VEX EDR Square Drive Shafts have rounded corners which allow them to easily spin in a round hole, while locking into a square hole. Insert these into a motor to power all of your applications.

• Lengths: 2", 3", and 12"
• Use the 12" to make your own custom length shafts
• Works with motors, wheels, gears, and bearings

Shaft Couplers are the same length as old VEX EDR clutches, allowing 2-Wire Motors to be used in places that previously had a clutch without changing shaft length.

• Makes replacing 3-Wire Motors quick and simple
• Placement between motor and drive shaft makes changing shafts easier

Clamping Shaft Collars use standard VEX EDR screws and nuts to maintain a tight lock without scratching or damaging the shaft.

• Designed specifically for VEX EDR Drive Shafts
• Standard VEX EDR screws use a 3/32" allen key
• Clamping collar is easily adjustable without damaging shaft

Rubber Shaft Collars easily slide onto VEX EDR 0.125" shafts. Friction between the rubber collar and steel shaft keeps wheels and gears from sliding off.

• Designed specifically for VEX EDR Drive Shafts

The Drive Shaft Bar Lock is the metal version of the shaft locking part. It includes three locations for square shafts.

• Extremely strong
• Made from cold rolled steel, 0.046" thick, zinc plated

Shaft Collars lock to drive shafts, keeping wheels and gears from sliding along the shaft. Collars fit around Drive Shafts and can be fastened in place using a setscrew.

• Designed specifically for VEX EDR Drive Shafts
• Set screw uses the same Hex Key as the 6-32 Motor Screws

1/4" Pitch Acetal Bearings are specifically designed to mount to VEX EDR 1/4" Pitch Metal. Use them with other components from the VEX EDR Motion Subsystem to create intricate and compact mechanisms.

• Low friction allows shafts to turn smoothly
• Mount with Screws & Nuts or Attachment Rivets
• Create intricate and compact mechanisms

The Bearing Flat mounts directly on a piece of VEX EDR structure and supports a shaft which runs perpendicular and directly through the structure.

• Low friction allows shafts to turn smoothly
• Mount with Screws & Nuts or Attachment Rivets

The Bearing Attachment Rivets make mounting Flat Bearings onto VEX EDR structural component easy. Reusable; simply push the pin out from the back side.

• Speed up robot assembly
• 50 ea of the Bearing Attachment Rivets
• Reusable

Bearing Blocks mount on a piece of structure and supports a shaft which is offset either above, below, or to the side of the structure. Lock Bars allow any VEX EDR component to be “locked” to a shaft so that it will spin with the shaft.

• Bearing blocks mount on a piece of structure to support a shaft
• Lock Bars allow VEX EDR components to be "locked" to a shaft
• These items are not sold separately

A Spacer is used to create a space between two objects, often to properly position them. Available in various lengths.

• Eliminate slop on shafts
• Add space between metal parts
• Plastic and Nylon options

A Washer is a thin disk with a hole used to distribute the load of a threaded fastener. VEX EDR washers fit on all VEX EDR screws and VEX EDR shafts.

• Steel washers are a good all-purpose washer.
• Teflon has low friction. Use on shafts where metal rubs on metal.
