ND055XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support significant moment loads (rated at 6 ft-lbf) while maintaining compact cross-section dimensions. This design provides excellent load capacity in a minimal space envelope.
Thin Section Construction: With a consistent 0.5" cross-section width, this bearing offers substantial weight savings (1.06 lbs) while maintaining structural integrity. The chrome steel rings and balls, combined with brass cage, ensure dimensional stability and reliable performance under dynamic operating conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight bore and OD tolerances (-0.0010"– 0"), this bearing delivers predictable performance and precise rotational characteristics. The controlled radial internal clearance (0.0000 – 0.0005") ensures optimal preload conditions for various application requirements.
Enhanced Surface Protection: The chromium plating coating provides superior corrosion resistance, extending service life in challenging environments while maintaining the dimensional accuracy critical for precision applications.
ND055XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, actuator mechanisms, and precision positioning systems requiring high moment load capacity
- Aerospace Systems: Control surface mechanisms, gimbal systems, and instrumentation where weight savings and reliability are critical
- Medical Equipment: CT scanners, robotic surgery systems, and diagnostic imaging equipment demanding precision motion control
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and vacuum chamber mechanisms
- Defense Systems: Turret mechanisms, targeting systems, and surveillance platforms requiring compact, high-performance bearing solutions
