Main Characteristics

Comparison to Conventional Rollers

Patented material baked in oven onto core for toughness & elastic performance characteristics:

Overcomes obstacles easily (rollers mold around obstacles and keep rolling)
No stop, up & over action required like with other rollers
Spreads out under weight for large footprint resulting in low floor pressure, low break out & low rolling resistance, low push-pull force and low manpower requirement
Shock absorbent for impact loading
Non-floor damaging, non-marking
Reliable under toughest working conditions

Construction

CORE: Aluminum core on dollies up to 12 tons (for lightweight handling) *Steel core on dollies 20 tons and over

BEARINGS: Advanced high-strength precision ball bearings, ball bearings are sealed from both sides to protect against contamination of sand & dirt

OUTSIDE MATERIAL: JUWAthan+®, bonded into deep grooves in steel/aluminum core against sideways pressures

HARDENING: Rollers baked in oven for extended period of time

For Floor Conditions

	For floors smooth and rough
	For floors with dirt incl. workshop with metal shavings on floor
	For floors with cracks, countersunk rail tracks
	For inside and outside
	NOT for grass or gravel

Recommended Roller Types for Specific Floor Conditions

Smooth, clean and sensitive floors		Easy Steering
Workshop facility with dirty floors
Damaged and roughened floors

	JUWAthan+	Conventional polyurethane
Holds up to capacity	YES	YES
Will actually roll and not drag behind at max capacity	YES	NO
Baked in oven for toughness &long durability	YES	NO
	Elastic & Tough	Hard & Brittle or Soft & High Wear
Elastic roller material intentionally sags under weight to increase footprint, spreading out weight	YES	NO, sags under heavy load and deforms
Overcomes small obstacles easily with No stop, up & over action required	YES	NO
Shock absorbent for impact loading	YES	Cracks Rollers / Frame
Leaves obstacles like metal shavings behind	YES	NO
Non-damaging & Non-marking	YES	Non-marking only
Low floor pressure	YES	NO
Low break out (stand-still to roll) resistance (Pull force as % of weight)	3-10%	15-25%
Easy steering	YES	Crowbar & Power Assisted
Manpower requirements	LOW	HIGH
Use of double ball bearings to imply higher capacity	NO	YES, rollers will drag behind due to higher floor pressure
Sealed ball bearings (both sides) shielded against sand & dirt	YES	NO, risk of failure from grinding balls in dirt
Long life & durable	YES	NO
Operating cost over time	LOW	HIGH
Reliable under toughest working conditions	YES	NO

Roller Hardness (Durometer)

Our patented rollers are softer, more elastic, more floor protective at higher durability.

*Scale D measured under ISO 2039-2
