LinFinity Linear Actuator Systems

[vc_row][vc_column][vc_column_text]The LinFinity Linear Actuator is a system engineered to eliminate issues that plague ordinary linear actuators:

• Excessive friction and heat build up
• Too much noise
• Degrading accuracy
• Short life span
• Required maintenance
• Patented Design

The LinFinity Linear Actuator system is composed of a patented  LinFinity Nut, a highly polished lead screw, and a Lin Engineering stepper motor.

1. Lin Finity Nut

The LinFinity Nut is an internally lubricated anti-backlash nut proven to last over 12 million inches of travel in a typical application without maintenance.

The patented design incorporates an internal grease reservoir which distributes a consistent layer of grease throughout the entire surface of the lead screw as the nut travels. The internal reservoir maintains hydrodynamic lubrication throughout the life of the product, which drastically reduces friction and thus increases the performance and longevity of the product.

Ordinary externally lubricated anti-backlash nuts act as a wiper: instead of distributing the grease evenly, they tend to push the grease out to the edges of the screw. This results in the grease drying out and ultimately leads to product failure.

Reduces Heat Build Up

Less friction means less heat is being generated. LinFinity reduces heat build up by at least 20% compared to the closest competing design. Heat leads to premature failure.

Reduces Noise

Ordinary externally lubricated nuts
tend to increase friction throughout
the life of the product. Friction causes
excessive noise. LinFinity maintains
low friction throughout the lifespan and
does not generate more noise with age.

Extends Life

Lower heat and reduced friction along with even distribution of grease result in the overall life of the Linear Actuator system to increase.

2. Leadscrew

PTFE coated leadscrews are often used to reduce friction. This function well in many applications, however, PTFE coating may not be suitable for certain applications which demand constant cycling.

We’ve experienced noticeable coating damage while constantly cycling an anti-backlash nut over a PTFE coated leadscrew. The damage often occurs within one million inches of travel. And once the coating is compromised, further damage occurs at accelerated rate. This occurs because the metal surface of the leadscrew has to be roughened to accept the PTFE coating. And when the coating fails, the anti-backlash nut is exposed to the rough surface of the metal, which in turn accelerates the wear of the nut.

The LinFinity Nut glides on a highly polished leadscrew on a thin layer of grease. This makes LinFinity Nut suitable for even the most demanding applications. Polished leadscrews lets us achieve over 12 million inches of travel with no maintenance required; more than any other product we’ve tested.
