The Bosch Rexroth KBH 4505 AS1A (R161944021) is a hydraulic braking element designed for precision and reliability in demanding applications. This braking unit is compatible with all SNS ball guide rails, ensuring versatility across various rail sizes including B, H, E, A, S, and N profiled rail systems. It boasts a robust construction with a solid steel housing that is chemically nickel-plated for durability and resistance to harsh conditions. The KBH 4505 AS1A operates efficiently with a hydraulic pressure of up to 250 bar for clamping and braking operations, while a pretensioned return spring facilitates rapid decompression cycles. This model is engineered to deliver high positioning accuracy and can endure up to 10 million clamping cycles and up to 250,000 emergency braking operations without compromising performance. The release pressure is set at 50 bar, which contributes to the safety and control of the system. An integrated all-around sealing coupled with special pressure diaphragm technology ensures maximum functional reliability by preventing pressure losses or leakage. The brake shoes feature integrated positive-locking with large-surface contact profiles that provide maximum axial rigidity, contributing to the unit's super heavy-duty capabilities. The KBH 4505 AS1A has been designed for low displacement volume during operation and supports a high holding force that maintains stability under load. Additionally, it has threaded connections on both sides for easy integration into hydraulic systems. With its compact design conforming to DIN standards, this braking element from Bosch Rexroth offers an exceptional solution for applications requiring precise motion control and significant holding power in automation and linear motion systems.

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.
