Bearing Steel Sleeve is a wearresistant bushing designed to serve as a bearing sleeve in rotating assemblies. Made from bearing steel, it offers durable wear resistance for long service life and reduced maintenance. Key specifications - Inner diameters (bore): 14, 15, 16, 17, 18 mm - Outer diameters (housing bore): 20, 21, 22, 24 mm - Lengths: 12, 13 mm - Size: 18x22x20 (ID 18 mm, OD 22 mm, length 20 mm) - Material: bearing steel - Function: wear resistance for rotating shafts and housings Compatibility and use - Fits shafts with bore diameters 14–18 mm and housings with bore diameters 20–24 mm - Short lengths suitable for shallow housings and compact assemblies Practical use scenarios - Replacing worn bushings in small to medium duty conveyors or fans where a robust steel sleeve reduces shaft wear - In gearboxes or motors where a durable bearing sleeve maintains shaft alignment and supports rotating components - In automation equipment or CNC machinery where compact bushings are needed to fit limited installation space while providing reliable wear life How to choose and install - Select by inner diameter to match the shaft, then confirm the outer diameter fits the housing bore - Choose length to suit the installation depth; available lengths are 12 and 13 mm, with a standard overall size of 18x22x20 This description preserves the original specifications and function while presenting clear, actionable information for installation and compatibility.
