After experiencing numerous axle hub failures on new production, a customer called upon VNC to help determine the root cause and solution. Although most of the bearings were badly destroyed and difficult to inspect, the forensic examination continued to point towards inadequate lubrication as the root cause of failure. During the examination the bearing fragments from the raceways and rollers consistently demonstrated severe discoloration and scoring. At such an early stage in their field life, such signs would not occur under proper lubrication conditions.

Remanufacturing can return a bearing to service in a fraction of the time it would take to obtain a new bearing, at a significant cost savings. Read the following case studies to find out how the choice of bearing remanufacturing over a new OEM replacement has helped our customers meet schedule and budget demands. Remanufacturing helps power plant avoid operating interruption Challenge: Returning a worn bearing to service on-schedule. When the lead time for replacing six worn pulverizer roll wheel bearings wouldn't meet a 1, MW coal-fired power station's schedule requirements, bearing remanufacturing was the solution, saving the company time and money.

Sep 9, Predictive Maintenance , Vibration Analysis 0 comments. Like most industrial technologies, Variable Frequency Drive VFD units have grown increasingly affordable over the past few years and have become common in many facilities to better control processes. While there are many advantages to implementing VFDs on existing equipment, there are some pitfalls as well.
To remove the bearings, two jaw pullers were used, and to replace the bearings a SURETHERM 10X induction heater with two temperature probes was used to precisely heat and demagnetize the bearings for installation. Previously a different portable induction heater had been used, but it took much too long, the heater itself got hot and it only had one temperature probe. The great advantage of the SURETHERM bearing heater is that the twin temperature probes let you precisely monitor the difference between the inner and outer race temperatures and keep that differential to a minimum in order to prevent stressing the bearing.
