Standard bearings in four sizes for compact mechanical assemblies. Models 32203, 32204, 32205 and 32206 provide defined inner diameters (ID), outer diameters (OD) and thickness/height (TH) to fit a range of applications. The dimensions are as follows: Model 32203: ID 17 mm, OD 42 mm, TH 12 mm Model 32204: ID 20 mm, OD 47 mm, TH 19.25 mm Model 32205: ID 25 mm, OD 52 mm, TH 19.25 mm Model 32206: ID 30 mm, OD 62 mm, TH 21.25 mm Key benefits Clear, standardized bore sizes: enabling precise fit with compatible shafts and housings for reliable rotation. Four size options in the same product family: helps you select the exact bore, outer diameter and height needed for your design or replacement. Consistent dimensions across the model range: supports straightforward replacement and predictable performance in compatible assemblies. Compact form factors: suitable for small to midsize equipment where space and weight are considerations. Applications and use scenarios Replacing bearings in small household appliances, hobby robotics, or model engineering projects where the listed IDs, ODs and heights match your design. Integrating into compact drive systems, including hobby CNC machines, 3D printers, and robotics modules requiring precise bore and overall dimensions. Maintenance and upgrade of existing equipment that uses standard 32203–32206 bearings, providing a straightforward upgrade path with a consistent size family. How to choose and install Select the model that matches your required inner diameter (ID), outer diameter (OD) and thickness/height (TH). Verify compatibility with your shaft and housing to ensure a proper fit. If replacing an existing bearing, confirm the replacement bore sizes and overall dimensions align with the original parts to avoid installation issues.
