Perfect for my motor project
These bearings fit exactly as specified. Smooth rotation and minimal play. Great for high-speed applications.

Good quality
Solid construction. One bearing was slightly stiff initially but loosened up after use. Good value.

Standard precision
Not ABEC-7 but for the price, these are excellent. Good for general machinery use.

Reliable import
Exactly what I needed for my CNC spindle. The flanged design makes installation easy.

Smooth operation
Very quiet under load. The ZZ shields keep dust out effectively. Will buy again.
Q: What is the maximum RPM?
A: Depends on load and lubrication, but generally rated up to 30,000 RPM for smaller sizes.
Q: Are these suitable for water exposure?
A: These are metal shielded, not rubber sealed. We recommend avoiding direct water exposure.

A: This listing is for a pack of 10 to ensure safe shipping and value.
Q: What are the exact dimensions for F618ZZ?
A: Please refer to the specific size chart in the images. F618ZZ is typically 8x16x5mm.
