The XSM-4044-40 is a 40mm long, 40mm wide, and 44mm high aluminum anodized linear slide from Igus. This slide is part of their xiros series, and is equipped with self-lubricating plastic glide elements, which make it up to 86% lighter than ball-based linear slides, and also suitable for dry-running applications. The slide also has a protective anodized finish for environmental protection, as well as a stainless steel, corrosion-resistant cage. It also has a dynamic load rating of 100N (maximum of 200N), and a static load rating of up to 250N. For easy servo integration, this slide can be mounted in two directions, using two 8mm tapped holes.
