A disassembly evaluation at CMT indicated the rolling element bearing failed because of service conditions. The DC roll motor and gearbox needed new shafts, bearings and gears because of improper alignment. Alignment is important in double shaft extensions. If one or both sides aren’t aligned, bearings are destroyed and shafts can twist. In addition to […]
CMT is an essential business, and we are open
Ohio has been issued a “stay-at-home” order from Governor DeWine. CMT is excluded in this order because our work on power plant operations, food manufacturers, municipalities and commercial and industrial HVAC makes us essential. Our operations have not been disrupted, and we will continue business as usual. Here at CMT, we are continuing to monitor […]
Download a free coloring book for your children
We designed a kid’s coloring book to celebrate National Skilled Trades Day on May 6th this year. Let’s celebrate early! Kids are home from school and parents are seeking fun, free resources. Download and print it here. When your child has colored it, staple it like a book. Have them read it to you or […]
Babbitt bearings can have a long life with continuous monitoring and proper lubrication
Babbitt bearings are used in critical industrial applications like turbines, large motors, fans and blowers. They can be found in power plants, on military ships and in all industrial manufacturing facilities. Babbitt bearing failure often occurs because of maintenance issues: Lubrication deficiencies, contamination, mechanical alignment or vibration issues. With monitoring and proper lubrication, Babbitt bearings […]
CMT offers industrial gearbox repairs
Many gearbox designs are splash lubricated and, because of this, some internal components that help rotational shaft speeds do not receive enough amounts of lubrication. Design, fabrication and installation of oil reservoirs containing lubricant ensures bearings will be properly lubricated while the gearbox is functioning. CMT can do all industrial gearbox repairs including gear installation, […]
On-site preventative maintenance ensures everything is working and running efficiently
Industrial preventive maintenance is critical to operation. Industrial rotating equipment can vary from a stand-alone machine to an entire process line. Each individual machine often contributes to the completed product. Preventative maintenance can be the main contributing factor to bottom line profits and prevents work stoppages. CMT technicians and tools in the field service vans […]
Two varnish processes available for motors: Dip and Bake and Vacuum Pressure Impregnation
There are two available varnish processes for electric motors: Dip and Bake immerses a motor into a tank of varnish. Vacuum Pressure Impregnation (or VPI) is a process that places the motor into a chamber with a controlled atmosphere. The dip and bake method develops a hydro static pressure that dissipates many air voids and […]
Bearing failures can be prevented with good maintenance, lubrication and analysis
Mechanical failures account for the most outages in industrial rotating machinery with a high majority being a bearing failure. Bearing failure symptoms could include: an audible noise, heat, smell, smoke or vibration. Lubrication is essential to rotating equipment longevity. There is a science to intervals, composition of lubricant and amount of lubricant installed. CMT can […]
Preventative maintenance is essential for journal bearings
Journal bearings are a housing shell or metal sleeve that allows a shaft to rotate freely inside while the assembly is structurally supported. Numerous journal bearing applications exist: Journal bearings can be used in low-speed operations (5 rpm or less) in a grease lubricated brass sleeve. Pictured is an oil ring lubricated Babbitt bearing in […]
Vacuum pressure impregnation enhances the life of electrical motor windings
Vacuum pressure impregnation, known as VPI, is a varnish process for electric motor insulation. The several-hour process begins with a prebake cycle to remove any moisture, the component is placed into the varnish chamber, a vacuum is pulled to remove air, varnish is introduced and the varnish chamber is pressurized. Computerized capacitance monitoring insures a […]
