K07008AR0 Bearing Product Overview & Core Advantages
The K07008AR0 is a metric thin-section angular contact ball bearing engineered for applications demanding high precision and space-saving designs. As part of the Reali-Slim mm Metric series, this single row bearing excels in handling combined loads, specifically substantial axial loads in one direction due to its defined 30° contact angle. Its compact cross-section, with an 8mm width, makes it ideal for high-rigidity support in precision equipment where minimizing envelope dimensions is critical. The bearing comes pre-lubricated for immediate use and is manufactured to ABEC-1 precision tolerances, ensuring reliable performance and long service life.
K07008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K07008 | Denotes the bearing size series: 70mm bore, 86mm outside diameter, 8mm width. |
| A | Indicates the 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies an open (unsealed) design and standard radial internal clearance. |
K07008AR0 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row angular contact design with a 30° contact angle is engineered to support high axial static loads (2224 lbf) in one direction while simultaneously handling significant radial loads (1975 lbf static). This makes it exceptionally capable for combined load applications.
High Rigidity and Precision: Manufactured from chrome steel for both rings and balls, and featuring a durable brass cage, the bearing provides stable, high-rigidity support. The ABEC-1 tolerance class ensures precise running accuracy and consistent performance.
Compact and Lightweight Design: As a thin section bearing, it offers a significantly reduced cross-section without sacrificing performance, contributing to overall system weight reduction (0.1 kg) and compact design.
Ready-to-Install: The bearing is pre-lubricated, facilitating easy installation and immediate operation within its specified temperature range of -30°C to 110°C.
K07008AR0 Bearing Typical Application Areas
The K07008AR0 is ideally suited for a range of precision machinery and compact systems, including:
- Robotic arms and joints
- Precision rotary tables and indexing heads
- Medical and semiconductor equipment
- Aerospace actuation systems
- Optical scanning and positioning devices
