Rexroth is expanding its product range to include pneumatic bellow actuators in the BCS and BCE series. Bellow actuators do not have a piston rod, reducing the installation height. The actuators are resistant to weather and many environmental influences. The new epichlorohydrin rubber makes the BCE series bellows resistant to media, acids, and oil, as well as many chemicals such as acetone, fuels, and grease. The bellows have no mechanical friction surfaces that move against one another, as is the case with seals. This means that the cylinder is wear-free even under adverse environmental conditions involving dirt, dust, granulate, and mud. Thanks to the new epichlorohydrin rubber, the latest BCE series bellow actuators from Rexroth can be operated in a temperature range from -20C to +130C. The cylinders in the BCS series are equipped with a passivated plate made of 1.4301 stainless steel. This cylinder is resistant to corrosion and acids, as well as many detergents, and is thus suitable for use in the food industry, offshore applications, and the pharmaceutical and process industries. The bellow actuators in the BCE series are available with working diameters of 150mm to 385mm; those in the BCS series come with diameters of 150mm to 400mm. Strokes of up to max 273mm are possible, depending on the series. Forces of 0 to 71.2kN are possible with the product range. Depending on the type, bellow actuators can be used for angles of tilt that are up to 30 degrees.
