JZP-2.0B Rubber Shock Absorber The JZP-2.0B is an assembled rubber shock absorber in the JZP-B series produced by Xi'an Hoan. A resilient rubber element is bonded between metal fittings, absorbing shock and damping vibration before it travels into floors, frames or housings. Typical mounting points include automobiles, machinery and engines, where the isolator reduces transmitted vibration and structure-borne noise.
