JMR & JSR Series Rack Jacks: High-Speed Bidirectional Drive<\/strong><\/h1>\n

1. Product Overview<\/strong><\/h2>\n

The Rack Jack<\/b> is one of the most versatile actuation devices, capable of seamless bidirectional conversion:<\/p>\n

    \n
  • \n

    Rotary to Linear:<\/b> Converts input shaft rotation into rack travel.<\/p>\n<\/li>\n

  • \n

    Linear to Rotary:<\/b> Converts rack movement back into shaft rotation.<\/p>\n<\/li>\n<\/ul>\n

    Designed to optimize speed and efficiency, this series is the ideal choice for push-pull mechanisms or rapid lifting in confined spaces.<\/p>\n

    2. Key Features of the JMR & JSR Series<\/strong><\/h2>\n
      \n
    • \n

      Superior Linear Speed:<\/b> Enables the rack to move at high velocities even with low input shaft speeds. Maximum travel speeds can reach up to 8000 mm\/min<\/b>.<\/p>\n<\/li>\n

    • \n

      Optimal Mechanical Efficiency:<\/b> With an efficiency rating of up to 0.90<\/b>, these units minimize energy loss during power transmission.<\/p>\n<\/li>\n

    • \n

      Flexible Installation:<\/b> The housing features two mounting surfaces (parallel or perpendicular to the rack’s direction of travel), allowing engineers to integrate the unit easily into various machine structures.<\/p>\n<\/li>\n

    • \n

      Diverse Shaft End Options:<\/b> Offers 3 types of shaft ends to suit any connection requirement. Additional support for bellows (dust covers), limit switches, and RC encoders is available.<\/p>\n<\/li>\n

    • \n

      Safety Note (Non-Self-Locking):<\/b> Due to high efficiency and low friction, this series is not self-locking<\/b>. A braking system must be equipped to hold the position when the load is stopped.<\/p>\n<\/li>\n<\/ul>\n
