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 […]
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 […]
Industrial maintenance critical to keeping pieces and parts running smoothly
Is it balance or vibration issues? Balance is the uneven distribution of weight. Vibration is shaking driven by oscillation and disturbed equilibrium. Industrial preventive maintenance is critical to operations. CMT technicians can tell if it’s balance or vibration issues or something else to keep things running smoothly. Industrial rotating equipment can be several thousand horsepower […]

The hows and whys of lifting magnets
Science Lesson #1: What’s a lifting magnet and how does it work? A magnet is really just a string of wire wrapped around a magnetic core. This string of wire has resistance we call ohms that govern what current, also called amps, flows at a given voltage. All DC magnets obey Ohm’s law and most […]
Ball bearings make the world go ’round
If it’s mechanical and spins, chances are, there’s a bearing in it. Ball bearings and roller bearings are the two most common types of bearings used in industry. Bearings work by rolling between two surfaces to reduce friction. The bearings help shafts and parts rotate in motors and machinery. How to tell if a ball […]
Preventative maintenance keeps equipment healthy
Just as you should be exercising and eating healthy for long-term health, preventative maintenance on equipment is also just as important for long-term health and longevity of a plant. A broken machine is always an unwanted expense. There are costs due to unplanned downtime, lost production and the cost of repairs. A scheduled maintenance program […]
Predictive maintenance programs head off problems before they start
Stay a leg up on costly repairs with a predictive maintenance program. A predictive maintenance program can be tailored for your company to suit your needs and budget while keeping your equipment running. Predictive maintenance programs can diagnose, track, monitor and trend equipment by detecting conditions that show up before they become costly and inconvenient […]
