JUWAmid® Wheels

Superior performance and durability over traditional polyurethane, composite, or steel wheels

Wheel Technology & Construction

JUNG rotating dollies are outfitted with black JUWAmid wheels. This wheel material is superior in its performance characteristics - i.e. it turns and rolls more easily - over any traditional nylon, composite or polyurethane wheels for the intended use.

Why?

Rotating dollies are designed to change direction on a dime or circle in place which requires the wheels to also spin and turn in place. Furthermore, when the rotating dollies are first positioned, the wheels may point in various directions. To get the load rolling, these wheels have to all spin and align into the direction of movement. This initial resistance is called "break-out resistance" and it is significantly higher than on standard dollies that already have all wheels already pointing in the same direction.

Under heavy weights, traditional wheel materials exhibit a so called "rubber effect" during maneuvers. The friction between the wheel and the floor is so great that turning and "starting-to-roll" operation becomes very difficult and it significantly reduces the ease of movement.

JUWAmid was developed to reduce this resistance. The material is based on a polyamide compound and further chemical engineering of the composition resulted in a wheel that is very slick (like touching ice). This characteristic reduces the rolling resistance and the break-out resistance to make it roll and turn easily.

This makes the overall manhandling effort required to move multi-ton loads very easy and it sets the performance from other products apart.

The material formulation also took into consideration the need to keep the wheel from marring, marking and damaging floors and the material is resistant against embedding of debris.

JUWAmid is exclusively available on JUNG rotating dollies.

Ball Bearings

JUNG wheels are outfitted with sealed ball bearings to prevent any contamination from sand or dust that would result in a failure of the bearings. Furthermore, standard ball bearings are not very uniform causing unequal load distribution and high failure rates. JUNG only employs precision ball bearings with low tolerances to assure constant even load distribution.

Design

To further improve the ease of turning, the previously used wide wheels have been replaced by more narrow, side-by-side wheels that now have the ability to turn in opposite direction during tight turns.

Side-by-Side Wheels to Reduce Friction

White JUWAmid Wheels Available

The standard black JUWAmid wheels are also available in white. White wheels turn dark from picking up dust so the white wheels usually do not stay white. We consequently recommend the standard black wheels.

Please note that white JUWAmid wheels are special order and additional lead times apply.

Upgrade to Yellow JUWAthan+ Wheels

Black JUWAmid wheels are recommended and come standard on all rotating dollies. See description on left. However, customers that need extremely high floor protection can order the rotating dollies with yellow JUWAthan+ wheels (standard on all our other types of dollies).

Please note that yellow JUWAthan wheels are special order and additional lead times apply.

Main Characteristics

Specially formulated material for optimal manoeuvrability:
  • Slick-to-touch material for spinning in place, with reduced "rubber" effect on floors for easy change of direction.
  • Precise turning without additional need for aligning by hand.
  • Low man-handling force required to push-pull in confined spaces
  • Non-floor damaging, non-marking
  • Reliable under toughest working conditions

Comparison to Conventional Wheels

JUWAmid Conventional
