DIA51, DIA201 - ACME 1" diameter, .25" pitch, .50" lead
DIA51, DIA201 - ACME 1" diameter, .25" pitch, .50" lead
Joyce integrated actuators with double lead Acme screws (DIA) lift one ton. Requiring only electric power, Joyce integrated linear actuators may be used in place of hydraulic cylinders, eliminating the cost and potential for leaks associated with hydraulic systems. Translating tube (TT) integrated linear actuators are well suited for use in industrial environments where protection of the lifting screw mechanism and low maintenance is desired. Traveling nut (TN) integrated actuators are best suited for use in environments that are relatively clean and free of dust.
- Double lead, 1” diameter, .25” pitch, .50" lead screw
- Durable aluminum housing with integral NEMA 56C-face motor flange
- Optional motor size based on load capacity
- Optional limit switch and accessories
- Brake motor recommended to hold position
- Capable of speeds from 28 to 172 inches per minute
- For travel lengths greater than 24" contact [email protected]

Lead: The distance traveled axially in one rotation of the lifting screw.
Pitch: The distance from a point on a screw thread to a corresponding point on the next thread, measured axially.
Important Note: DIA models may lower under load. Brake motors or external locking systems are recommended.
