The Alpha Series is an all-in-one indexing drive package complete with a cost-effective shaft-mounted gearmotor on a low-profile housing. After reviewing the design, this indexing drive has been made more user-friendly by building on the roller gear cam mechanism found in all of our SANDEX products, which have set high production records.
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 Rigidity
Flange output surface stays rigid in all directions.
Compact
Thin profile housing
Standard Equipped Gearmotor
The Alpha Series come with a variable frequency drive gearmotor with a hollow output shaft.
- Welding machines for automotive parts
- Tire assembly machines
- Manufacturing equipment for solar panels
- Various assembly and inspection machines
