Default Question on ACL Bearings

I am looking to get the ACL bearings, and noticed the part numbers that I see from various suppliers has an H at the end. When I went to the ACL website, they show an HX version that is only offered in standard sizes. I was always under the assumption that most race versions of bearings only come in standard size.

Also, the thrust bearings only come in one version, and they do not have the H at the end according to ACL. It is part # 1T8353

Has there been a change in the part number?

What is the biggest difference in th H and HX? I want to be sure to order the right parts, and prefer a true race bearing unless there is some very good reason not to.

Thank you.

Don't know the part numbers , H vs. HX, but the thrust bearings only come in the standard ( not race). The main and rod bearings come in both, get the race.

Of coarse, I went straight to the bottom looking for the part numbers and failed to observe the H, HX, HD, and HXD suffix descriptions on the second page of the catalog.

I will save you the trouble of looking it up. HX is simply 0.025mm (0.001") extra clearance. Other than that the construction is exactly the same.
