Description

B1.282 Hydro-cylinder with optional stroke end cushioning

Double-acting hydro-cylinders with connecting dimensions according to DIN ISO 6020. Only exception is the shorter overall length. On request also available in the longer version as per DIN ISO 60 20. The piston rod is provided with an external thread. For fixing, the front and back part of the body is provided with 4 internal threads.
The adjustable stroke end cushioning avoids a too hard stop of the piston in the cylinder body with the following applications:

1. High piston speed

2. Additional load at the piston rod

3. If an external stop cannot be provided to compensate the additional load

Application examples

Application example 1

Injection mould

Cycle (portrayed in simplified terms)
1. Mould closed, injected
2. Toothed rack retracts, threaded spindle is moved out
3. Limit switch gives signal "open mould"
4. Mould opens
5. Workpiece will be ejected
6. Mould closes
7. Toothed rack extends, threaded spindle is moved in
8. Limit switch gives signal „Substance to be injected“
9. Substance is injected
1. New cycle
