K13008AR0 Bearing Product Overview & Core Advantages
The K13008AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric series of thin section bearings. Engineered for applications requiring a compact design and high precision, this bearing is designed to accommodate combined loads, handling significant radial loads and axial loads in one direction. Its ABEC-1 precision class and optimized contact angle of 30° make it an ideal choice for high-reliability, space-constrained systems demanding smooth operation and precise rotational accuracy.
K13008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a specific series or design feature within the Reali-Slim metric range. |
| 13008 | Specifies the nominal bore diameter (130 mm) and cross-section. |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies a standard radial internal clearance (0.0000 – 0.0005"). |
K13008AR0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a slim width of 8 mm and a weight of only 0.17 kg, this bearing is engineered for applications where space and weight savings are critical, without compromising on load capacity.
- High Load Capacity: The 30° contact angle and robust construction using chrome steel rings and balls enable it to support high radial dynamic load ratings (1363 lbf) and significant axial static load ratings (3267 lbf).
- Precision Performance: Manufactured to ABEC-1 tolerance standards, it ensures consistent running accuracy and low vibration, which is essential for precision machinery.
- Durable Components: The brass cage provides excellent durability and guidance at moderate speeds, contributing to stable operation and extended service life.
- Pre-lubricated: Comes lubricated from the factory, ready for immediate installation and initial operation within its specified temperature range of -30°C to 110°C.
K13008AR0 Bearing Typical Application Areas
The K13008AR0 is ideally suited for a range of demanding applications across various industries, including:
- Robotics: Joint and arm articulation systems requiring compact, high-precision bearings.
- Aerospace & Defense: Actuators, control surface mechanisms, and gimbal systems.
- Medical Equipment: High-precision scanners, surgical robots, and imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and other precision motion control systems.
