General product information | Ball rail systems 5 Pneumatic clamping and braking elements UBPS also in sizes 45 and 55: ▶▶ Very high axial holding forces of up to 7,700 N at a release pressure of 5.5 bar with high level of spring energy storage. ▶▶ Compact design, compatible with DIN 645

Ball rail systems | General product information Product description Characteristic features With interchangeable elements ex store, you can combine complete guide units yourself ... At Rexroth, we manufacture ball guide rails and ball runner blocks in ball raceways in particular so precisely that it is possible to interchange each individual element at any time. This means that you can combine them in any way you like within each accuracy class. As a result, you have top level logistics that are unique. Each element can be individually ordered and separately stocked. Both sides of the guide...

General product information | Ball rail systems 7 Further highlights ▶▶ Interchangeability with the roller rail system ▶▶ Integrated, inductive and wear-free measuring system as an option ▶▶ Extensive range of accessories ▶▶ Attachments on the ball runner block for mounting from above and below1) ▶▶ Increase in rigidity with lift-off and lateral loading by means of additional screw connections on two drilled holes in the middle of the ball runner block1) ▶▶ Mounting threads provided on end faces for fixing of all add-on elements ▶▶ High rigidity in all load directions – permits applications...

Ball rail systems | General product information Notes General notes ▶▶ Combining different accuracy classes When you combine ball guide rails and ball runner blocks of different accuracy classes, the tolerances change for dimensions H and A3. See “Accuracy classes and their tolerances” ▶▶ The ball rail systems are linear guides capable of absorbing forces from all transverse directions and moments about all axes. The ball rail system is intended exclusively for guiding and positioning tasks when installed in a machine. ▶▶ The product is intended exclusively for professional use and not for...

General product information | Ball rail systems 9 Rexroth BHSP ball rail systems are suitable for dynamic linear applications requiring reliability and precision. The machine tool industry and other sectors must observe a series of standards and directives. These requirements can vary significantly worldwide. It is therefore essential to understand the legislation and standards that apply in each particular region. EN ISO 12100 This standard describes the safety of machinery – general principles for design, risk assessment and risk reduction. It gives a general overview and contains a guide...

Determination of the dynamic load capacities and moments is based on a travel life of 100,000 m per ISO 14728-1. Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt and ML by 1.26 according to the table. 1) Ball runner blocks without ball chain. 2) Ball runner blocks with ball chain. 3) Steel: All steel parts made of carbon steel. 4) Resist NR Size 15 - 35: Ball runner block body made of corrosion-resistant steel per EN 10088. 5) Resist NR II: All steel parts made of corrosion-resistant steel per EN 10088. 6) Resist CR: Ball runner block body made of steel...
