Sector 9 Push Don't Pollute Bearing Set ABEC 5

Push, don't pollute!

These Sector 9 skateboard PDP Bearings are designed for all types of wheels! They come with two shields per bearing, thus allowing them to stay that much cleaner.

These currently feature a nice gray shield. Not much else is to be said about bearings. Just shred them and keep them out of water!

Sick Facts:

• Set of 8
• ABEC 5*
• Double shield for cleaner bearings between cleanings
• Spacers not included

*The ABEC scale is essentially a measurement of bearing tolerance for high precision bearings as dictated by the Annular Bearing Engineering Committee (ABEC). The scale runs from ABEC 1 through ABEC 9 using odd integers only. Essentially, the higher up on the scale a bearing is rated the tighter the tolerance is.

Tighter bearing tolerance means that the bearing moves with less resistance at high speeds, giving you a bit more roll for your push. In general most ABEC 3 or ABEC 5 bearings have steel races (shell of the bearing) with hardened steel ball bearings, and most ABEC 7 or ABEC 9 bearings feature steel races with super hard (much harder than steel) ceramic or titanium bearings.
