Introduction
Purpose of manual
This manual has been prepared to
assist users of Vickers Series TZ
cylinders for properly maintaining and
repairing their units. In the sections that
follow, instructions are given for proper
installation, maintenance and overhaul.
General information
Model codes have many variations
within a basic model series. They are
covered by variables in the model code.
Service inquiries should always include
the complete model code number as
stamped on the head or cap and three
digit plant code.
How to order
Vickers has developed an easy system
for ordering Series TZ Cylinders. This
system has been developed to improve
ease of ordering. The model code
consists of sixteen alpha-numeric digits
which fully describe the most common
standard options offered.
To specify your Series TZ cylinder,
review the Model Code section for a full
description of each option available and
corresponding code.
Custom cylinders
Although the model code has been
arranged to cover the vast majority of
available options, there will be
occasions when an option which cannot
be coded will be required. When such
an option has been specified, enter an
“X” for the appropriate item in the model
code. For example, an application which
requires a custom thread on the end of
the piston rod, an “X” is inserted for item
7. The cylinder will include a unique five
digit design number.
Replacement cylinders
Every custom cylinder is assigned a
unique design number. This number is
contained in the last five digits of the
sixteen digit model code. Item 12 is
always an alpha character. The “Stroke”
and “Extra Rod Projection” positions
(items 12 through 16) become the
“Design Number” items for custom
cylinders. When ordering a replacement
part or cylinder, give the sixteen digit
model code or the five digit design
number to your local Vickers
Representative.
Replacement parts
Each design number has a completed
bill of materials on file in a quick retrieval
computerized storage system. This
gives the Field Sales Representatives
rapid access in identifying and
specifying genuine Vickers
replacements parts.
