Mini-Rail® Miniature Linear Guides consist of ceramic coated aluminum linear rails and anodized aluminum carriages, underlined with a self-lubricating FrelonGOLD® liner that produces a gliding surface along the rails (Gliding Surface Technology or GST). The guides require little maintenance and can withstand harsh and high temperature environments. The linear rails and carriages are dimensionally interchangeable with industry standard sizes, and are maintained in stock for quick delivery.
