Buying new Bearings

My K2 skates have 8-mm, TwinCam, ABEC-1, double-shielded bearings with the following inscribed on the casings:

TwinCam

ABEC-1

608 ZZ

Normally, the manufacturer or brand doesn’t make a lot of difference within the three categories of shielded, serviceable bearings, shielded, serviceable bearings with pop-up caps, and sealed, non-serviceable bearings. A bearing size of 8mm and the 608 designation are fine for recreational, inline skaters. The ABEC rating is another story!

ABEC Bearing

ABEC-1, 3, and 5 are the most common bearings that come with inline skates, as well as the newer ABEC-7s, which are gaining in popularity. Whether a skater can go faster with ABEC-5 bearings versus ABEC-1 bearings has never been proven, scientifically or otherwise.

Furthermore, the higher precision may not make a significant difference for the recreational skater who travels in the 10 to 20 mph range. The average skater doesn’t require a higher-rated bearing because the difference in performance is so minimal that it would only become apparent at speeds an inline skater never attains.

In addition, the higher precision eventually deteriorates down to ABEC-3 or 1 due to dust, dirt, and regular wear and tear. To increase your skating speed, you’d be better off to improve your technique and learn how to cut down on wind resistance. These are proven ways to make you a faster and more efficient skater.
