The article is an overview of various materials used in power hydraulics for basic hydraulic actuators components such as cylinders, cylinder caps, pistons, piston rods, glands, and sealing systems. The aim of this review is to systematize the state of the art in the field of materials and surface modification methods used in the production of actuators. The paper discusses the requirements for the elements of actuators and analyzes the existing literature in terms of appearing failures and damages. The most frequently applied materials used in power hydraulics are described, and various surface modifications of the discussed elements, which are aimed at improving the operating parameters of actuators, are presented. The most frequently used materials for actuators elements are iron alloys. However, due to rising ecological requirements, there is a tendency to looking for modern replacements to obtain the same or even better mechanical or tribological parameters. Sealing systems are manufactured mainly from thermoplastic or elastomeric polymers, which are characterized by low friction and ensure the best possible interaction of seals with the cooperating element. In the field of surface modification, among others, the issue of chromium plating of piston rods has been discussed, which, due, to the toxicity of hexavalent chromium, should be replaced by other methods of improving surface properties.

This paper deals with process of remanufacturing which is a process that is applied to products have expired or have been damaged, so the products can be reused with almost the same quality and balance as new products. PT UTR plant Jakarta has a new project, namely remanufacturing PT MCG's hydraulic cylinder. To maintain customer trust, each component that is remanufacturing must be ensured of its quality by means of testing before being sent to the customer. This equipment is made based on the use of management methods that have been standardized, namely 7++ ups tools. In collecting the required data, a direct approach was taken by following the existing remanufacturing process flow, so that the tool to be made was really useful and easy to use. From the results of the research carried out, we make a special equipment of a stand test bench hydraulic cylinders so that each component of the hydraulic cylinder that was remanufacturing could be done on a test bench. With this equipment, the quality standards of remanufacturing hydraulic cylinders can be accounted for.
