Hygienic Lead Screws and Nuts for the Medical Industry

Application StoriesMedical Industry OverviewBrowse the Lead Screw Shop

Lead screw assemblies used in medical lab equipment need to meet strict performance and hygienic requirements. Most metallic lead screws and nuts require lubricating grease to be regularly applied, making them unsuitable for such applications. dryspin® lead screw assemblies, on the other hand, have built-in solid lubricants that allow for consistent, reliable operation without the need for grease or other external lubricants that can cause contamination.

dryspin lead screw assemblies are also vibration damping, which reduces noise during operation and ultimately improves patient comfort, especially in console adjustments and other patient-facing medical furniture & equipment.

Our lead screw configurator is available to help customize and request a quote for your lead screw assembly in 20 minutes or less, and offers accurate service life estimates based on application requirements. A number of different lead screw nut materials are available, including FDA-compliant materials. We can even 3D print custom lead screw nuts with our wear-resistant printing materials for applications requiring more specialized components.

    • Visual Field Perimeter

    To develop a perimeter device for measuring visual field sensitivity, the application required a compact, hygienic, and maintenance-free solution suitable for medical environments. igus® met these needs with drylin® N flat guides and dryspin® trapezoidal lead screws with matching nuts, providing a 100% self-lubricating system. This ensures smooth, reliable motion without the need for maintenance, while also preventing dust and dirt accumulation—making the device ideal for hygienic, long-term use.

    • Filling Plant in Lab

    A fully automatic IVD filling plant that eliminates the use of grease and external lubricants to operate under cleanroom conditions. To fulfill the need for cleanroom suitability, dry-running operation, precision, and low weight, igus® supplied a trapezoidal lead screw nut made of iglide® L280, a trapezoidal lead screw made of AISI 304 stainless steel, and drylin® miniature guides. The result is a fast-available, maintenance-free solution that ensures precise motion in clean environments without lubrication.
