Description
Cross roller bearing J1/J2/J3 for the Mitsubishi RV-E robot series
The cross roller bearing RV-E for axes J1, J2 and J3 is a heavy-duty precision bearing that is installed throughout the entire Mitsubishi RV-E robot series. This cross roller bearing J1 J2 J3 forms the heart of the main axes and is largely responsible for the load capacity, stiffness and repeatability of the robot. The main axis bearings of the RV-E series are among the most heavily stressed components and require prompt replacement when worn.
Technical features
- Type: cross roller bearing
- Axis positions: J1, J2, J3 (main axes)
- Compatible with: Mitsubishi RV-E robot series
- Load type: high combined radial, axial and moment loads
- Version: for main axes with maximum stiffness
- Precision class: highly accurate for industrial robot applications
Use in the RV-E series
The Mitsubishi RV-E series comprises compact vertical articulated robots that were used in assembly, material handling and machine loading. Axes J1 (base rotation), J2 (shoulder) and J3 (elbow) carry the greatest loads and are decisive for the overall kinematics of the robot. The cross roller bearings used here have to absorb extreme tilting moments and torques. A worn main axis bearing manifests itself in vibrations, noises and declining path accuracy.
Availability and notes
Mitsubishi has discontinued this series – now only available in limited quantities worldwide. Main axis bearings are particularly critical components – we recommend early stockpiling. Sold without warranty.
Alongside spare parts, ROBTEC also offers retrofit and maintenance services for your Mitsubishi robots. From bearing inspection through replacement to recalibration – all from a single source.
