The S200MYM032025 is a precision gear and dial hub made of 303 stainless steel with a 3.2 mm bore and a 13 mm outer diameter, designed to mount gears or dials without keys or splines. It features a 0.75 mm diameter pin, two 0.25 mm x 45° chamfers, and a socket head set screw rated for M2 threading. The bore tolerance is +0.019 mm, and concentricity is held to 0.008 mm. The part uses an r6 shaft fit and requires an H7 tolerance on the mating bore for a press fit.
SDP/SI's precision gear and dial hubs are made to accommodate gears or dials and eliminate keys and splines. They are made of 303 stainless steel and are also available with our exclusive Fairloc® design, which is perfect when the hub O.D. is limited; it can be tightened and released repeatedly without marring the shaft or affecting torque-transmitting abilities.
