KA120XP0 Bearing Product Overview & Core Advantages
The KA120XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed for applications demanding a compact cross-section and high load capacity. This inch-series bearing features a 12-inch bore in a remarkably slim 0.25-inch width profile, offering a superior solution for space-constrained designs. Its Four Point Contact construction enables it to simultaneously support combined radial and axial loads from any direction, delivering exceptional rigidity and operational precision. Manufactured to ABEC-1 tolerance standards, it is ideal for high-reliability and precision motion systems.

KA120XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The single-row construction with a brass cage allows the bearing to handle combined loads efficiently. The raceway geometry creates four points of contact between the balls and raceways, providing high moment load capacity (Static Load Moment: 22,770 lbf-in) and exceptional rigidity in a thin-section package.
High Load Capacity: Engineered for demanding applications, it offers a substantial Radial Dynamic Load Rating of 1,433 lbf and an Axial Dynamic Load Rating of 2,450 lbf, making it suitable for applications with significant radial and axial forces.
Precision & Reliability: Manufactured from Chrome Steel and built to ABEC-1 precision tolerances, the bearing ensures consistent performance and long service life. The tight radial internal clearance (0.0000 – 0.0005") contributes to precise rotational accuracy.
Versatile Operation: The open design and pre-lubrication facilitate re-lubrication for extended service, supporting a wide operating temperature range from -30°C to 110°C.
