Bearings (32 Choices)
Bearings constrain relative motion and reduce friction between moving parts.
VEXpro offers all the bearings most commonly used by FIRST ® teams, and also replacement bearings for all the "odd sized" bearings used in VEXpro gearboxes.
Note: Please be aware that ThunderHex bearings are 13.75mm round bearings, designed to fit a ThunderHex shaft. For more information about ThunderHex, please click here.

ThunderHex Stock works in all applications where 1/2" Hex Shaft will work and also includes rounded corners. These rounded corners allow the shaft to pilot inside a 13.75 mm round (ThunderHex) Bearing instead of a standard 1/2" Hex Bearing. This eliminates some difficult manufacturing tolerances and results in a MUCH smoother end result. Simply put, ThunderHex Bearings are the best way to create smooth-running hex shafts, and ThunderHex Stock helps you accomplish this without a lathe.




Also, since you're essentially putting a round peg in a round hole, no more struggling to align the hex of your shaft with the hex hole of your bearing.
