Load capacities are up to three times that of similar rubber
tyred wheels, which means that smaller diameter wheels
can be used if required. Vulkollan tyred wheels also offer
excellent recovery from long periods of heavy static
loading combined with low rolling resistance and floor
saving.
Resistant to a wide range of oils, greases and chemicals,
Vulkollan Polyurethane is used on 150mm sized wheels and
above and performs satisfactorily between -30
o
C and +80
o
C
under normal conditions.
Polyurethanes are sensitive to hydrolysing agents such
as hot water, steam and hot moist air, strong acids
and alcohols. A special grade with high hydrolysis
resistance and no loss of load handling performance is
available to special order. To order replace the letters
PT
with
WC
in the catalogue reverence when ordering.
When fitting these wheels into brackets of the castor
ranges indicated above, the load capacity of the complete
castor must be downrated to the maximum rating shown in
either the castor range assembly table, or that of the
wheel, whichever is lower.
Headed Spacers
To fit ball journal wheels into
castors use a pair of headed
spacer bushes. These sleeve the
bore and increase
the hub width to match the
castor frame and axle bolt.
