> 24 hourI tested all 20. There are no issues. These roll smoothly, and the machining is nice. I can find no play in them at all, and yet they are tight with minimal rolling resistance. I will be purchasing these again when needed. Big 5 star. Thanks.

> 24 hourWorks good for the price but they came with thick grease or something smeared inside. They dont spin good because of it until you oil them good then they are ok for the price

> 24 hourVery fragile bearings, they do not run smooth and can feel them grabbing when they turn. most were off-centered (see attached picture) and some had a lip in the bore, preventing a 3mm shaft from going through. These are good if you want to piss someone off and see their project fail.

Deep Groove Ball Bearings
- Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions (Mainly bear radial load, but also can bear a certain amount of axial load).
- With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
- Suitable for all kinds of industrial equipment, motor, roller wheels, office equipment and so on.
- Note: Please confirm the size and type of ball bearing before ordering.
Selecting Guide:
- Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
- Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
- Single-row
- Pre-lubricated
- Normal accuracy
