KG075AR0 Bearing Product Overview & Core Advantages
The KG075AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim Open Bearings series, this single-row construction excels in handling combined loads, particularly substantial axial loads in one direction due to its specific 30° contact angle. Its inch-series dimensions (7.5" bore) and ABEC-1 precision make it ideal for compact, high-rigidity systems where accurate rotational performance is critical.
KG075AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG075 | Bore diameter designation (7.5 inches) |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance specification |
KG075AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single-row angular contact design with 30° contact angle provides exceptional stiffness and optimized load distribution. It delivers outstanding axial load capacity (19,420 lbf static) while maintaining significant radial load capability (16,110 lbf static), making it ideal for combined loading applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore tolerance: -0.0012" to 0"), ensuring consistent performance in precision applications. The minimal radial internal clearance (0.0000-0.0005") contributes to precise shaft positioning and reduced vibration.
Premium Material Construction: Features chrome steel rings and balls for durability and wear resistance, combined with a brass cage that provides excellent dimensional stability and smooth operation at various speeds.
Space-Saving Design: As a thin-section bearing with 1" width relative to its 7.5" bore, it offers significant weight savings (6.2 lbs) while maintaining structural integrity, perfect for compact machinery designs.
