Selection guides and application insights for deep groove and crossed roller bearings — written by a manufacturer, for engineers who need answers.
High Temperature Bearings. What Changes in the Heat
Heat closes the running clearance, ages the grease and softens the cage. A zone by zone walkthrough of what changes in a bearing and what to order instead.
What Is the Ball Bearing’s Potential and What Sets the Limit
What is the ball bearing's potential? The same 20mm bore spans 3.49 kN to 16.0 kN of rating, and the ceiling moves with the series, cage, seal and steel.
How to Choose Shaft and Housing Fits for Bearings
Shaft and housing fits decide whether a bearing runs for years or fails in months. Match the fit to load and rotation with this practical guide.
Bearing Internal Clearance Explained C2 CN C3 and C4
Bearing internal clearance decides how hot a bearing runs, how long it lasts, and how quiet it is. See how C2, CN, C3 and C4 differ.
Bearings for Warehouse Automation and AMR Fleets
Bearings for warehouse automation fail on duty cycle, not on load rating. See which type belongs in drive wheels, lift masts, sorters and arms.
Why Electric Motor Bearings Overheat and How to Stop It
Electric motor bearings that run hot are a symptom, not the fault. Work through these six causes in order before you replace another bearing.
How Custom Bearing Manufacturing Works From Drawing to Delivery
Custom bearing manufacturing runs through eight stages from drawing to shipment. Here is what happens at each stage, and what we need from you to start.
Sealed Crossed Roller Bearings for Collaborative Robots
Sealed crossed roller bearings for cobots: matching the seal to the environment while keeping breakaway torque and factory preload intact.
Crossed Roller Bearing Backlash and Factory Preload in Robot Joints
Where backlash comes from in a robot joint, how each source costs repeatability, and how factory preload in RAU integrated-ring bearings removes it.
Custom Crossed Roller Bearings. What Robot OEMs Specify
Custom crossed roller bearings start with a drawing. How robot OEMs specify bore, OD, tolerances, preload, and inspection, and where specs go wrong.
