Reliable and Durable Flanged Bearings

According to my experience these double shielded flanged bearings are highly reliable and durable .They have smooth operation and provide excellent support for my printer. The zinc-coated flanges also protect against corrosion, making them ideal for long-term use. However, they are slightly more expensive than other bearings on the market, but the quality is worth the price. Overall, I highly recommend these bearings for anyone in need of a dependable and sturdy option..

Pros
  • Effective at reducing friction and maintaining stability during printer operation.
Cons
  • The small size may limit compatibility with certain printer models.

The good are good.

Unfortunately I only received 8 bearings in the package. In the photo you can see that the three on the right appear to have some sand straight out of the box.

Pros
  • 4x9x4 mm
Cons
  • No instructions
