Incredible Replacement Bearings

These bearings are amazing! They are incredibly durable and precise, making them perfect for any industrial and scientific environment. The chromium construction ensures long-lasting performance and consistent functionality. The only downside is that they can be a bit pricey, but the quality definitely justifies the cost. I highly recommend these replacement bearings for any power transmission product in need of a reliable upgrade.

Pros
  • Hassle-free replacement.
Cons
  • Expensive compared to other replacements.

Coated in motor oil or God knows what.

Although they correspond to the description and function, they are coated with engine oil or similar. This isn't the best idea for an accessory to a child's toy, and OEM balls don't come in this form. Not sure if it's toxic to my 6 year old so they need to be washed it's generally a bad idea to cover them that way. They appear to have been repurposed to fit the description but were not made specifically for Gravitrax.

Pros
  • Power transmission products
Cons
  • Small parts
