Ccould someone remind me what bearings (dimensions) go into lower part
of a Bridgeport spindle?


Pretty sure on the r8 spindle it is 2MM207* in Fafnir

Industry std nomenclature would be 7207* followed by a letter to designate
contact angle, probably B or C

In Barden it would just be 207

SNFA has a ******* numbering system IIRC so you'd have to look it up using
the boundry dimenions.

Here's a nice bearing manual in .pdf
