[DeTomaso] Upright Bearings ?

[B Hower]

I got my new press assembled and removed the axle etc. yesterday. And I had fun. In checking my bearing #'s I find the inside bearing has no # at all. The axle is under cut. And my outer bearing # is 6308-2RS1/C3HT51 which they tell  is (HT) high temperature.
My question is would the HT be better for our application? I understand that the 5208-2RSC3 is also available in the HT.
