ISOMAT IM BR ( Nitrile) Anti vibration

FD IM BR 01-07 P1

High performance shock and vibration isolation materials
ISOMAT IM BR 40, 50 70
Low frequency high performance shock and vibration
Colour: Black
Description: A specially designed highly effective low frequency shock
and vibration isolation material
Construction
Moulded from high quality Nitrile NBR rubber. Circular pockets moulded
into one side increase elasticity and create air pockets to increase isolation
efficiency. A square tread pattern moulded onto the top surface provides a
high friction grip to underside of machine base. -50 and -75 grades
generally supplied with steel interleaves.
Applications
High performance shock and vibration isolation of impact and vibration
creating machinery including: granulators, crushers, forging machines,
hydraulic and mechanical presses, diesel gensets,
Other properties
