KG180AR0 Bearing Product Overview & Core Advantages
The KG180AR0 is a high-performance thin-section angular contact ball bearing engineered for applications demanding exceptional precision and rigidity within a compact envelope. Manufactured to inch dimensions, this single-row bearing is specifically designed to handle significant combined loads, efficiently supporting both radial and axial forces. Its optimized 30° contact angle provides superior axial load capacity and high rigidity, making it an ideal solution for high-reliability, precision rotary systems where space and weight are critical constraints.
KG180AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG | Indicates the Reali-Slim series of thin-section bearings. |
| 180 | Specifies the bore diameter in inches (18.0"). |
| A | Denotes the 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the standard radial internal clearance (0.0000 – 0.0005"). |
KG180AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides exceptional resistance to combined loads. It offers a high radial dynamic load rating of 12,898 lbf and a substantial axial static load rating of 33,200 lbf, ensuring stable performance under demanding conditions.
- Precision Engineering: Manufactured to ABEC-1 tolerance class, this bearing guarantees consistent running accuracy and smooth operation, which is critical for precision applications.
- Premium Material Construction: Components are crafted from Chrome Steel for rings and balls, and a Brass cage, ensuring high durability, wear resistance, and reliable performance across the specified temperature range of -30°C to 110°C.
- Optimized for Thin-Section Applications: With a cross-section of only 1" and a large 18" bore, this bearing maximizes space utilization and minimizes weight (13.8 lbs) without compromising on strength or performance.
KG180AR0 Bearing Typical Application Areas
This bearing is ideally suited for high-precision machinery and systems where a large diameter, compact cross-section, and high load capacity are required. Key industries and equipment include:
- Robotics: Rotary joints and actuator arms.
- Aerospace & Defense: Radar platforms, gimbal systems, and satellite communication devices.
- Medical Equipment: CT scanners and advanced imaging systems.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
