KB140XP0 Bearing Product Overview & Core Advantages
The KB140XP0 is a Four Point Contact thin section bearing designed for applications requiring high precision and space optimization. This single row ball bearing in the Reali-Slim Open series features an exceptionally slim cross-section relative to its large 14-inch bore diameter, enabling compact and lightweight designs. Its primary advantage lies in its ability to simultaneously support combined loads, including significant radial, axial, and moment loads, making it an ideal solution for demanding rotational systems.

KB140XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to handle combined radial, axial, and moment loads efficiently, often eliminating the need for complex multi-bearing arrangements and simplifying system design.
- Thin Section Construction: With a consistent cross-section of 0.3125", this bearing maximizes the available space within a housing, contributing to a compact and lightweight assembly without sacrificing performance.
- High Load Capacity: Engineered to support substantial static and dynamic loads, including a static load moment of 41,580 lbf-in, ensuring robust performance under heavy-duty conditions.
- Precision Performance: Manufactured to ABEC-1 tolerance standards, it provides reliable and repeatable rotational accuracy for smooth operation.
- Durable Material Composition: Constructed from Chrome Steel rings and balls with a Brass cage for enhanced durability and stable operation.
