Heavy Duty Castors with swivels in USA – Uratech USA Inc

As our carts will be rolling in a rough industrial floor with all kinds of debris, Uratech USA Inc spend a considerable amount of time in developing a good quality castors where it can withstand weight about 2000lbs (905Kg )

Uratech USA Inc supplies 4 castors with each cart ( 2 swivels with brake ) and 2 rigid.

To ensure smoothness on rolling, Uratech USA Inc chooses Poly Urethane as a material for our castors with a ball bearing mounted in it.

Properties of Polyurethane

High Load Bearing Capacity

Polyurethane has a high load capacity in both tension and compression. Polyurethane may undergo a change in shape under a heavy load but will return to its original shape once the load is removed with little compression set in the material when designed properly for a given application


Polyurethanes perform very well when used in high flex fatigue applications. Flexural properties can be isolated allowing for very good elongation and recovery properties.

Abrasion & Impact Resistance
For applications where severe wear proves challenging, polyurethanes are an ideal solution even at low temperatures.

Tear Resistance
Polyurethanes possess high tear resistance along with high tensile properties.

Resistance to Water, Oil & Grease
Polyurethane’s material properties will remain stable (with minimal swelling) in water/oil/ grease. Polyether compounds will last many years in subsea applications.

Electrical Properties
Polyurethanes exhibit good electrical insulating properties.

Wide Resiliency Range
Resilience is generally a function of hardness. For shock-absorbing elastomer applications, low rebound compounds are usually used i.e. resilience range of 10-40%. For high-frequency vibrations or where quick recovery is required, compounds in the 40-65% resilience are used. In general, toughness is enhanced by high resilience.

Strong Bonding Properties
Polyurethane bonds to a wide range of materials during the manufacturing process. These materials include other plastics, metals, and wood. This property makes polyurethane an ideal material for wheels, rollers, and inserts.

Performance in Harsh Environments
Polyurethane is very resistant to temperature extremes, meaning harsh environmental conditions and many chemicals will not cause a material degradation
