Machine Friction Disc Lock Washer Torque Limiter Coupling

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
