LINEAR ACTUATORS | Rolaram
Example
Dynamic Load = 50 kN (in compression)
Linear Speed = 900 mm/minute Stroke = 1500 mm
Parallel drive configuration, unguided ram, fitted with a clevis end, trunnion mounting (without feet) and proximity switches.
Step 1
Using load/speed curves on page 8, select model R125.
Step 2
Referring to Technical Chart for Model R125-Parallel Configuration on page 11, select product code R1251040.
Step 3
The required stroke of 1500 mm is less than the maximum shown (1600 mm).
Step 4
The complete product code is therefore R1251040-P-P-1500-C-TN-P-0
5. How to Select a Rolaram® Actuator
There are 4 simple steps as follows :
Step 1
Using the load/speed curves on page 8, select the actuator model
which has an adequate dynamic load capacity for the required
linear speed. Positional accuracy and life considerations may
dictate selection of the roller screw version for models R075, R100
and R125.
Step 2
Referring to the Technical Charts (page 11) for that model, select
the nearest linear speed for the chosen right angle or parallel drive
configuration.
Step 3
Check the required stroke is within the maximum stroke limit.
Step 4
Choose the end fitting, mounting arrangement and other options
required to complete the full product code shown on page 7.
