THK Introduces Low Cost, High Efficiency Actuator Type VLA

Schaumburg, IL - (February 10, 2005) THK's new Type VLA Actuator has fewer components and a lower overall cost, by using a THK LM Guide for its base.

Long-term cost savings are also realized through the Type VLA's incorporation of patented Caged Technology, a QZ Lubricator, and electro-mechanical components.

The VLA uses THK's compact Type SRS LM Guide featuring patented Caged Technology. This technology separates rolling elements with a synthetic resin cage that retains grease, and reduces maintenance costs. To ensure optimal lubrication within the ball screw unit, THK incorporates its QZ Lubricator. The introduction of the Type VLA replaces pneumatic cylinders in many applications. The VLA's electro-mechanical components offer improved energy efficiency, as well as cleaner and quieter operation. Contamination from lubricants, audible noise and damaging friction are greatly reduced.

While cost-efficiency is a key advantage to the Type VLA, performance parameters too, should be noted - the VLA's high speeds produce maximum operating efficiency.

The Type VLA is available in slide and cylinder types, and is compatible with most popular AC or DC servomotor controller packages.

Rated speeds on the Type VLA actuators range from 300 mm/s to 600 mm/s; ball screw leads are from 6 mm to 12 mm.
