Pneumatic Seal V6
The profile V6 pneumatic cushioning seal is specially designed for cushioning pistons in pneumatic cylinders.
• No mechanical check valves required since their function is performed by the cushioning rings.
• Optimum use of design-related cushion travel.
• Immediate response to reversed direction thanks to incorporated venting channels.
• Good wear resistance.
• Easier installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Short axial assembly length.
• Short radial assembly depth.
• Installation in closed and undercut housings.
| Range of application | |
| For pneumatic cylinders with end-position cushioning | |
| Operating pressure | ≤ 16 bar 1) |
| Operating temperature | -30 °C to +80 °C |
| Sliding speed | ≤ 1 m/s |
| Media | Compressed air, both lubricated and oi free (after greasing for fitting) |
Installation
For the cushioning spear (Ø d) we recommend a surface finish of Rt = 2 to 3 µm with flattened or polished process traces. The groove bottom (Ø DH11) should not exceed surface finish of Rt = 10 µm with flattened or polished traces.
