💡 What is a roller follower used for in linear motion systems? It guides rolling contact and absorbs radial load in cam and track applications. - Ideal for cam follower, conveyor, and linear slide unit setups needing sealed ball bearing-style performance. - Offers high radial load capacity, reduced friction, and compact mounting for indexers and guides. - Caged separable designs are handy for installation, inspection, and relubrication through an oil port.
