I am trying to obtain a pillow block housing for a tapered roller bearing with a 62mm outer diameter. Normally, for a spherical bearing, this would be a type P206 housing. The outer race of a tapered roller bearing, however, is cylindrical, not spherical, so it will not go in to a P206 housing. I called a bearing supplier and they said that all pillow block housings are spherical (have a curved inside) and that cylindrical pillow block housings do not exist. He said we would have to machine a customized housing ourselves. Is this true?
