180Pcs 608 Ball Bearing ABEC-5 8X22X7 mm Deep Groove Carbon Steel Sealed

For ball bearings, the radial internal clearance is C3, so that the radial slack between the inner ring and the outer ring is CN (normal) to compensate for thermal expansion. Heat treatment is performed to increase hardness to improve wear resistance.
It has deep ball grooves in both seat rings and can withstand high radial and axial loads; its straight holes can be fitted with traditional cylindrical shafts; the nylon cage prevents the balls from contacting each other during use, Which reduces friction, vibration and noise.
Removable single lip contact seals on both sides prevent contaminants from entering and maintain lubrication during manufacturing. The ball bearing is suitable for skateboard, inline skating and other roller skating applications.
