Zero-Max’s Torq-Tender overload safety devices incorporate torque limiters for dependable overload protection. When a jam-up or excessive loading occurs, the built-in torque limiter provides quick and reliable release capabilities, preventing system damage.

Mechanical Torque Limiter Advantages
The Torq-Tender overload safety device is tamper-proof. Once installed, the torque "trip" torque value cannot be changed. This feature ensures the integrity of the machined design and renders costly and potentially risky calibration procedures unnecessary. Torque value is controlled by the part number ordered; that value determines what spring set is used during the assembly of the torque limiter.

Torque values can be changed in the field. However, the torque limiter must be disassembled and replaced with different springs to achieve the new torque value.
Standard Torq-Tenders are bi-directional. Torque value remains the same regardless of rotation. If specified, the torque limiter can be configured at the factory to release at different torque values for different rotational directions.
When used as a coupling, the Torq-Tender fulfills two functions: 1) A flexible shaft coupling; and 2) a mechanical torque limiter.
In the shaft-to-shaft configuration, the Torq-Tender can accommodate angular shaft misalignment up to 1.5° and parallel misalignments from 0.005” to 0.015”.
The enclosed design of the mechanical torque limiter enables it to operate in a wide variety of industrial environments. Custom designs and materials can meet unique requirements and withstand even the most adverse conditions.
