KD110AR0 Bearing Product Overview & Core Advantages
The KD110AR0 is a high-performance thin section angular contact ball bearing designed for applications demanding exceptional precision and space optimization. Engineered as a single row, open-type bearing, it excels at handling combined loads, including significant thrust loads in one direction due to its 30° contact angle. Its Reali-Slim construction provides a large bore diameter relative to its cross-section, making it ideal for compact, weight-sensitive designs requiring high rigidity and precise rotational accuracy in accordance with ABEC-1 tolerance standards.
KD110AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Manufacturer series designation for thin-section bearings. |
| 110 | Indicates a specific cross-section and bore size combination (11" Bore). |
| A | Signifies the 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
KD110AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 30° contact angle and brass cage provides stable support, enabling the bearing to handle high radial dynamic load ratings of 3133 lbf and significant axial static load ratings of 7960 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls on bore, outside diameter, and width, ensuring consistent performance and ease of integration into precision assemblies.
- Space-Saving Design: As a Reali-Slim bearing, it offers a maximum bore diameter (11") with a minimal cross-section (0.5" width), perfect for applications where space and weight (2.05 lbs) are critical constraints.
- Durable Construction: Components made from Chrome Steel for both rings and balls provide high wear resistance and longevity, suitable for a temperature range of -30°C to 110 °C.
KD110AR0 Bearing Typical Application Areas
The KD110AR0 is ideally suited for a range of high-precision and compact machinery, including:
- Robotics: Rotary joints and arm actuators.
- Aerospace & Defense: Radar platforms, gimbal systems, and control surface actuators.
- Medical Equipment: CT scanners and surgical robot arms.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
