Festo
540859
Three-point gripper HGDT-25-A
The Festo 540859 is a double-acting industrial component featuring a 3-point gripper function with three gripper jaws driven by an inclined plane structural design and positively driven motion sequence. This pneumatic gripper operates at pressures from 3 bar to 8 bar with sealing air pressure up to 0.5 bar, delivering a repetition accuracy of 0.03 mm, a max operating frequency of 4 Hz, and gripping forces up to 246 N opening and 207 N closing at 6 bar. Position sensing is accomplished via a proximity switch while accommodating any mounting position with a size 25 format, 3 mm stroke per gripper jaw, 0.2 mm max interchangeability, 0.1 deg max angular play, and 0.05 mm max backlash.

Request a QuoteWhy no listed price?
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.
