Drawn cup needle roller bearing with a closed end for shaft end applications with high dynamic loads. Drawn steel outer shell (cup) has a reduced cross-section for use in restricted spaces. Full complement of rollers for greater load capacity than caged bearings. Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads. Meets standards ANSI/ABMA 18.2 and ASTM F2162 for quality assurance.

Works well, I hope they last as long as the vintage.

Well they are bearings and they are made by Koyo what else can I say? Ordered to replace the kit on a manual punch press at an old ladies elementary school. They worked well, I hope they last as long as the old ones (10-15 years).

Pros
  • Certified
Cons
  • Cable is shorter than other picks
