Steel Rolling Tandem Mill Motor

A steel manufacturer sent in a steel rolling tandem mill motor after the armature equalizer insulation had failed to ground due to age and time of service. The bearings, bearing journals, and bearing housings were severely damaged. A team of different Horner Divisions came together to complete this project. Machining Services did an extensive amount of machine work on the shaft and bearing housing. They also turned and undercut the armature when the rewind was completed. Fan and Fabrication manufactured new bearing seal inserts. Horner Coatings sprayed and machined the shaft and bearing housings. They also did the welding of the [...]

Compressor Room Electric Motor

A call came in late Friday from a customer planning to have their maintenance team do an onsite bearing change on a production compressor motor. We had the bearings in stock and set aside for them, however, Monday morning I received a call letting me know that they weren’t able to complete the work in house and requested Horner Field Service to come assist as soon as possible. We sent a team that morning to pull the motor and get it in to the shop for evaluation. Once onsite, they found that the compressor room is not accessible with a forklift. [...]

Lime and Stone ID Fan

A Lime and Stone Plant called in a panic that one of their Kiln ID Fans has an inboard bearing failure that caused extensive damage to the shaft. The Kiln ID Fan is a key element in this company’s production process, so they needed a quick turnaround. Our team procured the proper shaft material and Machining Services manufactured a new shaft. As a result of Horner’s great vendor relationships, Horner’s purchasing department secured new replacement bearings in record time. The fan was restored and balanced, then assembled with new shaft, bearings, RTDs and the coupling hub. The fan was delivered in [...]

Environmental Gas Company Repair

An Environmental facility on the southside of Indianapolis draws gases off the large Landfill next door. They then filter, clean and dry the gas and then sells they turn around and sell the flammable gas to Utility companies. Our first call came in to help them with a pilot bearing replacement in the bottom of a tank that holds a mixer blade in place that mixes a solution that scrubs the methane gas to make it cleaner before it is sent to their customer as fuel. Horner’s Field Service Technicians on site discovered a lot of problems going on. The pilot [...]

Cement Fan Repair

The Springfield Division received a call from a Cement Company just before the Memorial Day weekend, for help with a large 8’ diameter propeller style fan that self-destructed. The fan lost one blade and bent over 6” of the rest of the blade tips. Mark Russell and Kim Shellabarger had a meeting with the plant manager on Friday and learned that the request was for a “patch job” with no warranty, just to get them up and running until they could acquire and install a new fan. We were also informed of the high production loss per day, while this fan [...]

Cement Rock Crusher Project

Several months ago, a Cement Company became concerned about a bearing that was failing on their rock crusher. It should be noted that this customer has only one rock crusher so when it is down, production is also down. There were multiple discussions and planning meetings with the customer as well as behind the scenes as this project was pushing the limits of our equipment. Special thanks go out to the Horner team that planned this job to make it a reality: Jim Delawder, Kim Shellabarger, Dave Whited, Mark Russell and Alan Horner. We estimated a 10 day outage to remove, [...]

52 to 2 Amps 1500 HP DC Drive Project With CoolBLUE

In September Horner was called out to a rubber manufacturer in Tennessee to measure common mode currents on a 1500HP DC Drive. The drive end gearbox had just failed. It was found that they had bearing fluting that went through the DC motor into the shaft of the gearbox and into the bearing. The DC drive was connected to the gearbox and that gearbox was connected to a mixer. It mixed raw rubber for the plant.  They measured that the amps were destructive and could cause damage by bearing fluting in the future and they would have the same problem all [...]
