Skate Bearings - Frequently Asked Questions

1,What Are ABEC Bearings?
The ABEC scale is a system for rating the manufacturing tolerances of precision fastest skateboard bearings. The system was developed by the Annular Bearing Engineering Committee or Council (ABEC) of the American Bearing Manufacturers Association (ABMA). The American Bearing Manufacturers Association was formerly known as the Anti-Friction roller skate bearingsManufacturers Association.

2,Are Ceramic Balls of Any Benefit in the 608 bearing?
Ceramic hybrid and full ceramic best skateboard bearings are relatively new technology. Provided the ceramic hybrid long board bearings also have a non metallic cage and are grease lubricated you should get extended life from them. If the cage is a standard steel cage, the ceramic balls may damage the cage quite quickly.

3,What are the Abec grades of bearings available. How different are the grades? 
From Lowest to Highest

   * ABEC 1 Approximately equal to ISO P0
   * ABEC 3 Approximately equal to ISO P6
   * ABEC 5 Approximately equal to ISO P5
   * ABEC 7 Approximately equal to ISO P4
   * ABEC 9 Approximately equal to ISO P2 

There are a number of factors covered by the abec bearings grades, but to give you an idea we will just examine one of these factors - the eccentricity (out of roundness) of the track in the inner ring. For an ABEC 1 (lowest grade) bearing, the maximum eccentricity allowable is 0.0075 mm (0.000295"). This is quite precise - more than precise enough for skates and skateboards. The figures for other grades are

   * ABEC3: 0.005 mm (0.000197")
   * ABEC5: 0.0035 mm (0.000138")
   * ABEC7: 0.0025 mm (0.000098")
   * ABEC9: 0.0012 mm (0.000047") 

4,Are there any other standards for measuring Bearing precision? 
Yes. The other commonly used standard is the ISO (International Standards Organisation) standard. There are slight differences in the standards applied, but basically ISO Grade P0 is approximately equal to ABEC 1, ISO P6 approximates ABEC 3 inline skate bearings, ISO P5 approximates ABEC 5, ISO P4 approximates ABEC 7 and ISO P2 approximates ABEC 9.

5,Are Nylon or Polyamide Retainers good for Skating Applications?
A nylon or polyamide retainer has some advantages over a steel retainer. Skating is an application that involves a lot of vibration, and inline skate wheels bearings don't like vibration. Steel retainers are especially prone to damage under excessive vibration. Nylon or polyamide retainers are more tolerant of vibration. They also hold lubricant in place for longer.
