BCS RODLESS SCREW DRIVE ACTUATORS Endurance Technology features are designed for maximum durability to provide extended service life. This rodless style actuator is designed for carrying light to moderate loads at an economical price. Based upon our BC2 pneumatic band cylinder, it utilizes a guidance system consisting of an adjustable carrier bracket with two solid bearing rods that transmit the load to the actuator body for superior load support. Built-to-order in stroke lengths up to 3 m [120 inches] with multiple screw options available. ADJUSTABLE CARRIER BRACKET • Allows for easy...

DYNAMIC BENDING MOMENTS AND LOADS Please see BCS Carrier Bracket Bolt Adjustment on page BCS_6 Breakaway torque will increase when using the Auxiliary carrier option. When ordering, determine your working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated. *Loads shown in table are at minimum “D” dimension, for ratings with longer “D” dimension see graph below. Rates shown on charts were calculated with these assumptions: 1.) Coupling between carriers is rigid. 2.) Load is equally distributed between carriers.
