Festo
556618
Swivel actuator unit DSL-20-25-270-P-A-S2-KF-B
This Festo industrial component, part number 556618, features a rotary vane structural design with a 20 mm piston diameter, a 25 mm stroke, and a double-acting mode of operation. Engineered with ball bearing-guided protection against torsion, it delivers a swivel angle of 0 deg to 272 deg with an adjustment range of 0 deg to 270 deg, a precision adjustment of -6 deg, and a swivel angle backlash of 0.05 deg. The unit operates on compressed air as per ISO 8573-1:2010 [7:4:4] within an operating pressure range of 2.5 bar to 8 bar, utilizing elastic cushioning rings or pads at both ends, position sensing via proximity switch, and a through piston rod variant.

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.
