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
