Festo
556429
Swivel actuator unit DSL-20-25-270-P-A-S20-B
This Festo industrial component, part number 556429, is a double-acting rotary vane actuator featuring a 20 mm piston diameter, a 25 mm stroke, and a swivel angle adjustment range of 0 degrees to 270 degrees (total angle 0 degrees to 272 degrees) with a -6 degree precision adjustment. Designed with a through, hollow piston rod, a plain bearing-guide for torsion protection, elastic cushioning rings at both ends, and position sensing via proximity switch, the unit operates on compressed air meeting ISO 8573-1:2010 [7:4:4] standards at pressures from 2.5 bar to 8 bar. It achieves a maximum swivel frequency of 2 Hz at 6 bar, a max impact velocity of 500 mm/s, a 2 degree swivel angle backlash, a 1 degree repetition accuracy, and a CRC of 1, while accommodating 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.
