KA080XP4 Bearing Product Overview & Core Advantages
The KA080XP4 is a precision-engineered Four Point Contact Ball Bearing designed for applications requiring exceptional space optimization and high load capacity. As part of the Reali-Slim Open Bearings series with an inch system of measurement, this single-row bearing features an ultra-thin cross-section, making it ideal for compact assemblies where weight and space are critical constraints. Its Four Point Contact design enables it to simultaneously support significant radial loads, axial loads in both directions, and moment loads, delivering high rigidity and rotational accuracy. Manufactured to ABEC 5F tolerance standards, it ensures reliable performance in high-precision and demanding operational environments.

KA080XP4 Bearing Structural Features & Performance Benefits
Ultra-Thin Section Design: With a width of only 0.25 inches and a slim cross-section, this bearing provides maximum space savings and weight reduction (0.38 lbs) without compromising strength, enabling compact and lightweight machinery design.
High Load Capacity & Rigidity: The Four Point Contact geometry allows the bearing to handle combined radial dynamic load rating of 1131 lbf, axial dynamic load rating of 1890 lbf, and a dynamic load moment of 3499 lbf. This design delivers high rigidity and stability under complex loading conditions.
Precision Engineering: Manufactured to ABEC 5F tolerance class with tight dimensional control (bore/OD tolerance: -0.0012" to 0") and minimal radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise operation and minimal runout.
Durable Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage provide excellent wear resistance, dimensional stability, and reliable performance across a wide temperature range (-30°C to 110°C).
Open Design & Lubrication: The open seal type facilitates easy relubrication and is supplied pre-lubricated, supporting efficient operation and extended service life in appropriate environments.
KA080XP4 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning stages requiring high moment capacity and compact design.
- Aerospace and Defense: Guidance systems, radar platforms, and actuation mechanisms where weight savings and reliability are critical.
- Medical Equipment: CT scanners, MRI systems, and surgical robots demanding high precision and smooth motion.
- Machine Tools and Indexing Tables: Rotary tables, CNC rotary axes, and precision spindles requiring high rigidity and accuracy.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where cleanliness, precision, and thin sections are essential.
