Heavy Duty Shaft Coupling Strategies

Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be overengineered with regard to stiffness. Keyed connections and excessively rigid coupling designs do have some under-recognized limitations— especially in large industrial, material handling, construction and mining machines.

Lubrication Considerations for Bearings

Bearings must be properly lubricated for optimized performance and long service lives, so choosing the correct lubrication is an integral consideration for engineers. AST Bearings’ tribological team has created this comprehensive whitepaper to best explain these lubrication considerations in rolling element bearings. The paper examines types of bearing lubricants (oil, grease and solid film), bearing lubrication methods, bearing lubrication shelf life, and a detailed table showing common bearing lubricants and properties.
