DESCRIPTION
V118-MG and V318 mounts have cast iron cover and base with 4 mountings holes in the base and a
central tapped hole in the cover.
The resilient elements are dtainless steel wire mesh cushions :

V118-MG and V318 have two cushions;
V118-DG and V318-D have three cushions.
APPLICATIONS
This series of mounts have a natural frequency between 18 and 25 Hz and can be used for mounting :
heavy machinery (grinders, crushers, inclined presses, eccentric presses, printing presses, textile
machines).
n
rotating machines (motors, generator sets, pumps, etc), which rotate at more than 2000 rpm for
V118-DG and V318-D and up to 2500 rpm for V118-MG and V318.
n
gantry cranes (structure, cabs, equipment).
n
The isometric stiffness characteristics and anti-rebound metal cushions of these suspensions makes
them suitable for suspending engines on ships, vehicles, etc.
As they can withstand temperatures between - 70°C and + 300°C, they can also be used for
mounting exhaust pipes.
