KA075AR0 Bearing Product Overview & Core Advantages
The KA075AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional accuracy and space optimization. Engineered as a single row bearing with a 30° contact angle, it is specifically optimized to handle significant combined loads, including both radial and axial forces. Its Reali-Slim Open construction provides a compact cross-section, making it ideal for high-precision machinery where minimizing weight and space is critical without compromising performance.
KA075AR0 Bearing Model Code Explained, Specifications & Naming Convention
- KA075: Denotes the specific bearing series and bore diameter of 7.5 inches.
- A: Indicates the angular contact design with a 30° contact angle.
- R0: Signifies the Radial Internal Clearance group, which for this bearing is 0.0000 – 0.0005".
KA075AR0 Bearing Structural Features & Performance Benefits
The bearing's performance stems from its meticulous design and material selection. The single row design with a 30° contact angle provides excellent rigidity and is optimized for handling combined loads. The brass cage ensures stable operation and guides the balls effectively. Manufactured from Chrome Steel for both rings and balls, it offers high durability and wear resistance. The ABEC-1 tolerance class guarantees consistent precision, while the specified radial internal clearance ensures optimal performance under operational temperatures and loads. The open seal type allows for custom lubrication schemes tailored to specific application needs.
KA075AR0 Bearing Typical Application Areas
This thin section angular contact ball bearing is ideally suited for high-precision and compact equipment, including:
- Robotics and automation arms
- Aerospace control mechanisms and gimbals
- Medical equipment such as MRI and CT scanners
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing heads
