SMCCM2G25-100Round Body Air Cylinder, 25 mm Bore, 100 mm Stroke, Double Acting, Rc1/8 Ports, Flange Mount

Product Description

What this part is

SMC CM2G25-100 pneumatic cylinder from the CM2 series. The CM2 is SMC’s round-body double-acting single-rod air cylinder, built with a rolled tube barrel rather than a tie rod frame. Manufacturer: SMC. Part Number: CM2G25-100. Series: CM2. Bore: 25 mm. Stroke: 100 mm. Actuation: double acting, single rod. Port Size: Rc1/8. Maximum Operating Pressure: 1.0 MPa. Proof Pressure: 1.5 MPa. Medium: compressed air. Body Style: round body, flange mounted.

Decoding the designation

CM2 — SMC’s CM2 round-body air cylinder series, published in 20, 25, 32 and 40 mm bores.

G — the flange mounting style within the CM2 range.

25 — 25 mm bore.

100 — 100 mm stroke.

CM2G25100 and CM2 G25 100 are the same part number without and with spacing.

What these specs mean in practice

Bore: 25 mm. Maximum Operating Pressure: 1.0 MPa. A 25 mm piston at 0.5 MPa develops roughly 245 N on the extend stroke, which places the cylinder in the light clamping, feeding, ejecting and gate-actuation band. Proof Pressure: 1.5 MPa. The proof figure is the pressure the body is tested to, a 50 per cent margin over the working ceiling. Stroke: 100 mm. Port Size: Rc1/8. Body Style: round body. A rolled round barrel is lighter and smaller in cross-section than a square tie rod cylinder of the same bore, which is what makes the CM2 the standard fit where an actuator has to slot between other machine members. Actuation: double acting. Both directions are powered, so the retract stroke can do work rather than merely reset.

Mounting data

Port Size: Rc1/8. Bore: 25 mm. Mounting Style: G, flange. The CM2 series shares one envelope per bore across its mounting styles, so a CM2 of the same bore and stroke in a different mounting letter has the same barrel, rod and porting on a different bracket.

Quantity and configuration

Unit Quantity: 1 Pc. One complete cylinder per listing.

Condition

Condition: New, open box.

Interchange guidance

CM2G25-100, CM2G25100 and CM2 G25 100 are the same part number. SMC CM2 numbers read series, mounting letter, bore, then stroke, so CM2G25 numbers differing only in the trailing figure differ only in stroke, and CM2B25-100, CM2L25-100 and CM2F25-100 are the same 25 mm bore and 100 mm stroke cylinder on a different mounting style.
