https://www.google.com.au/webhp?sour...q=12x32x4+seal

and there is an 8mm deep bearing 620108 12x32x8mm

the one im using is a 6201 machined down to 6.6mm deep and the seal is a 12x32x7 but i sanded it down to 6mm wide.

in my 700 i use a slightly smaller bearing than the oem one inside a sleeve with a 5mm wide seal

or as mentioned already ORANGEBERG has a ready made kit for the job.
