Zero-Max Torq-Tender Overload Safety couplings protect critical rotating power transmission components from torque overloads. Torq-Tenders serve both as a safety device and as a coupling in a power transmission system. Torq-Tenders can be manufactured for systems requiring frequent washdowns such as food manufacturing and packaging applications. With the addition of an O-ring seal and simple […]

Torque Limiters that Keep Overload in Check for Heavy Equipment
A different approach is needed when designing mechanical torque limiters for high horsepower drives. The basic principles of mechanical torque limiter design are similar to those that have been known since some of the first machines were built, yet it remains a dynamic field. Function, space restrictions, safety considerations and continuously changing machinery design drive […]
Compact Precision Torque Limiters from R+W America
Based on a compact and simple design, the ESL series torque limiters from R+W offer accurate performance at a reasonable cost. Unlike traditional ball-detent torque limiters, the ESL spring loads two series of ball bearings against one another to create a rolling effect at overload. The rolling effect reduces wear and at the same time […]
Pneumatic Torque Limiter Provides Overload Protection
Nexen announced their TL Series pneumatically engaged, single-position torque limiters, delivering overload protection for industrial machinery. The TL Series uses a ball/detent interface and proximity sensor to immediately disengage the machine shaft when excessive torque or a machine jam occurs, effectively protecting downstream equipment and product from damage and decreasing downtime. Upon detecting the overload […]
Servo Torque Limiter from R+W America
Protection of an electromechanical system from torque overload is often assumed to be guaranteed by the current limits set in the drive parameters. But in the case of hard stops, impacts and other situations where overload occurs very rapidly, sufficient energy to do damage often exists in the rotating inertia driving the load. R+W servo-rated […]
Torque Limiters Tag-team to Prevent Overloads
For bottlers, protecting motion and assuring smooth, continuous operation in filler systems are critical in preventing system downtime. To guard against overloads and other system jam-ups, automated filling systems incorporate all types of devices including shear pins, electronic limit switches, and various types of mechanical stopping devices. These options may get the job done, but […]
