K14008AR0 Bearing Product Overview & Core Advantages
The K14008AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric series of thin section bearings. Engineered for applications requiring a compact cross-section and high precision, this bearing excels at supporting combined loads (simultaneous radial and axial loads). Its 30° contact angle is optimized for significant axial load capacity in one direction. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in high-accuracy systems where space and weight are critical constraints.
K14008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Identifies the bearing as part of the Reali-Slim metric series with specific boundary dimensions. |
| 14008 | Specifies the bore diameter (140 mm) and cross-section profile. |
| A | Denotes a 30° contact angle, optimizing the bearing for high axial load capacity. |
| R0 | Specifies a standard radial internal clearance (0.0000 – 0.0005"). |
K14008AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design & High Rigidity: The single row construction with a minimal cross-section (8 mm width) saves space and weight while the chrome steel rings and precise geometry provide high rigidity for accurate positioning.
- Superior Load Capacity: The 30° contact angle enables the bearing to handle significant axial static loads (3415 lbf) in addition to its radial dynamic load rating (1418 lbf), making it ideal for combined load applications.
- Precision & Durability: The ABEC-1 tolerance class ensures consistent running accuracy. The brass cage provides excellent guidance and stability, contributing to smooth operation and extended service life.
- Wide Operating Range: With a temperature range of -30°C to 110°C and being pre-lubricated, the bearing is ready for immediate use in a variety of industrial environments.
K14008AR0 Bearing Typical Application Areas
- Robotics: Joint and actuator assemblies where compact bearings and high precision are required.
- Aerospace & Defense: Gimbals, control mechanisms, and radar systems utilizing thin section bearings.
- Medical Equipment: Precision scanners, surgical robots, and imaging devices demanding high accuracy and reliability.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and other high-precision motion control systems.
