KD080AR0 Bearing Product Overview & Core Advantages
The KD080AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding exceptional precision and space optimization. Manufactured to inch dimensions, this single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its defined 30° contact angle. Its Reali-Slim Open construction provides a superior stiffness-to-weight ratio, making it ideal for compact, high-accuracy assemblies where minimizing cross-section is critical. The bearing comes pre-lubricated for immediate use and offers reliable operation across a broad temperature range.
KD080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Manufacturer series prefix for thin-section bearings. |
| 080 | Indicates a bore diameter of 8 inches. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the internal design and standard radial internal clearance. |
KD080AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a rigid brass cage, provides exceptional resistance to combined loads, supporting significant axial and radial forces.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight bore and outside diameter tolerances, ensuring smooth, precise operation and reliable performance in high-accuracy systems.
- Space-Saving Design: As a thin section bearing with a cross-section of only 0.5", it offers a maximum load capacity within a minimal envelope, crucial for compact machinery design.
- Durable Construction: Components made from chrome steel provide high strength and wear resistance, contributing to a long service life under demanding conditions.
KD080AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a large diameter with a very slim profile and high axial stiffness, including:
- Robotics and automation arms
- Aerospace control mechanisms and gimbals
- Medical imaging equipment (e.g., CT scanners)
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing drives
