Perimeters for Vision Tests with Self-Lubricating Screws, Slides & Plastic Nuts

Application Overview:

• What was needed: Perimeter, i.e. devices that measure the field of view and determine the sensitivity of the visual system
• Requirements: 100% self-lubricating and maintenance-free, hygienic for the medical sector, small installation space
• Products used: drylin® N flat guides, dryspin® trapezoidal lead screws with matching lead screw nut
• Success for the customer: A perimeter that easily meets hygienic requirements. Thanks to the igus solution, self-lubricating adjustments are guaranteed and no maintenance is required. Dust and dirt can't stick.

All individual components used in medical devices must meet special requirements. Use in hygiene-sensitive areas is always special. In medical technology, metallic lead screw nuts continue to be the norm. However, they mostly require frequent maintenance and lubrication. In this process, dust and dirt particles can easily stick to the used lubrication. This leads to considerable contamination and a significantly higher wear compared to a system that works in dry operation.  Furthermore, the metallic lead screw nuts can corrode quickly in humid environments.
