N/A
Wear of CON-SLIDE bearings utilized in thermal expansion applications designed under the guidelines presented herein is negligible.CON-SERV Inc has independent laboratory tests available to certify to the performance of their bearings in cold weather climates. The tests were conducted per the original Alyeska Pipeline specification. Thermal cycling from -70°F to +100°F was performed on both CSA and CSB CON-SLIDE bearings. They proved to perform excellently.

N/A
The bearing system consists of an upper element faced with stainless steel and a lower element faced with a filled PTFE. The stainless steel shall be no less than 20 gauge A210 Type 304 having a surface finish of less than 20 microinches RMS on the side in contact with the CSB. The stainless steel shall be epoxy bonded in the center as well as TIG stitch welded or spot welded around the periphery. The CSB is a nominal 1/16 inch glass-filled virgin PTFE factory bonded with a tested epoxy to a steel back-up plate. The bonding shall be done in a heated bonding press under a controlled time and pressure. The coefficient of friction shall average 0.05 under a compressive load ol 2000 psi. The compressive creep shall be a maximum of 2% at 2000 psi and 70°F.The elements shall be flat, clean and prepared for installation in the structure. Slots and holes if required shall be fabricated in the bearing manufacturer's plant. |
N/A
A CON-SLIDE set usually consists of the large pad or element being the upper unit over the smaller lower pad, thus eliminating the possibility of accumulating dirt or contaminants on the interface. The bearings will function with a larger lower pad, how ever. The PTFE surfaces of the bearings shall be maintained clean and free from grit, dirt or grease. Bearing elements with slots or holes should be welded in place for location. The hearing slide surfaces must be protected during welding and maintained clean and free from foreign matter. The surface (if PTFE) must not be exposed to the direct rays of sunlight. Keep the PTFE surfaces covered. Remove vinyl masking from stainless steel slide surfaces before final placement in the structure. Do not scratch or mar surfaces. |
