Nice to know. "Includes a locking collar"...... some thoughts on that...

The eccentric collar will lock tight in both directions on the inner sleeve - BUT only one direction is correct - it MUST be locked in the direction of rotation.

If not locked properly, even in the correct direction, vibration will shake it loose.

It must be installed completly dry and free of any lubricant inside the collar / external surface of the bearing (these are usually sprayed with a rust preventative that must be removed).

For the first reason, these must not be used on reversing rotary applications.

You may install it properly, whoever services it next may not.

That collar is the only thing keeping the inner race from spinning on the shaft, the outer is captured stationary by the flanges.

 

Short version - these can cause too much grief - all remidied by the other version with the two setscrews.

Yeah,

these were used on the Job years ago, they do have a punch hole makes them recognizable.

I thought the locking collar is set in opposite direction of travel?

”I was all excited like a little girl getting a pony”, dang!

Thanks tho’, take care of it in the am

I stand corrected - but I still avoid thwm as well as designing anything with a #6-32 hole that needs to be tapped!!! About a 50% chance of snapping off the tap.

There’s some with set screws on eBay for 32.99 ea. I may try cancel part of my order and get these.

6-32, only very thin material!

I firmly believe that the #6-32 thread was invented by the same sick puppy that gave us the hair trigger and short fuse!!

Thought about what ri702bill said and I did get the better bearings ordered, not wanting any issues out of the ordinary!
