Bosch Rexroth AG Integrated Measuring System for BRS and RRS R310EN 2350 (2007.07) Product Overview Rexroth Ball Rail and Roller Rail Systems can be supplied with an integrated, inductive linear measuring system. This development combines the guiding and measuring functions in one unit and opens up new opportunities in machine design. In a word: Mechatronics in practice Highlights: Integrated Measuring System The guide system and the measuring system form one unit, building on standard guide elements. No additional space is required, except possibly in the longitudinal direction to...

R310EN 2350 (2007.07) Integrated Measuring System for BRS and RRS Bosch Rexroth AG Integrated Measuring System for Ball and Roller Rail Systems Same mounting hole pattern as standard runner blocks Installation requirements: Scanner fastening screws must be accessible and there must sufficient clearance at the end of the rail for pulling the scanner off. Adapter plate allows scanner to be replaced during servicing (by Rexroth service engineers) without removing the runner block.
