The basic info of skateboard bearing is your should know what is skateboard bearing. Skateboard bearings inside the wheels enable your board to roll. A standard skateboard has eight bearings. A plastic or metal ball retainer covers the bearings to protect from dirt and moisture.
The standard sizes for skateboard bearings are 608 skateboard bearings. The "608" means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore). The "6" appears to be for the 6mm difference between the inner and outer radii (from the outside edge to the edge of the hole). If your bearings have letters following the "608" (like "S", "Z", or even "ZZ" or "SS") it is the manufacturer's way of denoting sealed or perhaps double shielded bearings. An "RS" label means shielded but that the shields are removeable (i.e., serviceable bearings). To make sure what they mean you should probably check with the manufacturer, since it can vary from company to company.
If you do not have a good idea of skateboard bearings info, when you choose those bearings you may choose brand one first. There are many brands of bearings out on the market now and also with many material such Stainless Steel Bearings, although you should know that some are just bearings from the same factory, just labeled differently. Some brands are NMB, Powell Swiss (commonly called Bones bearings), GMN, Fafnirs, Black-Hole, YAKs, Twin-cam, M&A Smith Stealth, (Super) Sonic, Terminator, Hyper (Boss & RPM), FKD, NHBB, GMBH, DF, Grizzly. No matter the brand, the skateboard bearing which suitable to your skateboard is the best. Do not need to chase brand.
In fact, from this skateboard market we could see, some famous brand focus on high precision and High Speed Bearings they could offer. In fact, high precision and small tolerances are required for bearings to function at very high RPM (Revolutions per Minute), that must spin at 20,000 to 30,000 RPM. At that speed, an ABEC - 7 or 9 bearing rating may be appropriate. However, a skateboard with 54mm wheels turning 20,000 RPM will be traveling about 127 MPH! Since most skating is done under 30 MPH, the realistic maximum RPM your skate bearings will see is about 4700 RPM and probably 90% of skating occurs under 2000 RPM. So, very high precision is not required at skating speeds.
Remember especially you do not know skateboard bearings info, do not overpay and chase brand, high precision, high speed and so on. First you should realize which one is most suitable to yourself, then decide which kinds may you be able to handle well, at last just go for skating.
