Hello, hope someone can steer me in the right direction.
Replacing the ball bearings in a Star linear carriage, 4 units altogether. balls are 4.8mm/- 3/16; have no problem finding the size but how far up the quality ladder do I go? and can I use SS instead of the steel ones presently? Do they need to be a certain hardness?
As you might see in the second pic the difference in the balls, some where stuck in the back tube; had to drive them out with a drift punch, might as well change all the balls in all the bearing while I'm at it.
Thanks for any help you might have!! Cheers.
