UC203 + FL204 and UC204 + FL204 use the same FL204 housing because both insert bearings have a 47 mm outside diameter. Their main difference is the bore size: 17 mm for UC203 and 20 mm for UC204. UC203 + FL203 uses a smaller housing, typically measuring 99 mm long with a 76.5 mm mounting-hole center distance, while FL204 is 113 mm long with a 90 mm center distance.
