Linfinity Plus

Highly Efficient Anti-Backlash Linear Actuator Tool

Lin Engineering has innovatively pushed the boundaries of linear actuator technology by patenting an advanced design named Linfinity Plus. Linear actuators, being crucial to various industrial and scientific applications, demand utmost precision and reliability, which often gets compromised due to a common issue known as backlash. This unintended movement during the reversal of the actuator's direction compromises its positioning accuracy and repeatability. Lin Engineering's patented Linfinity Plus is imbued with a sophisticated suite of anti-backlash features, revolutionizing the linear actuator design.

Linfinity Plus Advantages

The Linfinity Plus nut is a highly advanced technology that boasts numerous features, including:

  • Self-Lubrication
  • Reduced Radial Play
  • Increased Thrust Capability
  • Bi-Directional Tension Anti-Backlash
  • Adjustable Preload 
  • Low Drag Torque
  • Extended Stroke Length
  • Enhanced Repeatability
  • Low Noise
  • Superior Heat Dissipation

Another important feature of the Linfinity Plus nut is its adjustable preload, which allows users to adjust the level of backlash reduction based on their specific application requirements. This feature provides maximum flexibility and control, enabling users to optimize their linear actuator performance for a wide range of applications. 


The Linfinity Plus anti-backlash nut can be applied to captive-style actuators and allow for extended stroke length over traditional designs, enabling it to perform a wider range of tasks.

Linfinity Plus Applications

The Linfinity Plus nut can be used in various industrial and scientific applications where linear actuators are employed. Some examples of applications where the Linfinity Plus nut can be used include: 

  • Medical Devices
  • Laboratory Equipment 
  • Automation Systems
  • Robotics 
  • Aerospace
  • Precision Manufacturing

Essentially, any application where precise positioning, accuracy, and repeatability are critical can benefit from the advanced anti-backlash capabilities offered by the Linfinity Plus nut.
