## Description

A spring-loaded friction torque limiter (model TL350-2) that protects drive systems from damage caused by shock loads, overloads, or machine jams. When torque exceeds the preset threshold, the coupling slips to absorb the overload, then automatically re-engages when the condition clears. The sliding torque is adjustable by turning the spring-loaded nut or bolt. The unit can be used as a centre member with a sprocket, gear sheave, or flange plate sandwiched between the friction surfaces. Key Features Overload Protection – Slips at preset torque to protect downstream components Auto Re-Engagement – Resumes normal operation once the overload is removed Adjustable Torque – Spring force tuned via nut or bolt to set sliding torque (34–149 N·m) Durable Construction – 45-grade steel body with non-asbestos friction plates Specifications Model – TL350-2 (with keyway and bore) Inner Bore Diameter – 22.23 mm Keyway Width – 4.78 mm Torque Range – 34–149 N·m Maximum Speed – 5,600 RPM Weight – 2.48 kg Body Material – 45-grade steel Friction Plate – Non-asbestos material Ideal For Protecting drive trains and conveyor systems from overload Robotics and automation applications Machine tool and industrial equipment safety Package Contents 1× TL350-2 Torque Limiter Coupling
