Standalone planetary reducers feature a floating sun gear and a ring gear around three planetary gears.

Features & benefits

  • Unlike planetary gears that are fixed in place, the sun gear has a toothed central spline loosely fitted onto the shaft spline, creating a floating sun gear

  • Primary advantage of floating sun gear is quieter operation; when clamped to the motor shaft, the sun gear rattles if tolerances vary at all, indicating that gearbox is out of tolerance

  • Standard configuration allows mounting to any motor with a NEMA 23 or 34 input flange

  • Standard design contains powdered metal gears; optional rugged design with steel gears withstands harsh conditions
