{"title":"Machine Friction Disc Lock Washer Torque Limiter Coupling","handle":"machine-friction-disc-lock-washer-torque-limiter-coupling","url":"/products/machine-friction-disc-lock-washer-torque-limiter-coupling","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.\n\nThe 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.\n\nKey Features\n\n\nOverload Protection – Slips at preset torque to protect downstream components\n\nAuto Re-Engagement – Resumes normal operation once the overload is removed\n\nAdjustable Torque – Spring force tuned via nut or bolt to set sliding torque (34–149 N·m)\n\nDurable Construction – 45-grade steel body with non-asbestos friction plates\n\n\nSpecifications\n\n\nModel – TL350-2 (with keyway and bore)\n\nInner Bore Diameter – 22.23 mm\n\nKeyway Width – 4.78 mm\n\nTorque Range – 34–149 N·m\n\nMaximum Speed – 5,600 RPM\n\nWeight – 2.48 kg\n\nBody Material – 45-grade steel\n\nFriction Plate – Non-asbestos material\n\n\nIdeal For\n\nProtecting drive trains and conveyor systems from overload\nRobotics and automation applications\nMachine tool and industrial equipment safety\n\n\nPackage Contents\n\n1× TL350-2 Torque Limiter Coupling\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5470,"title":"Default Title","sku":"DF-FIT0589","price":282.9,"on_sale":false,"in_stock":true,"available_quantity":3,"option1":"Default Title"}]}
