It was a desperate situation. A critical output shaft bearing failed, bringing operations to a standstill for a commercial and industrial roofing manufacturer in Harrisburg, PA. Without a backup, their facility in Carlisle, PA, was facing a 40-week lead-time on a replacement assembly.
The customer was in a precarious position – his inability to use its extruder to mix rubber effectively shut down their entire plant. He called Applied Industrial Technologies. Applied® manager Mike Gibson understood the urgency of the situation and called Timken’s Principal Sales Representative, Mike Miller, and Principal Service Representative, Jim Mayhugh, for help.
Mike Gibson sent the bearing – a tapered double outer (TDO) with two single cones and a double cup – to Timken for assessment. They soon learned, “The bearing was history. There was nothing to save."
Further investigation showed evidence that the gearbox manufacturer may have replaced the original Timken cone spacer with one of its own. Therefore, the bearing setting may have been changed and contributed to the damaged bearing.
Meanwhile, the customer was forced to subcontract the rubber mixing to an outside company and have it trucked to the plant at great expense. In addition, many employees in the mixing department were without work due to the idle extruder.
Searching Timken's inventory, Jim located a configuration with two cones and no cups. Mike Miller found a tapered double inner bearing with a double cone and two single cups.
Once Jim received the products, he crafted a 2TSIM assembly that would meet the customer’s needs and had the gearbox built. Jim put the bearing together on the gearbox shaft and had it rushed to the customer for installation.
The extruder began turning again after just more than a week of down time. The resourceful Applied®
/Timken team delivered a tremendously efficient and valuable service to the customer in record time.
