Conventional Moldon Rubber Caster Wheels
Caster Barns Conventional Moldon rubber caster wheels have soft black rubber tires molded onto cast iron centers. Soft rubber provides more desirable operating characteristics than any other wheel material. It is quiet, absorbs shock (prolonging equipment life and protecting cargo), can roll over small objects, protects costly floor surfaces, and minimizes vibration.
The Conventional Moldon rubber caster wheel falls short of perfection in its limitation under load - it does not roll easily compared to harder durometer wheel materials. Load capacity ratings do not take into account the effort required to manually move a load (draw-bar pull measured in pounds). If cargo is to be moved manually on Conventional Moldon rubber caster wheels, reduce capacity ratings by 50% and select the largest practical wheel diameter, the larger the diameter wheel the easier it is to roll.
These caster wheels should not be left standing under load for extended periods as the tires may take a permanent "set" or develop unwanted flat spots. They can be used on almost any dry factory floor. The bonding agent which holds the rubber tire to its iron center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat. Tire hardness is 65 to 75 Durometer, Shore A. Temperature range is -20° to 159° F.
• Rubber tread vulcanized to heavy duty cast iron core.
• Offers shock absorbing semi-cushioned ride, rolls easily over small debris, rough
floors, cracks, floor joints, etc.
• Provides good floor protection and quiet rolling operation.
• Economically priced cushion wheel.
• Works well in outdoor environments; however cast iron core can rust; if this is
an issue look at using aluminum or plastic core wheels.
• Durometer: 80 Shore A (+/-5).
• Temperature range: -40° F to 180° F.
