GMT Buffer • Description of parts and functions:GMT buffers are simple and affordable elements, whose individual metal parts are permanently held togetherwith a firmly adhering layer of elastomer. They are especially suitable for storage of light and moderately heavyequipment without any distinctive dynamic load. Their robustness and wide range of dimensions make anuniversal application possible.
• Description of parts and functions:GMT rebound stops and GMT crane stop buffers are used as final stops e.g., for trams and cranes. They canabsorb a large part of the effective kinetic energy from impact due to their special construction and theirexceptional buffering capacity. This avoids damage from excessive vibration and rebound in machines andinstallations.
• Dimensions:
- TYPE: Crane stop buffers with outside thread
Elastomer: - natural rubber (NR)- age-resistant- can be used from –30°C to +70°C- hardness = 70 ± 3 Shore A

For outer threads >= M12 the following applies: the well smooth operationa properly functioning standard nut is considered guaranteed.
Pressure load curves for 55 Sh-ACorrection factor for 40 Sh-A = 1.9Correction factor for 70 Sh-A = 0.5
• Spring characteristics:
There is a possible deviation of approx. +/-20% in the above values due to production and hardness tolerances.

GMT – Suction bases • Description of parts and functions:The GMT suction bases primarily serve to bear relatively light aggregates. Due to their special bearingsurface, properly borne equipment can be prevented from sliding. The possibility of adjusting their levelminimally, for example for measuring devices to be aligned, is yet another of their advantages. Upon request,suction bases with an inner thread are also available.
For outer threads >= M12 the following applies: the smooth operationof a properly functioning standard nut is considered guaranteed.
The suction bases are available in the standard colours green (40Sh-A), red (55Sh-A) and beige (70Sh-A).
• Spring characteristics:Pressure load curves for 40 Sh-ACorrection factor for 55 Sh-A = 1.9Correction factor for 70 Sh-A = 2,9
There is a possible deviation of approx. +/-20% in the above values due to production and hardness tolerances.

GMT – Special buffers
• Description of parts and functions:
GMT-special buffers are universally ideal for supporting larger and extra-heavy-duty machinery and equipment.They provide, among other things, for vibration damping in rollers, ramming equipment, stampers, vibrationgenerators and drills.
These are just a few examples together with the spring parameters.
For outer threads >= M12 the following applies: the smooth operation of a properly functioning standard nut is considered guaranteed.
