Electric Cylinders

Electric Cylinders Electric Cylinder Operation: The input shaft (worm) shaft rotates a wormgear, which in turn rotates the lifting screw. As the lifting screw rotates, it forces the lifting nut (fixed to the cylinder tube) to translate, thus extending or retracting the cylinder tube. For proper operation, the load being lifted must be restrained from rotation. Joyce/Dayton offers Electric Cylinders in several models including: • Standard • Motor mount • ComDRIVE® A guide for ordering is on pages 120 and 121. 2D and 3D models available on website • Ordering information on pages 120 and 121

Electric cylinders ORDERING INFORMATION Instructions: Select a model number from this chart. 2.5-Ton Acme Screw ECAL242.5 ECAH62.5 ECAH122.5 ECAH242.5 Important Note: Electric Cylinders that are ≥ 30% efficient may lower under load. Brake motors or external locking systems are required. Detailed information about each electric cylinder model is available on pages 125-134.

Electric cylinders MODELS Standard The Joyce standard electric cylinder is intended for applications where the customer provides their own drive mechanism. To determine capacity, input torque, and turns-per-inch use the specification chart on page 123. This design can also be used where one or more electric cylinders are being driven by one common drive motor or in combination with the motor mount (direct drive) or ComDRIVE® models listed below. Example part number: ECAL635C-15.00-STDX-HW08-X Acme screw (ECA), low lead (L), 6:1 gear ratio (6), 3-ton capacity (3), female clevis (5), clevis...
