Pneumatic cylinder cushioning system

The PPS self-adjusting pneumatic cushioning system adapts automatically to provide suitable cushioning characteristics within the permissible range. It enables fast but gentle travel into the end positions without the need for manual adjustment. This is achieved by the use of longitudinal slots which allow the air to escape in a controlled manner.

Adjustment by the user is no longer necessary, so the commissioning process of many applications is completed with more ease and in much less time, thus reducing installation costs. It also prevents the expensive damage and production downtime which can occur when adjustments to traditional cushioning systems are made incorrectly. The system is also equipped to adapt quickly to changing loads or pressure conditions, should this occur in application.

The self-adjusting cushioning system is now available as an option on the DSNU range of cylinders. It is recommended in all cases where high masses and/or speeds are present and adjustable end-position cushioning is required in order to obtain a jolt-free approach to end positions.
