Pneumatic torque limiter TL series

Nexen’s pneumatically engaged, single-position torque limiters are the highest quality and most efficient overload protection devices for industrial machinery on the market today. Pneumatic Torque Limiters protect equipment by immediately disengaging the machine shaft when excessive torque or a machine jam occurs. Each unit comes with a Turck® Proximity Sensor to detect torque overloads. The Advantage of Air Pneumatic actuation allows remote torque adjustment while the machine is running, eliminating continuous trips to make adjustments. Mounting Options Nexen's bearing-supported pilot Pneumatic Torque Limiters accept numerous mounting configurations, including sprockets, timing belt pulleys, and HTD sprockets. Nexen's single-flex or double-flex couplings match the drive flange pilot surface and bolt circles. These couplings provide high shaft misalignment protection, zero backlash, and excellent torsional rigidity. These couplings connect companion shafts inline and provide misalignment protection for the Torque Limiter drive flange bearings. Turck Proximity Sensors The mounting configuration of the Turck Sensor allows full gear reducer shaft insertion into the bore for inline shaft coupling installations, ensuring proper torque transmission and easy mounting. The 24VDC proximity switch is easy to set up and works with PLC controls. Smart Controllers Smart Valve Controllers are available that accept feedback from the engagement sensor to control air to one or multiple torque limiters. Controllers are available with optional higher, timed-out start-up torque settings.
