What is the purpose of the 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, a standard ABEC 1, 608ZZ is rated with a limiting speed of 32,000 RPM with grease lubrication and 38,000 RPM with oil lubrication. The actual speed that 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 SPEED MACHINERY TO OPERATE AT FASTER SPEEDS THAN STANDARD BEARINGS WILL ALLOW.
