Power Cylinder  Worm Series

Product photo
  • Worm series is the perfect power cylinder to replace hydraulic cylinders.
  • Worm Series LPWB provides large thrust by using a high precision worm gear and a highly efficient ball screw manufactured with technology based on nearly a century of manufacturing tradition.
  • Allowable Thrust :49~490kN
  • Nominal Speed :5~72mm/s

Features

  • ・Clean

    There are no hydraulic pumps or pipes, so no worries about oil leakage from the connecting parts.

  • ・Easy installation

    No need for hydraulic pumps and pipes. Can be operated just by connecting a three-phase power source.

  • ・Accurate control

    Changing speeds and accurate positioning are possible by using an inverter.

  • ・Low cost

    Reduces costs by significantly reducing the number of parts.

  • ・High load capacity

    Can be used with large loads like jacks can thanks to its special steel alloy. (The maximum load capacity is 50t in the large thrust zone. )

Application examples

Compact shape that is substantially closer to hydraulic cylinders

  • ・Uses a Tsubaki high precision worm gear for the reducer, and it incorporates a support structure for the ball screw and gear.
  • ・The total length of the unit can be significantly reduced since there is no need for a bracket unlike with traditional power cylinders.
  • ・Main unit mounts with clevises on both ends, which is the most popular method for mounting hydraulic cylinders.

Simplified thrust calculation for hydraulic cylinders

Options

  • ・L:External stroke adjusting limit switch (2)

  • ・R:Rotary encoder

  • ・Y:Counter LS *1

  • ・C:Clevis mounting adapter

  • ・K2, K4:Comes with internal limit switches for adjusting the stroke length.

  • ・J:With Bellows *2

  • ・P:Potentiometer

・Unit can now use a clevis and position detection unit in combination, which was impossible with previous Power Cylinders.

  • ※Allowable thrust is the maximum allowable load of the cylinder.
  • ※Generated thrust is the thrust converted from the motor rated torque.
  • ※With inverter drives, you will need to confirm generated thrust.
  • ※Generated capacity in the above specification list is with a motor time rating of S2:30min and duty factor of 25%ED.
  •  The motor size can be reduced with low frequency operation.
  • ※Models exceeding 294kN(30000kgf) and special combinations are also available in addition to the specifications listed above.
  • ※The drawing is a reference drawing. Dimensions will differ depending on the detailed specifications.
  • ※Contact a Tsubaki representative for more information.
