The American Bimba FM-0915-4R is a double-acting cylinder from the Flat-I® ultra-thin series, featuring a metric design. It has a bore diameter of 27 mm, a stroke of 15 mm, and a thickness of less than 12 mm, saving up to 50% in installation space. The anodized aluminum body is paired with a stainless steel piston rod, and it incorporates a self-lubricating composite seal internally. It offers a maintenance-free lifespan of over 5,000 km under operating conditions of 0–0.7 MPa and -20 to 80 °C. The M5 sensor slots on both sides allow for the installation of magnetic reed switches, and the front end offers optional external or internal threads for easy direct installation or use with adapter plates. This cylinder is suitable for precision automation scenarios requiring short strokes and high-frequency responses, such as high-density fixtures, electronic component pressing, and label application.
