Jib crane bearing races

1 Attachment(s)

Sometimes it is next to impossible to find the size bearings you need so you have to make them
Shown below is a 28 inch diameter bearing set for a jib crane
the way the races are machined the inner race fits around a H beam and has a 90°contact area for the balls
the outer race still in the lathe has a 90° contact area as well but is the opposite of the inside this way the bearing was not only 100% thrust capable but 100% radial as well Not like the angular contact bearings that can be bought off the shelf
the material was ASTM 514 T1 steel later it was surface hardened.

Horizontal Bead roller set up

Once I needed to make a turn table to be mounted in the floor for rail mounted trolleys to traverse and change directions. To do this I wanted a rubber seal to keep out dirt or water when the floor was cleaned
I mounted my bead roller on the turn table then made the bead in the metal ring tacked to the turntable
