  • ABEC scale

    Lower graded bearings are intended for the vast majority of applications such as vehicles, mechanical hobbies, skates, skateboards, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high RPM and smooth operation. ISO's equivalent standard is ISO 492.

  • Viscosity Charts

    For example, a lubricant with an ISO grade of 32 has a viscosity within the range of 28.8-35.2, the midpoint of which is 32. Rule of Thumb: The comparable ISO grade of a given product whose viscosity in SUS at 100°F is known can be determined by using the following conversion formula: SUS @ 100°F/5=cSt @ 40°C. cst= 0.226xSUS-(195/SUS)

  • What an ABEC Rating Tells You About Skateboard Bearings

    ABEC 1 is the most crude, the least precise, the most durable, and the cheapest. ABEC 3 is what most cheap complete skateboards come with, especially skateboards from China. ABEC 3 bearings work for most skateboarding, but won't roll very smoothly or fast. ABEC 5 bearings are the norm in skateboarding. You get a reasonable amount of speed, and
