Polyurethane Caster Wheels with Iron Centers |
|
| Polyurethane is superior to rubber in resistance to
grease, oil, cutting, chunking, and abrasive wear. These caster wheels can be
used on almost any factory floor. As with moldon rubber, the bonding agent
which holds the polyurethane tire ( tread ) to its iron center can be affected
by exposure to some chemicals, impact, overloading, and the buildup of heat.
Tire hardness is 90 to 95 Durometer, Shore A for wheels with prefix PY, PYR and
PYC. Tire Hardness is 60 - 65 Durameter, Shore D for wheels with prefix PHY.
Temperature range is -20° to 180° F. The principle benefit of a
polyurethane wheel over the same size rubber wheel is increased capacity. Given
the same size load on a smooth floor, a polyurethane caster wheel rolls easier
than the same size conventional rubber caster wheel. However, when used at full
capacity, polyurethane is not easy rolling. Given a manual operation under
ideal conditions, polyurethane caster wheels have a safe operating capacity of
up to three times the capacity of the same size rubber wheel. Capacity ratings
are offered as an idea of what the wheel will carry without failure. They are
not absolute, but rather depend on the usage and service. Your conditions are almost never ideal, so select a caster wheel with much higher capacity than the weight you require. Polyurethane is not truly floor protective because it lacks the resilience and cushioning effect of soft rubber. However, polyurethane is less damaging to floors and cargo than "hard tread" wheels because it provides some tire deflection under load. Polyurethane caster wheels are not recommended for storage (standing) loads except for wheels with prefix PYH. Wheels with PY and PYR prefix are popular for most polyurethane wheel applications. Wheels with PYC prefix have a slight crown to the tire ( tread ) which enhances the ability of a swivel caster to change direction. Prefix PYH designates Extra Heavy Duty wheels. They have extra thick iron centers and tires. The 60 - 65 D durameter tires provide higher capacities for extra heavy duty applications. |

 Caster wheels are
standard with straight roller bearings and a spanner bushing. Other bearing and
wheel sizes are available on request. |
| 2"
wide wheels are furnished with Combo washers making the Hub Length 2 7/16". If
you want 2 3/16" Hub Length, specify "With Flat Washers" on your order in the
"Special Instructions" on the checkout page. 2 1/2" & 3" wide wheels are furnished with the Hub Length shown in the table above. Flat Steel Thrust Washers and a Spanner Bushing are included. |
You should never select on the basis of load capacity
alone. Capacity ratings do not take into account the effort required to
manually move a load. Capacity ratings are based on manual operation under
ideal conditions. If these wheels are going to be moved by mechanically powered
equipment, consult us for a reduced capacity rating based on your
application. |
