Which abec

The ABEC rating system has been around for the last 35 years. However, since every bearing is used in a different manner and environment, bearings should be redesigned or "customized" for special uses like skating. The ABEC rating system is not intended to be the only criteria used for selecting bearings for use in specialized applications like skating. It is only one of the tools a bearing designer can use if it is appropriate for the application.

The ABEC rating system includes grades 1,3,5,7, and 9. The higher the ABEC rating, the tighter the tolerances are, making the bearing a more precision part. Nylon cages may have some slight advantages over steel cages in that it could possibly help to dampen the shock loads associated with skating, and it may assist in holding the lubricant in. Honestly though, we'd be suprised if you can tell the difference!

One big advantage of a nylon cage over a steel cage is that nylon cages are easy to remove - so you can completely strip the bearing for a full clean. Steel cages are basically impossible to remove, so you wont be able to dissaemble the bearing and you'll be stuck with a half-arsed cleaning job. Decks Expand menu Collapse menu.

What do "Z" and "ZZ" mean on a bearing? What does "RS" mean on a skate bearing? What does "2RU" mean for skate bearings? How to get more speed from your bearings. If you really want the lowdown on exactly what the ABEC rating means, read on ABEC rating - What does it mean?

What are the grades of bearings available in order, and different are they? Is there a lower grade than ABEC 1? Are there any other standards for measuring Bearing precision? What is the purpose of the higher precision bearings, as attained by the ABEC standard? You will need to use some type of shock absorber that allows for absolutely no vibration.

Doing so would cause shock loads to the bearings and any extra precision would be lost very quickly. We have to believe that they are until it is proven otherwise. What is the meaning of "Z" and "ZZ" in the bearing code? EG "ZZ" "Z" is a designation which means a steel shield covering the side of the bearing for most brands. What does "RS" stand for on a skate bearing? What does "RU" or "2RU" stand for on a skate bearing?

What does "" mean for skate bearings? For those who need to know, the dimensions of a standard skateboard bearing are: Inner Diameter 8mm Outer Diameter 22mm Width 7mm back to top.

Customer Login. We are often asked, "What ABEC rating are the best for scooter , skateboard or roller skate wheel bearings? Similarly, contrary to popular belief, the ABEC rating does not affect speed! This is a common misconception made by many people. This is the main reason for the price increase, the higher the rating, the higher the cost to produce the bearing. In the case of wheel bearings, these ratings do not necessarily affect speed.

If speed is your primary concern however, then our advice is that you should go for well lubricated bearings, or not as the case may be dependent on your skating or riding style. The ABEC rating system has been around for the last 35 years. However, since every bearing is used in a different manner and environment, bearings should be redesigned or "customized" for special uses like skating or scootering.

The ABEC rating system is not intended to be the only criteria used for selecting bearings for use in specialized applications like skating. It is only one of the tools a bearing designer can use if it is appropriate for the application. The ABEC rating system includes grades 1,3,5,7, and 9.

Most of what the skateboarding public knows about the ABEC rating of bearings is based on some sort of folklore. Oddly enough, the primary selling point for bearings, aside from price and pretty packaging, is their ABEC rating.

The precision bearing has been a vital component of skateboarding since when Road Rider wheels hit the streets with the first known precision bearing for skateboards. The bearings used for those wheels were originally manufactured for use in vacuum cleaners, and had an ABEC 1 rating. The duty of the ABEC committee is to establish tolerances and specifications for the size and geometric accuracy of all bearings.

Bearing manufacturers from all over the world send their bearings to the U. Once rated, companies etch the rating onto the bearing. The ABEC rating system uses odd numbers, ranging from 1 to 9. The higher the number, the tighter the tolerance of the bearing, and thus, the greater degree of precision.
