Flanged housings of smaller sizes are triangular and the larger sizes have a square shape. They can be used for self-aligning ball bearings and spherical roller bearings. They can be used for tapered bores on an adapter sleeve on smooth shafts.
Flanged ball bearings require felt seals and grease lubrication. They are made of gray cast iron. Different types of flanged ball bearings are used for mild and harsh conditions.
