The set of 254mm steel mecanum wheel includes 2 right wheels and 2 left wheels. Each wheel is comprised of 12 nylon rollers, mounted so that their axis of rotation is 45 to the axis of the main wheel as well as moving forward and backward like conventional wheels, steel mecanum wheel allow sideways movement by spinning wheels on the front and rear axles in opposite directions. These mecanum wheels is a heavy duty wheel itself, they are sold in assembled units with aluminum axle.These axles and rollers are sandwiched between two thick steel plates. The rollers are made of black nylon, the steel body mecanum wheels of load capacity is higher than aluminum mecanum wheel.

The Mecanum wheel is one design for a wheel which can move in any direction. It is sometimes called the Ilon wheel after its Swedish inventor, Bengt Ilon, who came up with the idea in 1973 when he was an engineer with the Swedish company Mecanum AB. The angle between rollers axis and central wheel could have any value but in the case of conventional Swedish wheel it is 45”.The angled peripheral rollers translate a portion of the force in the rotational direction of ht wheel to a force normal to the wheel direction .Depending on each individual wheel direction and speed,the resulting combination of all these forces produce a total force vector in any desired direction thus allowing the platform to move freely in the direction of the resulting force vector,without changing of the wheels themselves.
Benefits:
Compact size.
High load capacity
Add omni direction capabilities to your vehicle
Application:
Robotics
Wheelchair
Transfer vehicle
Using four of mecanum wheels provides omni-directional movement for a vehicle without needing a conventional steering system slipping is a common problem in the mecanum wheel as it has only one roller with a single point of ground contact at any one time. Due to the dynamics of the mecanum wheel, it can create force vectors in both the x and y-direction while only being driven in the y-direction. Positioning four mecanum wheels, one at each corner of the chassis(two mirrored pairs),allows net forces to be formed in the x,y and rotational direction.
Various hub available to ease mounting to motor.
