Welded Steel Drum Pulleys
Hewitt-Robins drum pulleys are designed
utilizing a single-piece rolled plate rim,
continuously welded end discs and extra
strength intermediate discs, as required. End
disc accuracy is assured by utilizing computer
controlled processes. Pulleys are tested for
T.I.R. requirements and supplied with hubs
bored as specified by the customer. As a
standard, drum pulleys are crowned* to assist
with proper belt alignment. Straight face
designs are available, but must be specified.
*Hewitt-Robins pulleys are crowned 1/16”
to 1/8” on the diameter per foot of total face
width.
Hewitt-Robins provides vulcanized rubber lagging
as an option. Lagged pulleys are most often used
on the head shaft pulley where friction is desired
between the belting and pulley or to prevent slippage
and prolong wear life when excessive foreign
materials are present. Lagging can be furnished in
various thicknesses and types.
As an option, Hewitt-Robins can supply slide lagging
pulleys. This type pulley can reduce downtime and
save money if pulley lagging needs to be replaced
immediately or if the pulley is in a restricted space.
Slide lagging can be applied on-site and typically
allows a pulley to return to servicemuch quicker than
utilizing conventional pulley lagging methods.
Ceremic, urethane, and a variety of other lagging types are available. Contact your Hewitt-Robins
representative for complete details.
