Brand: Festo

Swivel actuator unit DSL-25-50-270-CC-A-S20-KF-B

The Festo part number 556670 is a double-acting industrial component featuring a rotary vane structural design with a 25 mm piston diameter, a 50 mm stroke, and a ball bearing-guided mechanism providing torsion protection. This unit operates at a pressure range of 2.5 bar to 8 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4], with oil lubrication permitted and required for continued operation. It delivers an adjustable swivel angle from 0 deg to 246 deg, a -3 deg precision adjustment, a 10 deg cushioning angle, a 0.05 deg swivel angle backlash, and a 0.1 deg repetition accuracy, utilizing pneumatic shock absorbers and elastic cushioning rings at both ends. Position sensing is accomplished via a proximity switch, supporting a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 1 Hz at 6 bar, and incorporating a through, hollow piston rod in any mounting position.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
