4 in. HD Mecanum Wheels

Product Overview

The 4" HD Mecanum wheel comes fully assembled and ready to go and comes in three different bore sizes.

A full set consists of 2 "right" wheels and 2 "left" wheels. The "right" and "left" refer to the direction the rollers are pointing when viewing the wheel as if your about to get run over by the wheel itself. If the roller in the middle of the wheel points up and to the right, it's a "right" wheel, and up and to the left would be a "left" wheel.

The configuration of these "right" and "left" wheels is important to a mecanum drive system! Be aware that the "right" wheel should not mean that it goes on the right side of your robot. The proper configuration would be to have the wheels create an "X" pattern when viewing your robot from above and drawing lines parallel to the rollers as viewed.
This means that a "right" wheel would be the FRONT RIGHT, and the REAR LEFT position, while the "left" wheel would be in the FRONT LEFT, and REAR RIGHT, of your robot when viewed from above. All 4 wheels are required to make a Mecanum drive holonomic system to work properly.
Using these for an intake? This has been a great use of these wheels as well! The angle of these wheels help drive the object in one direction, so you can pull in the object at the same time as pushing at an angle from the intake.
This version of the wheel can handle a 200 pound load per wheel for a total 800 pound load if using as drive wheels! The interior body of this wheel is made of molded black polycarbonate, while the perimeter side plate is made of 1/8 inch thick steel, zinc plated. The perimeter plate is riveted to the interior body, and each perimeter bent tab rests on the interior body rim. This support allows for the wheel to handle more load.
