Shafts / Spacers / Collars

Shafts

MAXSpline Shaft

MAXSpline Shaft (REV-21-2520) is compatible with the REV ION System and is an extruded aluminum MAXSpline that provides a high strength alternative to 1/2in hex shaft that can interface with any REV ION system components. The inner diameter is 1in and can fit a Needle Bearing for dead axle applications.

1/2in Rounded Hex Shaft

The 1/2in Rounded Hex Shafts (Product Family Page) are a ready-to-use hex shaft that have been cut to length and have the ends tapped #10-32 in order to accept a screw and washer or a shaft collar. We've rounded the corners to form a 13.75mm circle that allows the shaft to pilot inside our Flanged Bearings (REV-21-1916) resulting in an exceptionally smooth assembly and driving experience. Additionally, an untapped 36in shaft is available if you need to create a custom cut length.

1/2in Hex Shaft Adapters

Convert different output types to 1/2in Hex Shaft to interface with the REV ION Build System using our different 1/2in Hex Shaft Adapters.

UltraPlanetary 1/2in Hex Adapter

Easily attach the UltraPlanetary 1/2in Hex Adapter (REV-41-1620) to the output of your UltraPlanetary Gearbox to provide a convenient 1/2in hex output shaft

8mm to 1/2in Hex Adapter

With the 8mm to 1/2in Hex Adapter (REV-21-1879) you can convert 8mm keyed shafts to drive 1/2in hex bore wheels, sprockets, gears, and more! Use these with any motors that have a 8mm round keyed output shaft, like the NEO Brushless Motor (REV-21-1650).

Spacers

MAXSpline Spacers

MAXSpline Spacers (Product Family Page) are compatible with the REV ION System and can be used on the shaft as a spacer for wheels and sprockets as well as an in-between spacer for bearings.

MAXSpline Spacer with MAX Pattern

Primarily used with ION wheels and sprockets, the MAXSpline Spacer with MAX Pattern (REV-21-2547-PK4) features a 2in bolt circle pattern allowing it to be bolted directly to structural members like MAXTubes and the bolt circle allows it to be mounted to motion components as well.

1/2in Hex Shaft Spacers

1/2in Hex Shaft Spacers (Product Family Page) are primarily used with a hex shaft as a spacer between components with 1/16in, 1/8in, 1/4in, 1/2in widths available.

8mm Shaft Spacer

The 8mm Shaft Spacer (Product Family Page) is compatible with the REV ION System and is a convenient way to space pinions and gears along the shaft of the NEO Brushless Motor.

#10 Spacers

Compatible with the REV ION System and are an accurate way to space structural components like plates, brackets, or tubes apart on #10 screws. Our #10 Spacers (Product Family Page) can also be used to to space motion components like gearboxes away from their mounting surface. Mix and match various spacer lengths to adjust spacing in increments as small as 1/8in.

Collars / Shaft End Screw

#10-32 Shaft End Screw (REV-21-2056-PK10) ION 1/2in Rounded Hex Shafts come tapped with a 10-32 hole. Use this special screw to retain things on any of our hex shafts instead of shaft collars. The integrated flange is larger than the outside diameter of the shaft and will keep motion components from sliding off the end of the shaft and a nylon patch helps keep it secured in high vibration environments.
MAXSpline Shaft Collar - 2 Piece - Aluminum (REV-21-2581) The MAXSpline Shaft Collar provides a simple way to retain items in place on the MAXSpline Shaft. The shaft collar can also be bolted to structure to constrain the axial alignment of MAXSpline Shaft when used in a structural method.
2 Piece Shaft Collar - 1/2in Hex Bore (REV-21-1912-PK4)The 2-Piece 1/2in Hex Plastic Shaft Collar is used to prevent gears, sprockets, wheels, and other parts from sliding out of place on a 1/2in hex shaft. The two-piece design allows you to install the shaft collar onto a shaft without having to remove other parts or having access to the ends of the shaft. Tighten the two screws to secure the shaft collar onto the shaft. Screws require a 5/32in hex driver (not included).
1 Piece Shaft Collar - 1/2in Hex Bore (REV-21-1911-PK4) The 1-Piece 1/2in Hex Plastic Shaft Collar is used to prevent gears, sprockets, wheels, and other parts from sliding out of place on a 1/2in hex shaft. Tighten the screw to secure the shaft collar onto the shaft. Screw requires a 5/32in hex driver (not included)
