Pillow Blocks (Housing)
Some users buy housings or bearings separately and some customers buy a complete set of bearings and housings. All selections are decided on the actual using requirement. It's some difficult for us to assemble bearings and housing by ourselves. It needs to fix the housing first and put the bearing into the hole of the housing. And then push the bearings into the housing with a crowbar use of the principle of leverage. Don't try to assemble if you don't have experience.
