ThunderHex Stock & Bearings will revolutionize the ways teams use hex shaft.

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.

1/2" Hex shafts. 3/8" Hex shafts. 1/2" Tube shafts.

• 7075-T6 Aluminum
• Black Anodized
• 18" or 3' lengths

Commonly used bearings and replacement bearings for VEXpro gearboxes.

Connects two sections of 1/2” Hex shaft together. Clamping design provides axial retention of both shafts, while providing high torque transfer capability.

• Clamped together with (8x) $4-40 x 0.375" Socket Head Bolts
• Allows for 3/4" of engagement from each shaft
• Use included holes to pin each side in place
• Flats on each side allow for the use of a wrench to turn the coupled shafts

Shaft Collars that Clamp

• 8mm Round
• 3/8" and 1/2" Hex
• 3/8" and 1/2" round

Useful for spacing out items axially. They come in black. We think they're pretty cool, but they're really not very exciting.

• Various Thicknesses
• Fits 1/2" or 3/8" Hex and Round Shafts
• Sized to easily slide onto VEXpro shafts

The 8mm to 1/2" Hex Adapter turns any standard CIM style motor (with an 8mm shaft) into a direct 1/2" hex drive. The perfectly toleranced 8mm round bore and keyway slide easily onto the CIM-style shaft and allow for use with items that have a 1/2" Hex Bore.

• ID: 8mm with 2mm keyway
• OD: 1/2" hex
• Length: 1.0" (25.4mm)
• Black anodized for superior performance
