Curtis SS647BKW1SS Outer Diameter: 1 1/8" stainless steel single joint w/ hubs bored 1/2 of O.D. keyways and installed

Many applications require corrosion resistant universal joints to assure sanitation or to avoid premature oxidation or deterioration. Curtis’ 303 grade stainless steel u-joints are particularly important, for example, to industries that use food processing equipment, and for machinery that comes in contact with corrosive chemicals or is exposed to water for long periods. Furnace applications also benefit from stainless steel, which better withstands high temperatures and other environmental extremes. Curtis stocks 303 stainless in all 14 sizes from ³⁄₈” to 4″. Stainless steel grades 304, 316 and others available by special order. Standard turn-key joints have standard bores, keyways (⁵⁄₈” joints and larger) and set screws already installed.
