are available for input and output shaft or bore sizes from1/4" to 1-1/2" OD. |Protek-Sure Tensioning Device designed to couple a 1/2" input shaft to a 1/2" output shaft and provide a constant slip at a pre-set torque value.
