What is the maximum diameter size pipe this can roll on. Thank you.

The groove fits a 7/16" rod at maximum (I'm guessing the groove has a 12mm diameter). Once you're at 1/2" the rod won't sit all the way into the groove.

What are the ratings for this bearing? i'm looking for static and dynamic load ratings, as well as the rpm rating.

Well made with approximately 1/2" diameter convex surface, don't know the ratings but good quality suggest 500# max load and could handle high rpm with the tolerances used.

i see that the bearing is made of stainless steel how about the roller?

Both of Pulley Bearings and roller are made of stainless steel Model is U22 Diameter is Approx. 22.5mm / 0.9in Hole Inner Diameter Approx. 8mm / 0.3in Width Approx. 14.5mm / 0.6in Material is Stainless Bearing Steel AISI440 (9Cr18) Package List incude 1 * Bearing

is there a larger version of this product that would accommodate a groove diameter of 26mm?

Dear Customer, Please check B08T1WR615 to see if it fits your needs, it has a groove diameter of 25mm. Best wishes,
