Powerdown Polyurethane Bush - Shock PinPowerdown Tuff Yello polyurethane bushes are manufactured from a proprietary urethane elastomer developed specifically to address the failure modes of both rubber and standard polyurethane shock absorber bushes. Standard rubber bushes compress, crack and extrude under the constant cyclical loading of heavy vehicle shock absorber mounting. Standard polyurethane alternatives are often too hard - transmitting vibration and wearing the mounting hardware instead of absorbing it.Tuff Yello's formulation delivers the high elasticity and return-to-shape performance of quality rubber with 3-4 times the service life. The result is a bush that absorbs shock loads correctly, maintains the shock absorber in the right mounting geometry, and does not require replacement at every shock service. 3 to 4 times longer service life than rubber equivalents under normal commercial vehicle operating conditions High memory factor - rapidly returns to original shape after each compression cycle, maintains mounting geometry Petroleum-resistant - unaffected by oils, greases, solvents and hydraulic fluids common in workshop environments Operating range -40 to +100 degrees C for Australian year-round conditions from alpine to tropical Correct bush condition prevents shock absorber misalignment that causes premature wear and failure Available in full (1-piece) and half (1/2-piece) configurations for all EB and HEB eye ring types Tuff Yello yellow colouring provides instant visual identification of Powerdown quality bushes at service Signs your shock absorber bushes need replacing: Clunking or knocking from the suspension over bumps (particularly at slow speed), visible cracking, splitting or extrusion of the bush material, the shock absorber rocking in its mount, or oil contamination of the bush material. Replace bush kits whenever replacing shock absorbers for maximum service life from the new shocks.Part number: PDB313 | Vendor: Powerdown | Australian designed for heavy commercial vehicles | Technical enquiries: 02 4949 0000 | [email protected]
