KG042XP0 Bearing Product Overview & Core Advantages
The KG042XP0 is a thin-section four-point contact ball bearing designed for applications requiring high precision and compact design. Manufactured to inch dimensions (4.25" bore × 6.25" OD × 1" width), this single-row bearing excels in handling combined moment and axial loads simultaneously. Its Reali-Slim open construction provides maximum load capacity in minimal cross-sections, making it ideal for space-constrained applications demanding high rigidity and smooth operation.

KG042XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized raceway geometry enables the bearing to support combined moment loads (15 ft-lbf rated) along with substantial axial loads (20,520 lbf static), making it exceptionally versatile for complex loading conditions.
Thin-Section Construction: With a consistent 1" cross-section, this bearing delivers maximum performance in minimal space, providing high rigidity while reducing overall system weight and envelope size.
Premium Material Composition: Constructed from chrome steel rings and chrome steel balls with a brass cage, ensuring dimensional stability, corrosion resistance, and reliable operation across the temperature range of -30°C to 110°C.
Precision Engineering: Manufactured to ABEC-1 tolerances with tight radial internal clearance (0.0000 – 0.0005"), delivering consistent performance and smooth rotation in precision applications.
KG042XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring compact, high-capacity bearings
- Aerospace and Defense: Radar systems, satellite mechanisms, and aerospace actuators
- Medical Equipment: CT scanners, MRI machines, and surgical robotics
- Industrial Machinery: Rotary tables, indexing heads, and precision positioning equipment
