AR-COL

AR-COL Rotary actuators with plate, collector and 4 ways air shaft

FEATURES:

The rotary actuators series “COL” derive from FAM 2.3 with admixture 4 – ways, integrated into the principal spindle, to feed the supplementy objects in rotating position.
In this model of rotary actuators the “collector”, where the tubes are connected with supplementary feeding, is joined to the principal spindle and it turns with it.

Spindle rotation, supported on prestressed oblique bearings, is assured by a pair of rack pistons in treated steel.
Rotation angle can be adjusted with precision, with a total extra stroke approx. of 2°, through two threaded pushroads and one or two contrast blocks built into the cap (optional).
The stop is made directly on the spindle assuring precision and reliability.

Deceleration is guaranteed by hydraulic shock absorbers, with incorporated cartridge and pressure-tight, with act on the rack piston and the rotation can be controlled via integrated sensors, that detect the magnetic field generated by a rubber magnet ring fixed up one of two rack pistons. It is possible to have as optional the rotation control with proximity sensors fixed with two external grub screws (to stop the actuator) to detect the spindle position.

In questi modelli di attuatori è possibile avere come opzionale il controllo della rotazione con sensori di prossimità induttivi montati con i puntali filettati esterni di arresto dell’attuatore, e rilevare quindi direttamente la posizione dell’albero.

All versions have an internal circuit that feeds both sides of the piston (to obtain the maximum torque) connected only on side pneumatically for simplicity and to save space.

The actuators have a predisposition to work eighter with air or with oil, with the pressure indicated into “specifications”.

The actuator body is an hard-anodised aluminium alloy; the rotating spindle, the gear and the rack pistons are in UNI 39 NiCrMo3 nitriding-hardened steel.
