Best Angular Contact Bearings
Its precision. is rated at ABEC 1 by the Annular Bearings Engineers Committee (ABEC), allowing higher speeds and creating lower friction than less-precise ball bearings, and its radial internal clearance is C3 for radial slack between the inner and outer rings. is greater than CN (normal) to compensate for thermal expansion. Removable single lip contact seals on both sides to protect against contaminants and retain lubrication.

"The quality and function varied wildly within the batch; some of the stamped steel bearing cages were deformed to the point of being almost completely locked up."
"I got them to put in some fidget spinners and to play around and craft my own fidgets."
"For the price these are perfect... Not of the highest quality, but function fine for silly low load stuff."
"The bearings are sturdy and came in a value pack of 100 in case we need to replace any and if we get another skateboard for my daughter."
"Light coat of oil here and there but no evidence of intentional lubrication inside."
"The bearings are probably made for very heavy machine loads, because the ball cage is metal and double sides."
It supports radial loads, thrust loads in both directions, and combined loads, and occupies less thrust space than a pair of single-row angular contact ball bearings mounted together. The 20-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a standard contact angle of zero degrees. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use.
