KD140AR0 Bearing Product Overview & Core Advantages
The KD140AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and accurate rotational performance. Engineered with a 30° contact angle and a single row construction, this bearing is optimized to handle significant combined loads, including high radial and axial loads simultaneously. Its inch dimensions (14" bore, 15" OD, 0.5" width) and ABEC-1 precision make it ideal for compact, weight-sensitive designs requiring high reliability and long service life in demanding industrial environments.
KD140AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Indicates the Reali-Slim thin section bearing series. |
| 140 | Specifies the bore diameter in inches (14.0"). |
| A | Denotes the 30° contact angle, optimized for combined load capacity. |
| R0 | Specifies the radial internal clearance group. |
| Open | Indicates an unsealed, open bearing design for application-specific lubrication systems. |
KD140AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specialized construction. The single row angular contact design with a 30° contact angle provides high rigidity and excellent resistance to combined loads. The use of a brass cage ensures stable operation and is suitable for high-speed applications. Manufactured from chrome steel for both rings and balls, it offers high durability and fatigue resistance. The pre-lubricated condition facilitates immediate installation and initial run-in. With a radial dynamic load rating of 3582 lbf and a static load moment of 33060 lbf, it is built to withstand rigorous operational demands while maintaining precision.
KD140AR0 Bearing Typical Application Areas
The KD140AR0 is ideally suited for a range of high-performance machinery where space, weight, and precision are critical. Key application areas include:
- Robotics and automation arms
- Aerospace control systems and actuators
- Medical imaging equipment (e.g., CT scanners, MRI gantries)
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing heads
