Festo
177258
Swivel/linear unit DSL-40-25-270-P-S20-CC-KF
The Festo 177258 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 25 mm stroke, and a 240-deg swivel angle with a 270-deg rotation angle adjustment range. Operating at 2.5 to 8 bar with dried compressed air, this unit delivers 20 Nm of torque at 6 bar and includes dual-end shock absorber and flexible cushioning along with a ball-bearing guide for torque protection. It supports an ambient temperature range of -10 to 60 °C, accommodates inductive and proximity sensors for position detection, and incorporates a through, hollow piston rod variant.

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.
