Festo
556492
Swivel actuator unit DSL-25- -270-P-A-S2-B
The Festo part number 556492 is a double-acting rotary vane industrial component featuring a 25 mm piston diameter, a stroke range of 10 mm to 160 mm, and an adjustment range of swivel angle from 0 deg to 270 deg with a maximum swivel angle of 272 deg. This unit operates on compressed air as per ISO 8573-1:2010 [7:4:4] within an operating pressure of 2.5 bar to 8 bar, utilizing elastic cushioning rings or pads at both ends, a plain bearing-guide for torsion protection, and a through piston rod variant. It achieves a repetition accuracy of 1 deg, a swivel angle backlash of 2 deg, a precision adjustment of -6 deg, a maximum impact velocity of 500 mm/s, and a maximum swivel frequency of 2 Hz at 6 bar with any mounting position and a corrosion resistance class of CRC 1. Position sensing is accomplished via a proximity switch, and oil lubrication is possible and required for further use under low corrosion stress conditions.

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.
