Festo
556496
Swivel actuator unit DSL-25- -270-CC-A-S20-B
This Festo rotary vane industrial component features a 25 mm piston diameter, a 10 mm to 160 mm stroke, and a double-acting mode of operation with an operating pressure range of 2.5 bar to 8 bar. The unit provides a swivel angle of 0 deg to 246 deg with a 10 deg cushioning angle, 2 deg swivel angle backlash, 0.1 deg repetition accuracy, and -3 deg precision adjustment, incorporating both pneumatic shock absorbers and elastic cushioning rings at both ends. It operates with compressed air as per ISO 8573-1:2010 [7:4:4], supports oil lubrication, and includes a plain bearing-guide, through hollow piston rod, and proximity switch position sensing for any mounting position at a maximum impact velocity of 500 mm/s and a maximum swivel frequency of 1 Hz at 6 bar.

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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
