Festo
185934
Rotary actuator DSM-8-90-P-FW
The Festo part number 185934 is a double-acting industrial component featuring a rotary vane structural design with a size 8 specification and an adjustable swivel angle from 0 degrees to 90 degrees. Operating within a pressure range of 0.35 MPa to 0.8 MPa, this unit utilizes elastic cushioning rings at both ends with a 0.5-degree cushioning angle and achieves a repetition accuracy of 1 degree at a maximum swivel frequency of 3 Hz at 6 bar. It operates with compressed air as per ISO 8573-1:2010 [7:4:4] and maintains ISO 14644-1 cleanroom suitability of class 6 within an ambient temperature range of 0 degrees C to 60 degrees C.

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.
