The GT2 series of belts are designed specifically for linear motion. They use a rounded tooth profile that guarantees that the belt tooth fits smoothly and accurately in the pulley groove, so when you reverse the pulley direction, there is no room for the belt to move in the groove.
This belting is meant to be used in conjunction with a timing-belt pulley such as these parts.
Note: The Shapeoko 2 and X-Carve machines use 6.35mm wide belts.

“GT2” refers to “2nd generation” in terms of the tooth geometry. This can commonly be misconstrued as referring to the pitch. The would actually be labeled before the “GT” ( [pitch]GT[tooth geometry revision] ).
For example:
The 6mm belt (26053-03) would be labeled as 2GT2, and the 9mm belt (26053-05) would be labeled as 3GT2.
