Anti-vibration support --- They can protect the body's normal work and achieve a good environment, attenuating noise reduction. In radio equipment and instruments, it shields machine vibration interference, has a good buffer. Rubber Material --- Rubber vibration isolation mounts are made of softer rubber, perfect for applications requiring lighter loads where vibration reduction is essential. Geometric Design --- The simple geometric design of the rubber mounts supports dynamic performance and stability under lateral (lateral) forces. Wide Application --- Rubber insulator mounts are suitable for air compressors, diesel engines, gasoline engines, water pumps, electronic components, medical equipment, home appliances, mechanical equipment, office, aviation, construction , automotive and other applications. Package Included --- 30 x 30mm (D x H) Rubber Mount with M8 x 23mm Studs, Set of 4 Rubber Vibration Mounts. Feature 1. As a damping element for welding machine and other equipment for vibration, shock and noise control. 2. Protect the body's normal work and obtain a good environment, cushioning noise reduction and the effect is obvious. 3. In radio equipment, instruments, shield vibration interference from the machine, having a good buffer.
