Festo
175861
Swivel/linear unit DSL-40- -270-P-S20-CR
The Festo 175861 is a double-acting rotary vane industrial component featuring a 40 mm piston diameter, a 240 deg swivel angle, and a 270 deg rotation angle adjustment range with a 1.5 deg fine adjustment. Designed with a plain-bearing guide for torque protection, a hollow through piston rod (S20 variant), and a stroke capacity of 10 to 200 mm, this unit delivers 20 Nm of torque at 6 bar operating pressure. It is equipped with right-side shock absorber cushioning (CR) alongside flexible cushioning rings or plates at both ends (P), a 15 deg cushioning angle, and 12 mm cushioning length to handle a maximum impact speed of 500 mm/s and a max swivel frequency of 0.7 Hz at 6 bar. Position detection is supported for both inductive and proximity sensors, operating within a -10 to 60 deg C ambient temperature range on dried compressed air at 2.5 to 8 bar in any assembly 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.
