Description

NOTE: Please refer to the picture and select right type of bearings before your order (Sealed or Shield on BOTH or SINGLE side of the bearing). Suffix on the bearing just for differentiating between Sealed and Shield type of bearing. It would not affect the use of our product. Description: 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. Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on. With small friction and high-limit speed, Uxcell's Deep Groove Ball Bearings are cost-effective and require little maintenance. Carbon Steel bearings are better in toughness than chrome steel bearings after quenching. These cost-effective bearings are widely used in areas with low requirements for Mohs hardness. Single-row, pre-lubricated, normal accuracy. Selection Guide: Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris. Sealed (Designation SuffixRS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings. Specification: Model: 693ZZ Shield Type: Double Shield Material: Carbon Steel Cage Material: Stamping Steel Inner Diameter (d): 3mm Outer Diameter (D): 8mm Thickness (B): 4mm Accuracy Class: P0 (ABEC-1) Number of Pack: 20 Pcs Weight: 18g

  • High quality
Size: 4mmx13mmx5mm
Used to remove friction heat from powder actuated machine that had pins in holes now holes are bearings

  • Quality as expected.
Size: 3mmx8mmx4mm
Exactly as described just wish the quantity per order could be adjusted when purchased. The bearings are excellent just more than needed.

  • Exactly Right
Size: 3mmx8mmx4mm
Working a project that needed exactly these.

  • Worked good
Size: 7mmx22mmx7mm
Normally I don't like ZZ seal bearings. I prefer RS so the seal can be taken out and grease added. For my project no additional grease was needed so these worked perfect.

  • Do Not Spin Well
Size: 3mmx10mmx4mm
Quality is terrible on the bearings. Also, some of them had a bigger inner diameter than others... Overall, super dissapointed in this product. Less than 20% of the bearings were usable. I would not recommend this brand for this size bearing.

  • Not as smooth as the old bearings were
Size: 3mmx8mmx4mm
These bearings (693ZZ (3*8*4)) were used to replace the bearings in a quadcopter motor. they seem louder that the other bearings. The ones that were being replace were damaged from a crash so these are an improvement over the damaged ones. Just spinning the blades by hand result in about 2 turns of the new bearings vs about 6 to 8 turns of the blades on the other motors. Perhaps these will "wear in" but the others did not need this activity. They seem strong and smooth but I think they may be a bit "tight" for a high speed quad motor. ... show more

  • Not accurate measurement
Size: 3mmx10mmx4mm
These bearing are advertise as 1/8" or 3mm ID. But what you get is 15/128" or 2.95mm which if you are using these for any rotary burr tools, it won't fit for just that small amount of precision. Picture shows that the burr tool's shank get stuck right after first 5 or 6 mm and won't go further. If the ID is as advertised at 3mm, it would have been a perfect fit. ... show more
