Are ABEC 1 bearings fast?
ABEC 1 is the most crude, the least precise, the most durable, and the cheapest. ABEC 3 is what most cheap complete skateboards come with, especially skateboards from China. ABEC 3 bearings work for most skateboarding, but won’t roll very smoothly or fast. ABEC 5 bearings are the norm in skateboarding.
What is an ABEC 1 bearing?
For an ABEC 1 (lowest grade) bearing, the maximum eccentricity allowable is 0.0075 mm (0.000295″). This is quite precise – more than precise enough for longboards and skateboards. The figures for the other ABEC grades are: ABEC 3: 0.005 mm (0.000197″)
What size are ABEC 1 bearings?
Ball Bearings ABEC Standard Tolerances Data

Does ABEC 11 exist?
ABEC from a precision standpoint refers to the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). ABEC precision levels do indeed stop at level 9 (there is no ABEC 11 precision level).
How is ABEC rating calculated?
The ABEC rating system uses odd numbers—1, 3, 5, 7, 9—as classification ratings. The five distinct classifications are arranged in ascending order of tolerance. A higher rating signifies tighter tolerances higher precision, efficiency, and speed capabilities for the bearing.
Are speed rings necessary?
Speed Rings are an often overlooked part of your skateboard, but not having them could be greatly jeopardizing your performance! Speed rings go on the outside of your bearings to give more clearance, allowing an uninhibited continuous roll.
What is a 608 bearing?
The standard inline skates bearings have the designation “608”. 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).
What is the ABEC classification for bearings?
It is an industry accepted standard developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). There are five (5) ABEC classifications 1, 3, 5, 7, and 9; the higher the number, the more precise the bearing.
What is an ABEC rating?
ABEC ratings have become the accepted industry standard for all ball and roller bearing tolerances, and as such, bearing manufacturers worldwide are required to have their products rated by ABEC. Once assessed, the rating is etched onto the bearing. Bearing tolerances are also regulated by equivalent ISO 492 and JIS B 1514 standards.
Are ABEC 3 bearings good for skateboarding?
ABEC 3 bearings work for most skateboarding, but won’t roll very smoothly or fast. ABEC 5 bearings are the norm in skateboarding. You get a reasonable amount of speed, and at a reasonable cost.
What is the tolerance level of a bearing?
The tolerance level of a bearing is referred to as an ABEC rating ABEC ratings have become the accepted industry standard for all ball and roller bearing tolerances, and as such, bearing manufacturers worldwide are required to have their products rated by ABEC. Once assessed, the rating is etched onto the bearing.
