Overview
This drive features a highly rigid output shaft with a flange mounting surface for directly mounting tables, gears, and sprockets. This type features a “user-friendy” design that allows you to place a large bore through-hole in the center of the output shaft and then attach a fixed shaft to the center of the output shaft, or attach peripheral equipment for indexing drives.
Features
Flange Output
Dials, gears, sprockets, and other elements can be mounted directly to the output shaft.
Wide Product Lineup
Available in many sizes and indexing configurations.
High Speed
High speed input (700 rpm for models 4.5DF to 25DF)
High Rigidity
Flange output surface stays rigid in all directions.
Flexible Mounting Positions
Index mounts in any position with gearmotor mounting on either side of the index.
Typical Applications
  • Food packaging machines
  • Electronic component assembly machines
  • Conveyors and inspection machines for rubber products
  • Drive for linear motions in automatic machinery
