Manufacturer: Nippon Gear Co., Ltd.
Model: LSB Series

Features

• Small and Light

  ・Top-class compact model of mechanical actuators.
  ・Can be installed in small spaces.

  Elevated maintenance accessibility

  ・Significantly simplified the structure to enhance maintainability.
  ・Settings made easier by adopting new torque switches and geared limit switches.

  Highly durable gear

  ・The worm gear and worm are made of aluminum bronze and chrome molybdenum steel.
  ・Optimal materials for each gear are chosen based on the load, and high-pressure grease is filled inside the sealed gear case.

  Overwhelming Tolerance for Torque

  ・Achieving world-class tolerance for torque compared to its small body.

  Newly designed High-Performance Torque Switch

  ・Capable of setting the operating point across the entire torque range for both opening and closing directions. Ensures reliable protection of the valve from overload.
  ・Implemented a high-precision reverse switch structure to address concerns of wear and tear.

  Newly designed High-Precision Geared Limit Switch

  ・Adopts the snap action of a micro switch to prevent contact welding and enhance reliability.
  ・Allows setting the operating point at any position across the entire stroke.
  ・The switch rotor operates reliably with a metal intermittent gear, ensuring that the set position remains unchanged.
