Festo
556756
Swivel actuator unit DSL-40-125-270-P-A-S2-KF-B
The Festo 556756 is a double-acting industrial component featuring a rotary vane structural design with a 40 mm piston diameter, a 125 mm stroke, and an adjustable swivel angle range from 0 deg to 270 deg (reaching up to 272 deg with a -6 deg precision adjustment). This ball bearing-guided unit operates on compressed air per ISO 8573-1:2010 [7:4:4] at pressures between 2.5 bar and 8 bar, incorporating elastic cushioning rings at both ends, proximity switch position sensing, and a through piston rod variant. It delivers a maximum impact velocity of 500 mm/s, a maximum swivel frequency of 2 Hz at 6 bar, a swivel angle backlash of 0.05 deg, a repetition accuracy of 1 deg, and CRC 1 low corrosion stress resistance, while allowing oil lubrication.

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.
