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

• What was needed: drylin® N flat guides, dryspin® trapezoidal lead screws with matching lead screw nut
• Requirements: 100% self-lubricating and maintenance-free, hygienic for the medical sector, small installation space
• Industry: medical technology
• Success for the customer: A perimeter, a device that measure the field of view and determine the sensitivity of the visual system, that easily meets hygienic requirements. Thanks to igus® products, 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 essential. In medical technology, metallic lead screw nuts continue to be the norm; however, they mostly require frequent maintenance and lubrication. During 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.
