Pillow block question

[rasorbackq]

What is the difference between a standard duty and a medium duty? Princess Auto now sells a med ium duty block . Searched the net for the answer but only catalogs sales appear.

Likely different load ratings. Did you check the specs?

Probably the difference is the number of balls inside the ball bearing.

What's in a name?
Lacking a spec sheet showing a greater load capacity, it sounds like pure marketing hype to me.

I found only a difference between standard and heavy. It was the webbing, how the outside steel was constructed around the bearing. Thicker all the way around with larger "Fins" that meshed to the bolting tabs. The tabs were solid (Not hollow).
