Review on Akozon Groove Bearing U624ZZ Pulley by Justin Olson

Revainrating 2 out of 5

Poor quality assurance

Either I was unlucky or this manufacturer doesn't have a quality assurance department, to be honest I only bought a 10 pack. The holes in some of these bearings are off center and it shows. 4 out of 10 had a wobble that rendered them unusable.

Pros
  • Long term use
Cons
  • Expensive
