Semi-rotary actuator DSMI-63-270-A-B

The Festo 1202485 is a double-acting industrial component featuring a rotary vane design with a ball-bearing drive shaft and a 63 mm piston diameter. It offers a swivel angle of 0 to 272 degrees with a rotation angle adjustment range of 0 to 270 degrees, flexible cushioning rings or plates at both ends, and an integrated analog displacement encoder for position detection. Operating at a working pressure of 4 to 8 bar, this unit achieves a maximum travel speed of 2,000 deg/s and a minimum travel speed of 50 deg/s.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
