Keystock is used to provide driving torque between two moving parts. They are often used in conjunction with a coupling to allow for higher torque capabilities in the application and prevent slippage on the shaft. Ruland square keystock is supplied in 12” (300mm) lengths allowing the user to cut it down to the appropriate size for their application. They have a plus tolerance to assure tight fit with the keyway for positive, zero backlash power transmission. Ruland keystock is straight type with square pre-cut keys. They are available in zinc plated steel for higher torque applications as well as stainless steel for corrosive environments. Ruland square keystock is US manufactured and RoHS compliant.
