Skate Bearings - Question 10

What is the purpose of higher precision bearings?

Higher precision bearings are designed to allow high precision machinery to operate smoother and sometimes at higher speeds than a standard bearing would allow. Keeping this in mind, no matter how good your skates are, they are not classed as high precision machinery. A standard ABEC1 608ZZ has a limiting speed of 32,000 RPM with grease lubrication and 38,000 RPM with oil lubrication. The actual speed the bearing will attain without failure also depends on the loads applied and other running conditions but there is really no need to go into that too heavily here.

We feel that we must stress here that the purpose of higher precision bearings is not to go faster, but amongst other things, to allow high precision machinery to operate smoother and at higher speeds than a standard bearing will allow.
