I purchased those exact mecanum wheels (i think about 5-6 years ago). a word of caution with heavier loads the press fit rollers can slide off the pins during use. this gets quite annoying when you need to stop the robot and search for the little washers and rollers that keep falling off.
The reason i actually purchased them was to construct a prototype/test platform robot before designing and building custom 14" mecanum wheels.

Usually they are used to make an omnidirectional robot.
Other than robots I have seen this type of wheel used on forklifts
