K34008AR0 Bearing Product Overview & Core Advantages
The K34008AR0 is a metric thin-section angular contact ball bearing designed for applications requiring high precision and compact design. As part of the Reali-Slim mm Metric Bearings series, it features a single row construction optimized to handle significant combined loads, including substantial axial loads in one direction due to its defined 30° contact angle. Its exceptionally slim 8 mm width and large 340 mm bore make it ideal for space-constrained, high-performance systems demanding high rigidity and accurate rotational motion.
K34008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a metric series thin-section bearing. |
| 34008 | Specifies the bore diameter (340 mm) and cross-section. |
| A | Denotes a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies a standard radial internal clearance and potentially other standard features for this series. |
K34008AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific construction and material selection:
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides excellent resistance to combined radial and axial loads. It offers a high axial static load rating of 6051 lbf and a radial dynamic load rating of 2366 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bore, outside diameter, and width, ensuring smooth and accurate operation in precision applications.
- Durable Material Composition: The use of Chrome Steel for rings and balls, combined with a Brass cage, ensures high strength, durability, and stable operation.
- Optimized for Thin-Section Applications: With a minimal cross-section (8 mm width), it provides a large diameter in a compact envelope, maximizing design space while maintaining performance.
K34008AR0 Bearing Typical Application Areas
The K34008AR0 is engineered for use in a variety of demanding sectors where a large bore, slim profile, and high load capacity are critical. Key applications include:
- Robotics: Rotary joints and arm assemblies.
- Aerospace: Actuation systems, control surface mechanisms.
- Medical Equipment: High-precision imaging devices (e.g., CT scanners, MRI components).
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables and indexing mechanisms.
