While vacpress design look nice and makes it feel like it would be easy there are lots of dificulties on actualy making them, the precision is on of them. Also the small problem of a late, archiving exact same dimentions on all linear bearings, hadren the steel. It is way cheaper to buy a precision machined linear guides/bearings than making it oneself (speaking for regular people).
Beny you cannot use radial bearings with axial loads, they will wear way too fast. I didnt knew that bearings are so darn complex until I read a document describing a spingle design, so many variables to consider, the axial and radial loads, speeds, lubrication, temperature. |
