Bearing help Please

[rodzilla]

Could someone tell me if a 6201 bearing would work instead of using 7201 Angular contact Bearings as i have access to free 6201's they are 12 mm I.D. and 32 mm O.D. the sides of the bearings are sealed my question is would they hold up to the load placed by the machine table

wouldn't a thrust bearing work better for this application do to the direction of force on the bearing axial vs. radial

Not enough information. Are these bearings to be used for ballscrew/leadscrew support? If so, fixed or "floating" end? 6201's are radial bearings, little thrust cadacity and have end play or clearance. 7201's are angular contact of various angles, applied in pairs and are normally preloaded to eliminate end play.

Thrust only bearing will not give any radial support and will require a radial bearing as well. Thrust is in two directions, if my ASSumption for screw application is correct, will require bearings for both thrust directions.

Search for NC Cams many contributions to the Zone on this subject. In his past life he was and is a qualified bearing engineer.

Kinda depends on budget and expectations.
