Description
Newport News Industrial CW1A-463X16000 general purpose resilient C-Worthy™ Shock Mounts Utility
TESTING
Although the C-Worthy™ mount is a commercial item, it is
compliant to many MIL Spec criteria and has performed well in
901D Barge Testing. The following are examples of proof testing
conducted during C-Worthy™ development:
SPECIFICATIONS
• Weight capacities from 5 to 700 Pounds
• Material Dupont Hytrel®
• Frequency 5 – 7 Hz
• Temperature range -30ºF to 150ºF
• Maximum Drift 0.1 inch @ 150ºF
• 10 to 30 Year Service Life
PRODUCT SUMMARY
The C-Worthy™ shock mount is a commercial shock and
vibration isolator that is rugged enough to enable the use of
commercial off-the-shelf equipment in Naval applications to
reduce life cycle cost.
INSTALLATION GUIDE
This document is provided to highlight information that is necessary for effective C-Worthy™ Shock Mount installation. It is important
that the customer adhere to the following criteria as described below to ensure the mounts are able to perform consistent with
intended functionality.
1. C-Worthy™ mounts require a liner/spacer to be installed under the long leg flange for proper operation. (Some installations use
alternate mounting means. If this is the case, be certain that the minimum elevation requirement is maintained. There is no
maximum.) Style 1 spacers are a minimum 0.75-inch thick. Style 2 spacers are a minimum 0.50-inch thick.
2. Ensure that bolts are inserted in the direction shown in the envelope dimensions figure below.
3. Do not use any spacers, washers, or lock-washers between the bolt head and the bushings as these conditions can reduce the
axial travel limits of the mounts.
4. Clearance Requirements – There should be no obstruction that could limit travel of the mount or the isolated equipment for 4 inches
in all directions for the Style 1 mount. The Style 2 mount and equipment requires a 3-inch clearance in all directions.
5. Uniformly load all mounts by either blocking equipment or hoisting to ensure mounts are neither over or under loaded during setup.
For example, do not locate sway mounts by setting cabinets on base mounts first. Upper mounts provide support for both vertical
and sway loads.
6. Orientation of sway mounts should open C facing down. (See standard orientation figure located on Application Engineering Data Sheet.)
7. Mounts should be positioned in the corners of the cabinet as far apart as practical. Refer to standard orientation figure for optimal
mount spacing illustration. Standard orientation figure is a suggested orientation. Actual mount orientations may differ from that
shown. (Mount spacing is a more critical concern when sway mounts are not utilized.)
