Product description
Table part
On table parts with an integrated clamping unit, a standard air connection (1) is located opposite the lube nipples. Connection to an air connection is sufficient.
Clamping unit (LKPS)
The clamping unit is used exclusively for clamping linear axes (static holding)
Owing to the spring energy accumulator, it is closed in the deenergized condition (NC).
The clamping unit is usable as a proven component in connection with a suitable function test and in category 1 controls as per DIN EN ISO 13849-1:2006.
If the user risk assessment determines a Performance Level (see Appendix A, DIN EN ISO 13849-1:2006) requiring a higher category, further technical control measures are necessary for safe holding or for preventing startup from the immobile position.
For further instructions and information, please refer to documentation belonging to this product.
The clamping unit must only be used when the axis is at a standstill.
The clamping unit may not be used as a braking unit!
Use for the emergency braking of a moving weight is not permissible.
Clamping during movement may lead to the destruction of the clamping unit as well as he linear guide!
Technical data
Air pressure: 0 bar
Clamps with spring force
In the event of pressure drop, the clamping profiles are pressed onto the guide rail by a spring energy accumulator.
A quick-release valve for short reaction times is required.
Air pressure: 5.5 - 8 bar
Decompression with air pressure
The clamping profiles are held apart by the compressed air.
- Free movement is possible
