The Submersible Rubber Bush is crafted from high-performance Nitrile Rubber, designed to withstand demanding industrial applications requiring resistance to oils, fuels, and hydraulic fluids. With a static load capacity of up to 4 N/mm² and dynamic load capacity of up to 35 m/s, this rubber bush ensures reliable performance under both steady and fluctuating stresses. Featuring a hardness rating between 65-75 Shore A, the material balances flexibility and durability effectively. It exhibits superior tensile strength at 11 MPa, allowing it to endure significant stretching and stress without damage. The modulus of 3.7 MPa at 100% elongation emphasizes its elasticity under strain. The product maintains excellent elongation up to 250%, tear strength of 22 MPa for resistance against mechanical wear, and a compression set rating of 20 after 22 hours at 70°C, ensuring dimensional stability under prolonged compression and elevated temperatures. These robust mechanical and physical properties make the Submersible Rubber Bush ideal for use in submersible motor housings, pumps, and other submerged machinery components, providing effective sealing, vibration dampening, and protection against environmental factors. This specialized rubber bush is highly sought in the industrial and manufacturing sectors where component reliability under harsh operational conditions is critical.
