Bridgeport Angular Contact Bearings?

[79TigerPilot]

HI,
I have a similar issue to Pofo. I am trying to reduce the backlash on my X & Y axis. I am not exactly sure how to put the angular contact bearings back on. Both the bearings have an arrow etched on the outer race. Need to know which way I should point the arrows, at each other or away from each other.? I would think you wouldn't point them in the same direction, but I am just not sure.

Any one know how these should go.


Thanks,
Craig

Normally, the arrows on the bearings (known as chevrons) are different on each bearing. The two bearings when put together should form one continuous "arrow" exactly like the " > " symbol. They will only match up one way to form the symbol.

This may be of interest to those on the forum.

There is a seller on ebay right now that has those ultra quality ballscrew bearings that NcCams has written about many times. They are 20TAC47 DF P4 matched pairs and only $105 a pair!!! That is dirt cheap! I bought a couple pairs and they are beautiful.

Thought others here might want to jump on this deal.

The bearings have an actual arrow ===> etched in the race.

Well they have to mount one of two ways, either DF or DB. A quick google will show you the two methods. In either case, the two arrows will point either directly at each other or away. I would guess they point at each other in their intended mounting configuration (DB/DF).
