💡 What is a set-screw shaft sleeve used for in linear slide units and bearing housings? A set-screw shaft sleeve locks and supports a rotating shaft inside a housing without a press fit, keeping alignment under load and simplifying maintenance. Quick overview: - Shaft locking and alignment for linear slide unit applications. - Low-friction plastic sleeve reduces wear and pairs well with sealed ball bearing and ceramic hybrid bearings. - Narrow stainless collar lets you mount in tight machine hardware and conveyor systems. - Single-pack replacement option for maintenance, retrofits, and bearing housing upgrades.
