Screw-in cylinders ∣ FAQ
What is a hydraulic screw-in cylinder and how does it work?
A hydraulic screw-in cylinder is a very compact and integrable version of a hydraulic cylinder. The name “screw-in cylinder” describes the special mounting method of this cylinder. It is screwed directly into the fixture/tool body and finishes flush with the surface of the fixture or tool. The cylinder has no pipe thread connections. Instead, the pressure medium is supplied directly through bores in the fixture/tool body. By means of deep hole drilling, the cylinders can therefore also be connected in series in a very compact manner.
The (double-acting) cylinder is very compact in design and consists of a cylinder housing in which the piston is located. The cylinder housing contains bores for the rod-side supply of the pressure medium (return stroke). The cylinder bore itself acts as a stop for the return stroke. For the forward stroke, the cylinder is pressurized on the piston side.
What applications are screw-in cylinders typically used for?
Screw-in cylinders are used in a wide range of industrial applications. They are particularly used in applications that require a very compact and/or integrated design. They are screwed directly into the fixture or tool body and are fully recessed into it.
Application areas of screw-in cylinders are:
- Mechanical engineering
- Fixture construction
- Mold making
- Plant engineering
- Handling technology
- Manufacturing technology
What types of operation are there for screw-in cylinders?
Our screw-in cylinders are designed as double-acting cylinders. This means that both extension and retraction of the piston are carried out hydraulically. The pressure medium is supplied directly via drilled channels in the fixture or tool body. Due to the design of our cylinders, there is a certain flexibility in the positioning of the supply bore when creating the bore for the piston forward stroke.
What connection and mounting options are available for screw-in cylinders?
The hydraulic screw-in cylinders are not connected to the hydraulic circuit (as is often the case) via pipe thread connections and pipes/hoses. Instead, the pressure medium is supplied directly through drilled channels in the fixture or tool body. By means of deep hole drilling across multiple screw-in bores, several cylinders can be very easily connected hydraulically in series.
Our hydraulic screw-in cylinders are very compact elements. As the name “screw-in cylinder” suggests, this cylinder is screwed directly into the fixture or tool body. Additional mounting elements such as screws or locknuts are not required. After installation, the cylinder finishes flush with the top surface of the fixture / tool.
Which customized special designs are possible?
Our hydraulic screw-in cylinders can be supplied as customized special designs in series on customer request. From piston Ø 16 mm to Ø 63 mm and strokes up to 100 mm, many customer-specific requirements can be realized.
Typical special designs are:
- special housings
- special strokes
- special pistons
The cylinders can also be supplied with chrome-plated and/or inductively hardened piston rods. Special materials and sealing materials are also used on customer request. Galvanic coatings are also possible on customer request.
Hydraulic screw-in cylinders from Germa GmbH – double-acting cylinders for high flexibility and efficiency in fixture construction, tool making and mold making as well as in general mechanical engineering
With 6 sizes, two stroke variants and optionally internal or external thread on the piston rod, this cylinder series offers a wide range of options. The selection between NBR or FKM seals ensures application-oriented and durable sealing.
The easy-to-create installation bore, the simple assembly using a face spanner, as well as the extremely compact design make this product particularly user-friendly. The flexibly positionable bore for the forward stroke enables greater design freedom in construction.
The hydraulic screw-in cylinder “type 200” not only impresses with its versatility, but is also optimally designed for the requirements of compact multiple clamping. When integrating several cylinders into the fixture body, deep hole drilling enables a line-free pressure oil supply.
For fixture construction, tool making and mold making as well as general mechanical engineering, the hydraulic screw-in cylinder “type 200” is the ideal solution. In the case of multiple hydraulic cylinders, deep hole drilling enables a line-free pressure oil supply – for maximum efficiency and precision in your application.
