I bought the NSK 7007AW bearing which is detailed here: https://en-mx.misumi-ec.com/vona2/de...ssuCode=7007AW
But I now also see a lot of people are using the 7007B instead: https://uk.misumi-ec.com/vona2/detail/221000058233/?HissuCode=7007B
The main differences are the Retainer/Holder type. The B is a momi removing and the AW is a punching. The other main difference is the contact angle, which on the B is 40 degrees and 30 degrees on the AW.
Do these differences matter, or can we just use the bearings we already bought (the AW)?

Re: G0704 AW Vs. B Series Spindle Bearings
They have the same load rating, so I can't see any reason not to try it.
