2480.015 Pressure Plates, shock absorbing
Description:
Shock Absorbing Pressure Plate is designed to minimise the main
problems in the metal forming industry.
A specially designed shock absorbing unit is designed to reduce:
– extreme impact loads
– consequent high costs for press maintenance
– high noise levels
– risk of production of lower quality parts.
Guidelines for using Shock Absorbing Pressure Plates with gas
springs:
1. After the maximum shock absorbing travel of 3 mm the gas
spring will reach the same initial spring force as it would wit-
hout the Shock Absorbing Pressure Plate.
2. The Shock Absorbing Pressure Plate is mounted between the
tool and the piston rod of the gas spring.
Material:
Steel, nitride
Polyurethane
Note:
Working temperature: 0 °C to 80 °C
Recommended max. strokes/min: 20
Max. press speed: 1.6 m/s
Max. shock absorbing travel: 3 mm

Thrust Pads and
2480.004.
Thrust Plates for Gas Springs
2480.009.
Description:
The hardened thrust pad 2480.004. reduces side forces in cases of
skew thrust vaces or lateral displacement component.
In conjunction with the thrust pads, the hardened thrust plates
2480.009., 2480.018. and 2480.019. further helps to protect the
gas spring from lateral forces, through reduction of friction – even
when used without the thrust pad.
Note:
Especially with gas springs of large stroking capacity we recom-
mend the
use of the pad plate combination!

Gas spring connection systems
Introduction
Connecting gas springs in one more systems enables the user to monitor gas spring pressure from
outside the tool, to adjust it if necessary, to fill it and to drain it. The connector system has many advan-
tages including ease of maintenance, reliability and improvement in the quality of gas sping use in the
tool.
FIBRO offers four different systems for hose connections for gas springs: Minimess system, Compression
fitting system, JIC system (24° flare) and Micro connector system. The hoses, screwed connectors and
other components are selected to meet the most stringent standards and undergo a series of tests inclu-
ding service life, static seel and robustness after repeated assembly and disassembly.
Recommended application:
Most used system for all gas springs with G

Instruction for Hose Assembly
Mounting arrangement
for gas springs in the Minimess system
Never exceed the maximum pressures and temperatures for the
hoses.
Ensure that all hoses and adaptors are perfectly clean prior to
assembly.
To be suitable for use with compressed gas the hose sheath must be
perforated. We recommend the use of the 24°-cone-hose system for
pressure reservoir to ensure an unrestricted gas flow.
Follow the instructions below to ensure functionality and maximum
service life for the hose connection:
Refer to DIN 20066 for further details on installing hose connec-
tions.
Warning:
Any modifications whatsoever to the product are prohibited.
For further information refer to the FIBRO Gas Spring Catalogue,
visit www.fibro.com or contact your FIBRO agent.

The longitudinal marking on the hose must
not be twisted during assembly.

Any bends in the hose must always have the recommen-
ded minimum radius, as detailed in the catalogue.
