KG120AR0 Bearing Product Overview & Core Advantages
The KG120AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. This single-row bearing is designed to handle significant combined loads, efficiently supporting both radial and axial forces in one direction. Its inch-series construction with a large 12" bore and compact 1" cross-section makes it ideal for high-rigidity support in precision equipment. Manufactured to ABEC-1 tolerance standards, it delivers reliable performance for demanding industrial applications.
KG120AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG120A | Bearing series designation for thin-section angular contact bearings |
| R0 | Radial internal clearance specification (0.0000-0.0005") |
| Open | Unsealed construction for direct lubrication access |
KG120AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: With only 1" width and large 12" bore diameter, this bearing provides maximum space savings while maintaining structural integrity for high-rigidity applications.
Superior Load Capacity: The 30° contact angle enables excellent axial load capacity (25,780 lbf static) while maintaining substantial radial load capacity (24,640 lbf static), making it ideal for combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 standards with tight dimensional tolerances (±0.0014" on diameters) ensures consistent performance in precision positioning systems.
Premium Material Construction: Chrome steel rings and balls with brass cage provide durability and smooth operation across the operating temperature range (-30°C to 110°C).
