A number of simple actions can be taken to extend the operating life of a lifting magnet. The following recommendations will help keep your magnet operating properly, avoid costly major repairs and signal if it’s time to get your magnet services by a company who is experienced in the design, rewind, manufacture and service of […]
What’s a journal bearing?
Simply put, a journal bearing is a shaft or journal rotating in a bearing. The shaft rotates in the bearing with a layer of lubricant separating the two parts. Because journal bearings are designed to reduce load friction, they are often used when the load is light and the motion is continuous. With a journal […]
What are centrifugal castings?
Centrifugal castings are made when a mold is continuously rotated at high speed while molten metal is poured in. The molten metal in a centrifugal casting is thrown toward the inside of the mold wall from the g forces inside. The molten metal solidifies after cooling. After cooling, any impurities can be machined away that […]
How do you make a Babbitt bearing?
Babbitt bearings are made in a few simple steps: 1. Bearing shells are restored by melting out the original Babbitt material. The grit is blasted from the shells. The bearing shells are inspected and immersed in a 100% molten tin bath to assure a good bond for the new Babbitt. 2. The prepared shell is […]
Babbitt bearings important to heavy industry
Babbitt bearings are integral to all heavy industrial machinery. Babbitt bearings are sleeve bearings made of certain types of alloys, which are melted down and cast to produce the bearing surface. Babbitt bearings are used for high speed, rotating equipment, such as compressors, turbines, electric motors, large power generators (like those in power plants). The […]

Remanufactured or new: lifting magnets attract industry
A lifting magnet is an electromagnet that can pick up or lift metal objects. A lifting magnet has magnetic properties in its electrified coil and is normally attached to a crane. The crane then positions the magnet above the objects and the magnet is energized. Lifting magnets vary in size. Some can be as big as […]
Dynamic balancing: important part of repair jobs
Dynamic balancing is simply the practice of spinning a rotating apparatus, such as a drive shaft or armature at a high rate of speed in a balancing machine. Vibration is reduced by subtracting or adding weight. A balancing machine is outfitted with sensors, and once a rotating piece has been brought up to the pre-determined […]
