KC140XP0 Bearing Product Overview & Core Advantages
The KC140XP0 is a high-performance thin section four-point contact ball bearing designed for applications requiring exceptional precision and load capacity within compact spaces. As an inch series bearing with a large 14-inch bore, it delivers superior performance in four-point contact configuration, enabling it to simultaneously support combined radial and axial loads from any direction. Its ABEC-1 precision and optimized chrome steel construction ensure reliable operation in demanding, high-rigidity applications where space and weight are critical constraints.

KC140XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The single-row construction with optimized raceway geometry enables the bearing to handle combined radial and axial loads efficiently, making it equivalent to a matched pair of angular contact bearings in a more compact envelope.
High Load Capacity: With a radial dynamic load rating of 2862 lbf and exceptional axial static load rating of 17280 lbf, this bearing provides robust performance in applications experiencing significant moment loads (static load moment: 49690 lbf).
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0014" to 0"), ensuring smooth operation and accurate positioning in precision machinery.
Premium Materials: Constructed from chrome steel rings and balls with a brass cage for optimal strength, corrosion resistance, and reliable performance across the operating temperature range of -30°C to 110°C.
