Festo
11651
Standard cylinder ESN-8- -P
The Festo part number 11651 is a single-acting industrial component featuring a pushing action mode of operation, an 8 mm piston diameter, and a stroke range of 1 to 50 mm with an M4 male piston rod thread. Conforming to CETOP RP 52 P and ISO 6432 standards, this single-ended piston rod design incorporates flexible cushioning rings at both ends, operates within a working pressure of 1.5 to 10 bar, and delivers a theoretical force of 24 N at 6 bar during the advance stroke. Designed with any assembly position and a CRC 2 moderate corrosion resistance classification, it utilizes compressed air according to ISO 8573-1:2010 [7:4:4] and supports lubricated operation.

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.
