KA100AR0 Bearing Product Overview & Core Advantages
The KA100AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and accurate positioning under combined loads. Manufactured to ABEC-1 tolerance standards, this single-row bearing features a 30° contact angle, enabling it to support significant radial loads and unidirectional axial loads simultaneously. Its ultra-slim cross-section (0.25" width relative to its 10" bore) makes it an ideal solution for compact, weight-sensitive designs in high-performance machinery, offering a superior strength-to-size ratio.
KA100AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA | Indicates the specific series for Reali-Slim® Angular Contact bearings. |
| 100 | Specifies the nominal bore diameter of 10.0 inches. |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
KA100AR0 Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The single-row design with a generous contact angle provides high rigidity, supporting a radial dynamic load of 1014 lbf and a substantial axial static load of 2640 lbf. This makes it exceptionally capable of withstanding combined loading scenarios.
Precision Engineering: Constructed from chrome steel rings and balls with a brass cage, the bearing ensures smooth operation and durability. The tight bore and OD tolerances (-0.0014" to 0") guarantee precise shaft and housing fits, critical for maintaining system accuracy.
Optimized for Performance: The lubricated design and controlled radial internal clearance contribute to low running torque and stable operation. Its wide operating temperature range (-30°C to 110°C) ensures reliability in diverse environments.
KA100AR0 Bearing Typical Application Areas
- Robotics and Automation: Ideal for robot arm joints, rotary tables, and precision actuators where high rigidity and compact design are paramount.
- Aerospace and Defense: Used in gimbal systems, radar platforms, and guidance mechanisms requiring lightweight and high-precision components.
- Medical Equipment: Suitable for CT scanners, surgical robots, and imaging devices that demand smooth, precise, and reliable motion control.
- Semiconductor Manufacturing: Applied in wafer handling robots and precision stages where minimal deflection and high accuracy are critical.
