Excellent Performance!

As my tests showed, these bearings offer exceptional durability and reliability. They are well-suited for high-speed machinery and provide smooth operation even under heavy loads. The shielded design also helps to protect against wear and tear from contaminants.

Pros
  • Durable, reliable, smooth operation, shielded design.
Cons
  • Limited size range.

Work to improve the bogies of Lego wagons

I used them to create more realistic carts for freight and passenger cars (trucks). They roll better than standard Lego wheel holders. Fits into a technical pinhole with a little more effort.

Pros
  • They mainly carry radial loads as well as moderate axial loads.
Cons
  • Expensive

MR52ZZ (ID 2mm) Great Little Bearing. Hard Tolerances. The inner diameter is a little less than 2 mm. Rusted by moisture.

I bought these for an RC boat project to use on the driveshaft output. They are not rustproof and will rust after the first use. They continued to work after removing the rust so this is not a problem for me. Next time I will buy stainless steel. Rotated up to 25,000 rpm without noise and vibration. Amazing little camp.

Pros
  • Features: simple configuration, high speed, lower coefficient of friction, less vibration and noise.
Cons
  • Not sure
