- Cylindrical rollers arranged at 90° cross angle in V‑groove raceway
- Single bearing supports radial, axial, and moment loads simultaneously
- Compact cross‑section saves installation space
- Ultra‑High Rigidity: 3–4 times stiffer than conventional ball bearings; minimal elastic deformation under load
- Superior Rotational Accuracy: P4 precision, low runout (≤ 2 μm); ensures micron‑level positioning stability
- Space‑Saving Design: Slim profile (8 mm width) ideal for limited‑space applications
- Easy Installation: Split outer ring simplifies mounting; no extra flange required
- Smooth Operation: Roller retainers prevent friction and skewing; low torque, low noise
- Industrial Robotics: Joints, rotary bases, and manipulators
- Machine Tools: CNC rotary tables, indexing heads, and spindle units
- Medical Equipment: CT scanners, surgical robots, and imaging devices
- Semiconductor: Wafer handlers, precision inspection stages
- Aerospace: Radar antennas, satellite tracking systems
