💡 What is a roller follower used for in linear motion systems? A roller follower supports and transfers loads along a guide or cam surface, keeping motion smooth and precise. - Common uses include linear slide units, cam followers, indexing systems, and automation machinery - Compared to sealed ball bearings, needle roller followers offer a slimmer profile and higher radial load capacity - Materials range from high carbon chrome steel to ceramic rollers for specific corrosion or speed needs - Maintain with proper lubrication through the oil hole and choose non-separable types for simpler assembly
