20 iron sleeves, height 95 mm Inner diameter options: 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72 mm Outer diameter options: 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 70, 82 mm Screw types: M10, M12, M14, M16 Key benefits Durable iron construction provides reliable strength and wear resistance in mechanical applications. Wide range of inner and outer diameters supports precise fit, enabling versatile use with many shaft and housing combinations. Standardized height (95 mm) helps ensure consistent assembly and alignment across sleeves. Compatibility with common screw sizes (M10, M12, M14, M16) facilitates straightforward mounting and integration. 23 use scenarios Replacing worn or damaged sleeves in machines or equipment that require varied inner diameters (34–72 mm) and corresponding outer diameters (44–82 mm) with M10–M16 screw compatibility. Used as interchangeable spacers and bushings in mechanical assemblies where shaft alignment and support are needed across multiple diameter specifications. Stock item for workshops and fabrication shops to support retrofits, repairs, or prototype builds that demand sleeves with specific inner/outer dimensions and standard screw connections.
