ZLW Dual X Connecting Shaft
1. When the 2 linear actuators are mounted, measure the distance between shaft ends (D)
2. The length of the connecting shaft (L) may need to be cut to accommodate the proper spacing for the Drive
Couplings. Use the following formula to calculate L.
i. (metric) L = D – 38 mm
ii. (imperial) L = D- 1.5”
NOTE: This formula is for AutomationDirect Drive Coupling SRBA-39C-10-10 only.
3. Cut Connecting Shaft, A-AWM-10-xxx to the proper length (L). If the Connecting Shaft is greater than 500mm,
use Pillow Block Support A-KSTM-10 midway along Connecting Shaft to minimize shaft whipping during high
speeds.
4. Slide 2 Drive couplings, and optional Pillow Block Supprt, onto the Connecting Shaft. Align this subassembly
with linear actuator drive shafts.
5. Slide the couplings onto the 2 drive shafts and tighten coupling clamp screws.
6. If the Connecting Shaft is out of alignment, adjust the mounting of the Linear Actuators to correct.
7. Slide the Connecting Shaft into position of 1 Drive Coupling and tighten clamp screw onto the drive shafts.
8. Move Carriages of both actuators to same end of stroke and tighten 2nd Drive Coupling clamp screw to
Connecting Shaft.
