The IML/HDL/PKL ball screws range are high dynamic and high load ball screws for injection molding machines, presses and other heavy duty applications operated by electric servodrives which may reach extreme working condition requirements.

Main Features:

  • Top results with high durability and reliability.
  • Especially high values of dynamic and static load capacity, as well as high values of maximum permissible loads.
  • Very smooth rotation ensuring uniform ball circulation, avoiding any crashes between balls and resulting in very low noise levels and enabling the use of higher feed speed values, thus reaching DN values up to 170.000.
  • Accuracy grade and axial play:
    • H 0.020 mm or less.
    • A 0.040 mm or less.

Depending on the application requirement of load capacity and speed, and in order to obtain the optimum life results in each case, SHUTON-IPIRANGA has developed three different types of HIGH LOAD ball screws:

IML high load technology

      • It is designed for high load and high speed applications with DN up to 170.000.
      • It is indicated when there is a high load resulting in high average force and at the same time medium and high speeds, resulting in a medium to high average speed.
      • IML technology enables working temperature to be kept controlled.

HDL high load technology

      • It is designed for very high load and moderate speed applications with DN up to 110.000.
      • It is indicated when there is a high load, resulting in high average force, and at the same time low speeds, resulting in a low average speed.
      • It is the option that gives a greatest dynamic, static load and rigidity.

PKL high load technology

        • It is designed for applications with momentary extreme peak loads, where the average force does not have to be particularly high.
        • Possibility of high speed, both in peak speed as in average speeds.

Optimized ball screw design by study of:

      • Type of HIGH LOAD design.
      • Shaft and nut thread geometry.
      • Ball circuit distribution and position.
      • Number of thread starts.
      • Load distribution in HIGH LOAD ball screws.
      • Tying method.
      • Lubrication.

Nut detail: HIGH LOADS TS single nut (with 1 or 2 starts), with ball recirculation by U-type or B-type recirculation system.
