What does ABEC mean on bearings?
Annular Bearing Engineers Committee
The purpose of the ABEC committee (Annular Bearing Engineers Committee) is not to test every manufacturer’s bearings and proclaim them good or bad, but to establish dimensions, tolerances, geometry, and noise standards for bearings in an attempt to aid industrial bearing manufacturers and users in the production.
What is the difference between ABEC 5 and 9?
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.
Are ABEC 3 bearings fast?
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. ABEC 7 bearings would be very fast and smooth, but very expensive.
What are ceramic bearings?
Ceramic bearings are comprised of ceramic rolling elements (balls) enclosed in a ferrous (typically steel) inner and outer race. Since these bearings are constructed from many materials, they often operate in hybrid capacities.
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 does ABEC mean?
ABEC stands for Annular Bearing Engineers’ Committee and is the U.S. method for rating the accuracy and tolerance of bearings. ABEC standards are set by the American Bearing Manufacturers Association. Bearings are used for all kinds of things, not just skateboard wheels.
What is the best ABEC bearing for skateboarding?
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.
What does ABEC rating mean on skateboard wheels?
Bearings are used for all kinds of things, not just skateboard wheels. The higher an ABEC rating, the more accurate and precise the bearing is. When companies make bearings, sometimes they cheaply slap them together, and sometimes they very carefully design and assemble them with as little space as possible between the parts.
