PROBLEM Our customer operates a relatively large, high cycle rate press that consistently “wallowed” out the key way. As often happens, this situation snowballed until the key failed and the shaft was damaged. Despite careful attention and tighter tolerances, they still found that this […]
Read MorePROBLEM The existing Ajax gear coupling could not cope with the misalignment required for this pickling line drive. The lubricant leaks out because of grease seal wear causing the coupling to fail. Because there are a number of couplings involved, this problem generated significant […]
Read MorePROBLEM Our customer operates an old slitter/rewind. As usually happens, they were pushing for more and more production. Higher speeds and increased tension resulted in excessive heat. The higher temperatures resulted in excessive brake wear. SOLUTION This is a classic situation, trying to do […]
Read MorePROBLEM During normal operation, four cast iron components ride against an unlubricated circular aluminum bronze segmented liner ring. Unfortunately, this customer was experiencing high wear resulting in undersized inner coil diameters and steps in finished coils. The liners also required frequent replacement. SOLUTION We […]
Read MorePROBLEM Starting and threading steel from a 5000 pound coil to a slitter can be very tough. Our customer had a stand with a hydraulic motor and mechanical clutch to feed the coil strip. Unfortunately, the starting shock regularly destroyed the clutch. SOLUTION We […]
Read MorePROBLEM This steel mill is currently operating a slipper spindle coupling on their large reversing roughing mill. Unfortunately, they do have a high wear rate and the associated “slapping” causes other wear and fatigue failures in the drive system. SOLUTION A more popular approach […]
Read MorePROBLEMThis Pennsylvania steel rolling operation had a midshaft spline seize. The rest of the drive was in good shape and less than a year old. There hadn’t been any serious “crashes”, so they were puzzled as to what happened. SOLUTIONWe reviewed the system and […]
Read MorePROBLEM Several of our customers complained that they could not come up with a variety of electrical wear parts for their O/H cranes. Some components couldn’t be identified, others had been obsoleted. In some instances parts were available but excessively expensive. SOLUTION We have […]
Read MorePROBLEM A local steel mill found that they were losing several hours at each roll change while disconnecting and reconnecting the universal spindle. SOLUTION We reviewed the installation and found that working out the ten bolts in tight quarters was the time consuming part […]
Read MorePROBLEM Our customer operates several old Medart straighteners which include fairly large custom fabricated universal assemblies. Over the years, the price and availability of parts for these custom assemblies had gotten worse and worse. SOLUTION We did a careful review of the application with […]
