Need 3 5/8 closed end bearings.
Check okorder . They'll have what you need if you can navigate your way through their enormous on-line catalog to find it. You'll need a credit card to place an order. These folks must be the world's largest engineering supply company. You want pillow bearings for a 3 5/8 shaft? They won't be cheap. Why would anyone want a closed end linear bearing -- sounds like an oxymoron. Seems I have more questions than answers.
