Good for roller bearings

- Runs very smoothly without additional lubrication; Size description is correct. I placed it in a drilled slot in a block of wood to use as extra support for a rotating stainless steel motor shaft extension that drives a 4 1/2" circular saw blade.

Pros
  • High carbon chrome steel rollers, through hardened for heat resistance and durability under heavy loads
Cons
  • Wrinkled
