a question about differtent ABEC bearings.

[yo-bear]

what is the difference between an ABEC1 bearing,ABEC3,ABEC5,and ABEC7 bearings?

@Icthus

Abec is a rating that has absolutely nothing to do with yoyo’s.

I don’t want to type it so just read here.

To paraphrase the link icthus gave, the ABEC rating has to do with tolerances. How close to spec the inside and outside diameter are. That really isn’t important with yo-yos. The rotating accuracy of bearings is extremely important in a precision tool such as a lathe but doesn’t matter on a yo-yo.

at a shop they have abec7 bearings for 25$ dollars while the abec1 is like 6$.why is this.which is better for yoyos to increase spin time and needs to be lubed less often.

@kyo

As to the ABEC ratings question… the simplest explanation is that it’s a rating system based on series of tolerances that have no impact on yo-yo performance.

Alright, Mrcnja, I want to see if you can reply to this in a quoe. GO

how do you quote from other threads?

ABEC is the closeness to a precise size/shape the inner and outer rings of the bearing are.

The ABEC and ISO bearing standards are primarily concerned with bearing tolerances. While tolerance is an important factor in the performance of a bearing, there are many other factors that also affect the suitability of a bearing to its application.

ABEC and ISO standards do not cover: radial play, raceway curvature, surface finish, material, ball complement, number, size or precision level, retainer type, lubrication, torque, cleanliness at assembly, packaging and other factors that may be essential to the desired bearing performance.

Yo-yos spin at RPMs < 15,000, so the lowest grade (ABEC 1) is sufficient.

Higher ABEC doesn’t necessarily mean a better bearing for your yo-yo.

A high grade bearing would be used in something like a dental drill.

Don’t base your decision on a bearing on ABEC itself…  for the reasons I quoted from DynaRoll, there are many other important factors that ABEC has nothing to do with.

High grade bearings are rated to be able to handle higher RPMs and run smoother at higher speeds.

Higher ABEC itself won’t make your bearing spin faster.
Lighter (low viscosity)/less lubrication will.

Many sources (some dude’s website, skate website, random eBay article, forum posts) are laden with false information so…yeah.
