Introduction A slewing bearing — also called a slewing ring or turntable bearing — is a large-diameter rolling-element bearing capable of handling simultaneous axial, radial, and moment loads. You’ll find them in excavators, tower cranes, wind turbine yaw systems, radar antennas, and tunnel boring machines. Selecting the wrong slewing bearing leads to premature failure, costly […]

Introduction For applications where quiet operation is critical — electric motors for HVAC, office equipment, medical devices, and household appliances — bearing noise is a key selection parameter. But “quiet” isn’t a specification — you need to specify the right noise grade and vibration class according to recognized standards. This guide explains the ABEC, JIS,

Introduction Under-lubricated bearings run dry and fail. Over-lubricated bearings overheat, blow seals, and contaminate the product. Getting the interval and quantity right is the single highest-impact maintenance practice for extending bearing service life. This guide provides the formulas, tables, and rules of thumb that maintenance teams and reliability engineers use to build lubrication schedules that

Introduction The deep groove ball bearing is the most widely used rolling bearing in the world — from electric motors to bicycle hubs, from washing machines to industrial gearboxes. But within the category, there are distinct types differentiated by sealing and shielding configuration. Choosing the right type is crucial: an open bearing in a dusty

Introduction A pillow block bearing — also called a plumber block or mounted bearing — is a self-contained bearing unit that bolts directly to a machine frame or foundation. The bearing is pre-assembled inside a cast iron or pressed steel housing, ready to support a rotating shaft. While pillow blocks are designed for simplicity, incorrect
