Product Overview

We are proud to offer AndyMark's latest and greatest 6 in. diameter Mecanum wheel. This wheel's features are a culmination of our hard work in developing the Mecanum wheel since we introduced an affordable wheel to the market in 2006. It has the same heavy duty features, but with an added smoothness while rolling. We minimized the gaps between the rollers, enabling this wheel to be our "smooth rolling" (SR) Mecanum Wheel.

RoHS compliant

A wheel set is comprised of two left (am-3479Lb) and two right (am-3479Rb) wheels. Should you need a replacement wheel, a single left or right can also be acquired. These wheels have a weight capacity of 200 pounds per wheel.

NEW! This is revision 'b' which fixes a problem we've had in very few cases where the mounting holes between hub plates was not lined up properly. We've fixed this by improving our assembly processes and now use rivets to secure the hub halves together.

Individual Components within Wheel Set:
  • Two - Left 6 in. SR Mecanum Wheels (am-3479Lb)

Roller and Axle Design:
The gray urethane rubber roller (am-3698) has a durometer rating of 80a. The roller has a polycarbonate core, and 2 high load bushings. The bushings ride on brass tubes, sandwiched between the plates with a #10-32 machine screw.

Wheel Structure:
15 rubber rollers are sandwiched between 2 steel plates. The two interior pieces are sandwiched together at the bore with a thickness of 0.25 inch. These wheels can be purchased in a set of 4, or individually. They are sold without hubs, sprockets, or bearings.

Driving with Axle and Hub Overview:
If driven by a round shaft, these parts are needed for each wheel
  • A hub fitting the size of the drive shaft. For 1/2 in. dia. shafts, use a 500 Key Hub (am-0976) for each wheel.
  • #10-32 x 5/8 in. long screws (6), and #10-32 nylock nuts (6) fasten the hub to the wheel.
  • 1/8 x 1/8 x 3/4 steel machine key (am-1043), one per wheel
Driving with a Sprocket:
If driven by a sprocket, these parts are needed for each wheel.
  • Flanged ball bearings with 1.125 in. od: either 3/8 in. inside diameter (am-0573), or 1/2 in. i.d. (am-0030)
  • Two 550 sprocket spacers (am-0651) are used to space the sprocket away from the wheel, for chain clearance.
  • A sprocket (type A) with a bolt hole circle of 1.875 in. diameter mounts to the wheels' interior bolt pattern.
  • #10-32 x 1.75 in. long screws (6), and #10-32 nylock nuts (6) fasten the sprocket and spacers to the wheel.
