Polymax KMR Machinery Mount

The KMR mount was originally designed for mounting marine engines; therefore they can be used for many mobile and static applications.

Features include built in failsafe, a limiter for shock loads, and relatively high deflection for this type of mount isolating frequencies as low as 8Hz.

Forces from propeller thrust are accommodated in the design, however be aware that the maximum loads are reduced in marine applications, see table below.
