Shock absorber DYEF-M12-Y1

The Festo 1179840 is an M12 industrial component featuring a 1.2 mm stroke and a product weight of 45.5 g, equipped with elastic cushioning rings at both ends without a fixed metal stop. Constructed with a high-alloy steel housing, NBR seals, and a locknut for mounting, it operates within an ambient temperature range of 0 °C to 60 °C while withstanding a maximum impact velocity of 0.8 m/s and providing 0.35 J of maximum energy absorption per stroke. This RoHS-compliant unit achieves corrosion resistance class 2 for moderate corrosion stress and VDMA24364-B1/B2-L LABS conformity for any mounting position without position sensing.

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.
