The Bosch Rexroth COVER MKK-080-NN-3 (R117510122) is a state-of-the-art linear module that is part of the latest MKXXXXNN product generation, offering enhanced performance features in a compact and backward-compatible format. This ready-to-install guide system is equipped with an extremely compact aluminum profile, which houses an integrated Rexroth Ball Rail System. The carriage, crafted from aluminum, offers options for T-slots or threaded holes for versatile mounting capabilities and includes centering holes for precision. The drive mechanism of the COVER MKK-080-NN-3 consists of a precision Ball Screw Assembly (BASA) in rolled design, which can be selected in tolerance grades T5 or T7 according to ISO standards. This assembly provides zero-clearance due to its cylindrical single nut design. The unit can be further customized with individual lubrication options suitable for connection to one-point lubrication systems. Additional features include an integrated measuring system (IMSA), which eliminates inaccuracies caused by parallelism offsets between the measuring system and the guide system. This fully integrated component simplifies installation and maintenance while ensuring high precision. The unit also supports high speeds over lengths up to 5400 mm with optional screw support pairs (SPU) that are maintenance-free and protected by sealing strips. The structural build of the COVER MKK-080-NN-3 comprises anodized aluminum frames, carriages, and end blocks with antifriction bearing steel components such as the Ball Guide Rail and Ball Screw Assembly. For environments requiring additional corrosion resistance, certain elements feature a matte silver finish or hard chrome plating known as Resist CR/NR coatings. Lubrication variants are tailored to specific needs: LSS for factory-applied initial lubrication; LPG for modules shipped without initial lubrication but with corrosion prevention; LCF prepared for central liquid grease lubrication systems; and LCO designed for oil lubrication systems. As part of its extensive attachments accessories program, this linear module offers proximity or mechanical switches, clamping fixtures, sliding blocks, connecting shafts, cable ducts made from aluminum profiles, and connection technology compatible with Linear Motion Systems. Depending on the model within the product generation MKXXXXNN series, protective coverings range from plastic strips to bellows. In summary, the Bosch Rexroth COVER MKK-080-NN-3 (R117510122) represents a highly precise linear motion solution that integrates advanced features like IMSA measuring systems and SPU screw supports into its robust structural design suitable for various applications requiring high positioning accuracy and repeatability.
