Festo
8103491
Twin cylinder DGTZ-GF-20-50-J-T-P-A
The Festo 8103491 is a double-acting industrial guide drive unit featuring a 20 mm piston diameter, a 50 mm stroke, and a plain-bearing guide operating with two yokes. It utilizes elastic cushioning rings at both ends with an adjustable end position range of 10 mm, delivering a theoretical retracting force of 283 N at 6 bar across an operating pressure range of 1.2 bar to 8 bar. Designed with ISO Class 5 cleanroom suitability, VDMA24364 Zone III LABS conformity, and CRC 1 corrosion resistance, this component supports compressed air media per ISO 8573-1:2010 [7:4:4] with optional oil lubrication. Position sensing is achieved via proximity switch, operating within an ambient temperature range of -10 °C to 80 °C in any mounting position.

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.
