KC047XP0 Bearing Product Overview & Core Advantages

The KC047XP0 is a high-performance thin section bearing designed for applications where space and weight are critical constraints. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial loads and axial loads from both directions. Its inch dimensions (4.75" bore, 5.5" OD) and exceptionally slim 0.375" cross-section make it an ideal solution for compact, high-precision mechanisms. Manufactured to ABEC-1 precision tolerances, this bearing offers reliable performance and high rigidity in a minimal envelope.

KC047XP0 Bearing Model Code Explained, Specifications & Naming Convention

Code Segment Technical Meaning Significance
KC047 Bore Size Code (4.75") Specifies the large bore diameter in inches, characteristic of thin section bearings.
XP0 Cross-Section & Design Code Indicates the "X" cross-section series (0.375" width) and "P0" designation for standard radial internal clearance and open, non-sealed construction.

KC047XP0 Bearing Structural Features & Performance Benefits

Four Point Contact Design: The single-row bearing geometry allows the balls to make contact with the raceways at four points. This unique structure enables the KC047XP0 to efficiently support combined radial and axial loads in a very compact space, eliminating the need for complex bearing arrangements.

High Rigidity & Load Capacity: Despite its thin section, the use of Chrome Steel for both rings and balls, combined with the robust Brass cage, provides exceptional structural integrity. It offers a substantial dynamic load rating of 1556 lbf (radial) and 2460 lbf (axial), making it suitable for applications with significant moment loads.

Precision & Smooth Operation: Built to ABEC-1 tolerance class with a controlled radial internal clearance, this bearing ensures smooth, low-friction rotation, which is critical for precision positioning and motion control systems.

Standard Lubrication & Versatility: The bearing comes pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C, offering broad application flexibility.

KC047XP0 Bearing Typical Application Areas

The KC047XP0 thin section bearing is engineered for high-performance applications where a large diameter must be accommodated in a very slim design envelope. Key industries and equipment include:

  • Robotics: Joints, rotary actuators, and gearing systems.
  • Aerospace & Defense: Radar platforms, gimbal systems, and control surface actuators.
  • Medical Equipment: CT and MRI scanner gantries, surgical robots.
  • Semiconductor Manufacturing: Wafer handling robots and precision stages.
  • Optical and Instrumentation Systems: Rotary tables and precision positioning devices.
