LEGACY TOOL FEATURES
KEYLESS ARBORS AND
UNIVERSAL LOWER ROLLS
In the 1990s, Victaulic introduced an improved
“keyless” method for transmitting grooving
power between the arbor and lower roll. This
“keyless” design applies to the lower rolls
and arbor only. All existing upper roll sets are
compatible with all lower roll types, as described
in this section. The possibility of losing or
shearing Woodruff keys is eliminated with this
“keyless” method.
The “keyless” lower grooving rolls still allow
hands-free grooving for short pipe lengths, as
listed in the “Pipe Length Requirements” section.
1.
It is important to determine which type of
arbor is available for the tool.
The keyed-type arbor contains a Woodruff key
and can be used with new, universal-type lower
rolls and older-type lower rolls.
The keyless-type arbor contains a square drive
and can be used ONLY with the new, universal-
type lower rolls.
2.
It is important to determine which type of
lower rolls are available for the tool.
The “key-drive only” lower rolls, shown in the
photo above, have a circular bore and can be
used ONLY with the keyed-type arbors that
contain the Woodruff key. Refer to the photo in
the previous column for the keyed-type arbor.
The “universal” lower rolls, shown in the photo
above, have a square bore that allows for easy
installation onto the “keyless” arbor. In addition,
these “universal” lower rolls contain a keyway
for use with keyed-type arbors.
CAUTION
• DO NOT attempt to install a “key-drive
only” lower roll onto a tool that has a
“keyless” arbor.
Failure to follow this instruction could result
in damage to the arbor and lower roll.
