"Fantastic Performance, Compact Size.

"I used these bearings in a DIY project and they exceeded my expectations in terms of smoothness and durability. My analysis of this product showed that they are easy to install and require minimal maintenance. The compact size is a plus, making them ideal for small scale projects. The only con I can think of is the price, but the quality makes it worth it..

Pros
  • Smoothness, durability, easy installation, compact size.
Cons
  • Price.

Correct size, normal twist

These fit 4-12-4mm but have quite a high resistance for their size. The friction between the bearings and the inner/outer layers is too much to rotate freely. It can still rotate with an applied force, but it will stop rotating immediately if no force is applied to it, meaning internal friction will stop it.

Pros
  • Power transmission products
Cons
  • Something different
