Lubrication Guide for Crossed Roller Bearings

Crossed roller bearings are built for the tight spaces and heavy demands of precision rotary tables, robot joints, indexing heads, and gear reducers. Their rollers are arranged at 90 degrees to one another in a single wide raceway, and that…

Why Crossed Roller Bearings Excel in Rotary Tables

Rotary tables are among the most demanding applications in precision machining, metrology, and automated assembly. They must rotate with exceptional accuracy while simultaneously supporting axial, radial, and tilting loads. The bearing selected…

Preload and Clearance in Crossed Roller Bearings

Specifying a crossed roller bearing is rarely only a question of bore size and load rating. Two parameters, preload and clearance, determine how the bearing actually behaves once it is installed: how stiff the axis feels, how much torque the…

Crossed Roller Bearing Mounting Tips for Precision

Crossed roller bearings deliver the stiffness and rotational accuracy that machine tools, robotics, and metrology equipment demand. Yet those same qualities make them unforgiving during installation. A few micrometers of misalignment, uneven…

Choosing the Right Crossed Roller Bearing for Robots

Selecting a crossed roller bearing for a robotic application involves more than matching a part number to a mounting hole pattern. These bearings sit at the heart of robot joints, rotary actuators, and precision positioning stages, where they…

Crossed Roller vs Ball Bearings: Key Differences

When a machine's positioning accuracy depends on a single bearing interface, the choice between crossed roller bearings and ball bearings stops being a catalog detail and becomes a design decision. Both types can carry radial, axial, and moment…
