Question 1

Why are they labeled ESS bones swiss? I have never heard of ESS before

Accepted Answer

ESS is the company selling these bearings.

Question 2

Sorry about this but "608 mm" comes out to about 2 feet - Bones Reds come in either 7 mm ID or 8 mm ID. I believe you mean to say these are 8 mm ID.

Accepted Answer

Well - if you really want the nittythe 3 digit number is a common designation/model number for bearing. Since it starts with a digit it describes bearing using metric measurements.The first digit identifies the style of bearing    6 - "deep grove" - this means the bearing will take thrust both radially and axially all by itself and doesn't really care which. This is the most common style for skate/skateboard applications.The next digit describes the kind of usage the bearing is designed for.    0 - "extra light" duty    2 - "light" dutyThe next digit is the ID in mm. The most common IDs for skate/skateboard applications are    7 - 7 mm    8 - 8 mmThis number may be followed by a letter or two describing the seals or shields. It is commonly omitted except when ordering. "Z" indicates 1 shield, "ZZ" indicates 2.Bones Bearing usually have only one shield.Skate bearings are usually 608 or 627. The same for skateboards but skateboarders are experimenting with some different constructions. The ones I've seen have builtin spacers.A good resource for this (not so universal) number system can be found at http://www.gizmology.net/bearings.htm
