High Load Capacity Flange Mount Rubber Shock Isolator for Marine Diesel Engine Vibration Isolation
Product Details
High Load Capacity Rubber Shock Isolator
,Flange Mount Rubber Isolator
,Marine Diesel Engine Mount
This high load capacity flange mount rubber shock isolator is engineered for marine diesel engines, where vibration, weight, and corrosion all arrive at once. A broad flange base spreads the load across the engine bedplate, while the heavy-rated rubber body absorbs the torque reaction and idle shake that a marine diesel engine generates. The flange mount rubber isolator keeps the engine seated firmly, protects gearbox couplings, and reduces the low-frequency vibration that can fatigue hull structures and nearby pipework.
The rubber compound is set at 60 Shore A hardness, a level chosen so the isolator carries high static load without collapsing yet still deflects enough to isolate engine vibration. The steel flange is treated for corrosion resistance and salt spray tested, so the flange mount rubber shock isolator suits engine rooms with high humidity and salt-laden air. Both compression and shear directions are controlled, which means warm idling and full-load running are both handled smoothly by the same mount.
Marine engineers rely on a flange mount rubber isolator because it can be bolted flat to a bedplate and shimmed for alignment, then left alone for long service intervals. This high load capacity rubber shock isolator is equally at home on auxiliary generator sets, deck machinery, and industrial diesel packages. With a documented load capacity, a defined hardness, and a corrosion-resistant flange, it gives naval architects and maintenance crews a repeatable way to isolate heavy diesel equipment without adding complex hardware.

Q: Is this mount suitable for a main engine?
A: The flange mount rubber shock isolator is rated for up to 900 kg per unit, so pairs or sets are commonly used on marine diesel engines and generator sets. Confirm total engine weight with our team and request a quotation.
Q: How does it resist corrosion at sea?
A: The steel flange carries a salt spray tested coating and the natural rubber resists aging and moisture, so the marine diesel engine mount stays serviceable in humid engine rooms.
Q: Why 60 Shore A hardness for marine use?
A: The 60 Shore A hardness keeps the high load capacity rubber shock isolator firm under heavy load while still deflecting to isolate engine vibration.
Q: Can the flange be customised?
A: Yes. We can match the flange bolt pattern and bolt size to your bedplate drawing so the flange mount rubber isolator drops straight in.
