The Bosch Rexroth BRAKING ELEMENT KBH 5505 BS1A (R181054021) is a robust hydraulic braking unit designed for use with SNS roller guide rails. This high-performance braking element is engineered to provide dynamic and static stabilization in the axial direction, ensuring reliable operation in various applications. Its compact design makes it compatible with DIN standards, allowing for easy integration into existing systems. The KBH 5505 BS1A features an integrated all-around sealing system and employs special pressure diaphragm technology to maintain maximum functional reliability without pressure losses or leakage. The brake shoes are designed with integrated positive-locking, large-surface contact profiles that contribute to the unit's exceptional axial rigidity and high positioning accuracy. This super heavy-duty model is capable of enduring up to 2 million clamping cycles and can handle up to 250,000 emergency braking operations. Its solid, rigid steel housing is chemically nickel-plated for durability and resistance to harsh conditions. The unit operates with a release pressure of 50 bar and has a low displacement value. The hydraulic braking element can be used across various profiled rail systems including sizes A, B, E, H, N, and S. It features threaded connections on both sides for the hydraulic linkages. The permissible ambient temperature range for operation spans from -20°C to +80°C. The nominal size of the KBH 5505 BS1A allows it to deliver a substantial holding force while maintaining a height compatible with runner blocks across different rail sizes. In terms of maintenance and inspection, the unit is designed for ease with requirements stipulated in ISOVG 32 standards. The functional principle of this hydraulic braking element relies on applying hydraulic pressure (250 bar) through a piston mechanism that clamps onto the roller guide rails flanks while decompression occurs via spring force for efficient cycle times.

Additional information
Hydraulic connections
The hydraulic clamping elements 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 rigidly designed according to its load and requirements. If there is tilt of the clamping elements, 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 serve any guide function. Therefore, it is not possible to replace a roller runner block with a clamping element. The ideal position of the clamping element lies between two roller runner blocks.
When using several clamping elements, these should be distributed evenly on both roller guide rails in order to attain a maximum rigidity of the overall construction.
Lubrication
When using the prescribed printing 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 the components have failed dangerously.
