Profile: Air Power and Hydraulics Ltd designs and manufactures custom hydraulic cylinders, actuators and power units. Our C10 industrial cylinders are ideally suited to the majority of general engineering duties. They are used extensively throughout the material handling industry. K10 and K20 high-pressure hydraulic cylinders are a development of the APH C10 and CEPAC ranges. The design and mounting styles are comparable to the CEPAC cylinders so that the designer can incorporate this new generation of APH cylinders into machinery where high power to weight (and space) ratios are mandatory.. The high strength alloy steel barrels, stainless steel/chrome plated rods, aluminum bronze pistons and glands combine to make these cylinders attractive for specialised marine and sub-sea duties.
