Optimum performance from clean guide rails
Second quarter 2006
Other technologies
THK's new Laminated Contact Scraper (LaCS), specifically designed for use in conjunction with the company's renowned LM guides and Caged Ball technology, removes foreign objects and liquids from guide rails for increased operating life which is currently measured at 300% on continual life tests.
This scraper system from linear technology specialists, THK, facilitates high-speed, low-maintenance linear motion in harsh or aggressive operating environments. The new scraper features a three-layer design that makes permanent contact with the rail, ensuring dirt, debris, oil and liquids are effectively removed as the carriage moves along the guide rail. The LaCS, attached to the guide's end seal lip, protects it from wear and tear and removes up to three times more debris, significantly extending the operating life of the linear motion system.
Crucially, the LaCS makes use of a self-lubricating synthetic rubber triple layer foam that minimises resistance and maintains the high-speed performance associated with Caged Ball designs. As a result, the new LaCS is an advantageous accessory for a variety of linear motion guides used in hostile or aggressive operating environments, including injection-moulding equipment, machine tools and high-speed transfer systems.
Supporting THK's low maintenance philosophy, the new LM guide scraper prevents liquids entering the LM block and reduces abnormalities caused by abrasive foreign objects. It is also possible to supplement the LaCS with a specially designed metal scraper that removes larger foreign objects such as cuttings and swarf.
The highly adaptable LaCS can be used to clear the way for virtually the full range of THK LM guides, including those featuring the highly acclaimed Caged Ball technology. The result is a low-maintenance, high-speed guide capable of an extended operating life in arduous conditions. SKF South Africa is the sole agent for the THK product range in Sub-Sahara Africa.
