Typically for the aftermarket parts this is an NSK part inside the Gates or Beck/Arnley box, and often the same as the OEM, but parts from aftermarket suppliers vary. We try to only source quality Japanese Koyo, NSK, or similar bearings and avoid Chinese made parts whenever possible.
This can be used on the Gen 2 and Gen 3 3SGTE engine to also replace the pulley/bearing on the upper swinging tensioner bracket without replacing the entire bracket.
