After mock-up and measuring, the mounting points for the pillowblock bearings were drilled out in steps. We went through quite a few bits doing so. We will be using 2″ bearings to hold the roller for our dyno. For more info check out the progress at our website: cot-wiki.tech.uh.edu
Free running of bearing diminishes as the pressed steel housing is tightened

Into DIY types of projects; it should go without saying that having the finest in safety equipment or equipment in general is a must. This is especially true for those jobs that have a lot to do with holding up foundations. That’s why when choosing a pillow block bearing, or housing bearing as their also called, get the best that are available; and if the best aren’t available, hold off on the job. For something as dangerous as the pillow block bearing, having it be in anything less than the best condition is ill advised.
The way a pillow block bearing works is by having a flat surface on the bottom of a ring. The ring supports any beams that might rotate, while not letting the entire contraption move at all; that way if a paling needs to move, there won’t be any damage to the building by the whole system moving.
Pillow block bearings are indeed used for the foundations in many things. Buildings, homes, schools, if they aren’t properly installed, or start to have trouble, that could mean a whole building collapsing without a thing to be done; except pray no one is hurt and build the place back. There are just some things in life that cannot be bought at the ‘bargain bin’, and pillow block bearings are well and truly in the category of splurge. But it’s not just about getting the most expensive brand; one also needs to know the overall quality and durability of the product. It’s apparent that the only way one would know the true quality of one is if it stopped working, but that’s not something anyone wants to happen; hiring a good contractor will go a long way.
When hiring someone to lay down foundation for a building, they are going to have to use a pillow block bearing at some point; therefore, conferring with them on what the best method and type to use would be better in the long haul. Now that’s also why picking a good contractor is very important in more than one way. If they don’t know exactly what they are doing, a collapsed building might go from a nightmare to a reality. Check, check, and check again with references, previous jobs, and overall education. Even these aren’t fail safes against poor contractors, but at the very least it’ll lessen the chance of getting a bad one.
