Rexnord SRM100047A Sun Gear

Rexnord SRM100047A Sun Gear is a sun-gear component for Rexnord Planetgear speed reducers, part of the PGSTK family that serves as the input element in a planetary gear train. It carries a sun-gear designation of 3.32 and a catalog/reference number 10494712, aligning with Rexnord’s line of sun gears used in SRM-series planetary gear sets. In a planetary assembly, the sun gear engages the planet gears carried by the planet carrier and works with the ring gear to achieve gear reduction and torque transmission; this SRM100047A is designed to mate with compatible Rexnord planet gears, carriers, and housings within the PGSTK lineup. Manufactured by Rexnord, this sun gear provides a precise fit for SRM-series sub-assemblies and Rexnord planetary gear systems that specify the SRM sun-gear interface, ensuring proper alignment and performance in industrial gear-reduction applications.
