An electric motor rewind can be done to make a motor workable again without the high cost of paying for a new motor. A motor can also be rewound in an emergency, thus minimizing a customer’s downtime. For example, if an AC motor fails, it usually means that the insulation or coils were damaged by […]
How do you safety test lifting magnets?

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 […]
