Product description
Functional principle
Hydraulic pressure: 50 - 150 bar
Clamps and brakes with pressure
The large-scale clamping profiles are pressed directly by the hydraulic oil onto the flanks of the Ball Guide Rail via a piston principle.
Hydraulic pressure: 0 bar
Decompression with spring force
A pre-tensioned return spring allows for short decompression cycles.

Project planning information
Additional information
Hydraulic connections
The Hydraulic Clamping Units are pre-filled with HLP 46 at the factory. The hydraulic connection is attached on two sides.
One connection is suitable for the application. Take care when venting the fixed and flexible hydraulic lines, because air connections can damage the sealing elements.
Connection structure, mounting the clamping elements
To prevent detrimental effects, e.g. permanent grinding on the linear guide, the connection structure must be rigid and in accordance with its load and requirements. If the clamping elements are tilted, this can result in contact, wear and therefore damage to the linear guide.
The setting at the factory is adapted for the linear guide and may not be altered during assembly.
It is imperative to observe the mounting instructions for the clamping and braking units and the linear guides.
Some spring-loaded accumulators are equipped with a transport lock between the contact profiles.
This must be removed during assembly by means of pressurization of the element. When the pressure is removed, the transport lock or the associated linear guide must always lie between the contact profiles.
The clamping elements do not have any guiding function. Therefore, a runner block cannot be replaced with a clamping element. The ideal position of the clamping element is between two runner blocks.
When using several clamping elements, these should be distributed evenly on both Guide Rails in order to attain maximum rigidity for the overall construction.
Lubrication
When using the prescribed pressurizing medium, lubrication is not required.
Surface finish protection
All housings of the clamping elements are chemically nickel-plated and therefore have limited rust protection. Aluminum subsections are chemically nickel-plated according to their requirement.
B10d-value
The B10d-value specifies the number of switching cycles until 10% of components fail dangerously.
Mounting
Note for mounting
- Stop surfaces can be used on two sides.
- Make sure the connection structure is rigid.
- Observe the mounting instructions prior to commissioning.
- Check whether the sealing lips of the front seals rest evenly on the Ball Guide Rail. Realign if necessary.
Maintenance
Notes on lubrication
- Initial filling of hydraulic oil HLP46
- Check for compatibility when using different oils
