Waste of Money for my opinion

This product is not worth the investment! The bearings did not last very long and I had to replace them sooner than expected. The only pro— they are cheap. The cons include low quality, and not suitable for long-term use. As someone who works in the Industrial and Scientific field, I highly suggest investing a bit more for a better quality bearing. Don't waste your money on this product.

Pros
  • Long-lasting and durable
Cons
  • May require lubrication before use

Worked in my Kubota Kommander

Ordered them to try and one bearing broke right out of the box, feels very gritty and catchy. I have used others to replace the bearings in my Kubota Z125S idler and idler pulley. We'll see how they hold up, but I'm not sure they'll last very long as there doesn't seem to be any quality control. Hopefully they'll last a season and certainly better than paying $40 in Kubota for new pulleys with bearings.

Pros
  • Deep groove ball bearing
Cons
  • Questionable buy for seniors

Spare part for Sunny SF-B1877

This replaced two completely destroyed rear crank bearings on a Sunny Spin Bike model SF-B1877. This is the same "model number" as the warranty parts. They were easy to install and worked great. Not sure about durability as I just replaced them. I'm glad they came in a pack of four though. It should be noted that if you're swapping out bearings on a spin bike, you'll need two of the four, not one, so keep that in mind.

Pros
  • Ball bearing
Cons
  • Very expensive
