KC042CP0 Bearing Structural Features & Performance Benefits
- Thin-Section Design: With a consistent 0.375" cross-section across various bore sizes, this bearing enables significant space and weight reduction in machinery design without compromising structural integrity.
- High Load Capacity: The single-row deep groove raceway and chrome steel construction provide excellent radial load capacity (1108 lbf dynamic / 2370 lbf static), ensuring durability in demanding applications.
- Precision Performance: Manufactured to ABEC-1 tolerances with tight dimensional controls (bore/OD tolerance: -0.0008" to 0"), delivering consistent running accuracy and smooth operation.
- Optimized Cage Design: The brass cage ensures stable ball guidance, reduced friction, and enhanced operational reliability at moderate to high speeds.
- Flexible Lubrication: The open design permits application-specific lubrication selection, optimizing performance for particular operating conditions and temperature ranges (-30°C to 110°C).
KC042CP0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, positioning tables, and manipulator arms where compact bearing dimensions and precision are critical.
- Aerospace & Defense: Guidance systems, radar platforms, and optical instruments requiring lightweight components and reliable performance.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices demanding high precision and smooth motion control.
- Semiconductor Manufacturing: Wafer handling equipment and precision stages where thin-section bearings enable space-efficient designs.
- Industrial Machinery: Rotary indexing tables, packaging equipment, and textile machinery benefiting from the bearing's radial load capacity and compact profile.
