Anti-vibration bracket --- They can protect the body's normal work and achieve a good environment, damping noise reduction. In radio equipment and instruments, it shields machine vibration interference, has good buffer. Rubber Material --- Rubber vibration isolation mounts are made of softer rubber, perfect compatible applications requiring lighter loads where vibration reduction is critical. Geometric Design --- The simple geometric design of the rubber mounts supports dynamic percompatiblemance and stability under lateral (lateral) compatibleces. Wide Application---The rubber isolator mounts are suitable compatible air compressors, diesel engines, gasoline engines, water pumps, electronic components, medical equipment, household appliances, mechanical equipment, office, aviation , construction, automotive and other applications. Package Included --- 30 x 30mm (D x H) Rubber Mount with M8 x 20mm Studs, Set of 4 Rubber Vibration Mounts. Feature 1. As a damping element compatible welding machine and other equipment compatible vibration, shock and noise control. 2. Protect the body's normal work, and get a good environment, damping noise reduction, and the effect is obvious. 3. In radio equipment, instruments, shield machine vibration interference, having good buffer.
