Nexen 951281, Air Engaged Torque Limiter

Nexen 951281 Air Engaged Torque Limiter - 40 mm bore, NSB metric design, single-unit pack for automated lines and conveyors.
✔️ 40 mm bore air-engaged torque limiter, 500 Nm max torque, 102 Nm min torque

The Nexen 951281 is an air-engaged torque limiter designed for precision drives in automation, packaging lines, conveyors, and machine tools. This compact clutch system uses compressed air to engage a torque-limiting element, providing reliable overload protection and smoother shutdowns on startup. The TL40A 40 mm bore model sits in a 12-model family with torque capabilities up to 1350 Nm and speeds up to 2000 rpm, making it a flexible choice for a range of offset-shaft applications. Proximity sensing with a 0.91 m cord and included hardware simplifies integration, while tapped mounting holes and the ability to attach pulleys, sprockets, or gears for offset shafts add mounting versatility.
