Key Advantages
- The RE50040 Crossed Roller Bearing is a slim‐section, high-rigidity inner-ring type bearing engineered for rotary platforms that demand stable torque, compact design, and precise positioning.
- Its structure uses orthogonally arranged rollers to deliver consistent accuracy under combined loads, making it suitable for heavy-duty yet space-restricted assemblies.

RE50040 Crossed Roller Bearing – FAQ
Does the RE50040 require special mounting tools?
+
-
Not necessarily. Standard precision mounting tools are sufficient, but proper alignment and even tightening are essential to maintain internal preload and prevent distortion during installation.
Is the RE50040 compatible with standard rotary table interfaces?
+
-
Yes, the fixed outer ring and integrated mounting holes allow it to fit many heavy-load rotary platforms without complex modifications.
How critical is preload for the RE50040?
+
-
Preload directly affects stiffness, torque stability, and lifespan. Too little preload leads to micro-slip and early wear, while too much increases friction, heat, and energy loss. Factory-preloaded settings are usually best for precision platforms.
What environmental factors accelerate wear or failure?
+
-
High humidity, abrasive particles, corrosive chemicals, temperature swings, and vibration from surrounding machinery can shorten service life if not controlled.
Can shock loads damage the bearing?
+
-
Frequent or excessive impact can dent raceways or deform rollers. Applications with sudden load changes may require additional damping or buffering.
