Originally designed for ship engines, the compact and compact installation is simple and straightforward. Its design contains control performance that limits excessive rebound impacts under impact. The upper metal cover can prevent oil pollution, effective protection of the rubber part from corrosion, different specifications and different rubber hardness, enough to meet a single meeting point load 32-3000KG, so that the inherent flat rate dropped below 8HZ, fully realize the anti-vibration drop noise.
