Introduction Internal clearance is one of the most misunderstood yet critical parameters in bearing selection. Choose the wrong clearance class, and your bearing will either overheat from excessive preload or vibrate from excessive slop. This guide explains what radial internal clearance (RIC) means, what each clearance class (C2 through C5) is designed for, and how […]

Introduction 7 bearing failure types infographic: spalling, brinelling, contamination, electrical erosion, misalignment, corrosion, lubrication failure Bearing failures rarely happen in isolation. When a bearing fails prematurely — defined as failure before reaching its calculated L10 fatigue life — there’s almost always a root cause in installation, lubrication, contamination, or operating conditions. Misdiagnosing the failure mode

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 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
