Question by: Merle J on Dec 21, 2025, 7:52 PM

roller bearing gear pump, what’s the real advantage there over a sleeve bearing one?

Answer by: Customer Support on Dec 23, 2025, 3:57 PM

Roller bearings cut down internal wear compared to sleeve bearing designs, which helps the pump hold up better over the long haul. That setup is aimed at extended service life when the pump is kept under continuous load in demanding industrial work.

Question by: Dean M on Oct 20, 2025, 7:56 PM

Been running sleeve bearing pumps for years and always had trouble with wear. Does the roller bearing setup on this Permco actually hold up better over time, or is that just sales talk?

Answer by: Customer Support on Oct 22, 2025, 6:50 AM

Roller bearings genuinely do reduce internal wear compared to sleeve bearing designs, and that holds true here. The construction on this pump is specifically built around that advantage, which translates to longer service life under continuous load. For applications where the pump is working hard day in and day out, that difference tends to show up over time in how the unit holds up rather than just in spec sheets.
