Description
M/31121 Norgren Inflatable Rubber Air Bag 12"X1 Single Convoluted Type Air Spring
The GUOMAT 1B12X1T is a single convoluted type industrial air spring designed as a replacement solution for the Norgren M/31121. With a 12-inch nominal diameter, this inflatable rubber air bag provides reliable pneumatic cushioning, vibration isolation, height adjustment, and load support for industrial equipment.
Manufactured with a durable rubber air bellow and reinforced steel components, the GUOMAT air spring is suitable for applications where smooth movement, vibration reduction, and stable load support are required. Its flexible convoluted structure allows the air spring to absorb mechanical vibration and shock while maintaining consistent performance under changing loads.
