Dependable and corrosion resistant, Adjustable Torque Limiters work on a spring-loaded convex pin and detent design that disengages the motor drive when a jam up or excess overload occurs. Once overload is removed and speed reduced, precision tempered Carbon Steel torque springs automatically expand with a resetting action that engages the drive shaft and puts the entire drive system back into motion at its original angular position. Adjustable Torque Limiters continue to operate and protect, even after repeated overloads. When operating conditions require periodic changes, torque settings can be adjusted via external compression bolts. These units react to overloads - not to lubricants - so unlike friction-type torque limiters they can be submerged in oil and still provide precise disengagement at your design limits. Constructed with long-wearing Delrin pins inside a durable Nylatron GS housing, Adjustable Torque Limiters resist water, salts, mild acids and many other corrosive elements and abuse, even in temperature ranges from -40 to 180 F (-40 to 82 C). Since disengagement does not generate heat that might alter disengagement characteristics or wear out faces of the unit, you get the same accurate overload protection time after time. Units are fitted with Plated Steel 1/4-20 hex head bolts for external adjustment of spring tension on the Delrin pins. In hard to reach applications, use set screws for spring tension adjustments. In corrosive environments, bolts or set screws made of Nylon may be substituted. Bore tolerance: +0.002/ -0.000 inches.
