What is the difference between 608ZZ and 608rs bearings?
What does a skateboard bearing do?
Skate bearings are the small circular devices that allow your wheels to roll, and will determine how fast and smoothly they rotate. ... A skateboard requires a set of 8 bearings, 2 for each wheel. Almost every skateboard bearing is the same size and will fit on any skateboard wheel and truck.
What is the difference between 608Z and 608ZZ bearings?
608z is single shielded and 608zz is double shielded. Same bearing other than that.
What size is a 608Z bearing?
Bore Diameter 8 mm
---------------- ---------------
Outside Diameter 22 mm
Closure Type Single Shielded
Overall Width 7 mm
ABEC includes five tolerances classes: 1, 3, 5, 7, and 9 with 1 being the widest and 9 the tightest. Thus, bearings with a higher ABEC rating have tighter tolerances, and that means better precision, higher efficiency, and the potential to accommodate applications requiring high speeds.Aug 24, 2015
What are the fastest ball bearings?
The Bones Swiss 608 Skate Bearings have become legendary since their introduction in 1983. For decades, this has been perhaps the fastest, smoothest and longest lasting bearing on the market.
Is ABEC 7 or 5 better?
ABEC 5 bearings are cheaper than ABEC 7. ABEC 5 bearings allow for lesser friction while ABEC 7 bearings almost give the skater a 'frictionless' cruise. ABEC 7 bearings are manufactured with stricter tolerance and are more precise than ABEC 5 bearings.
