Product Overview and Core Advantages
The K11013AR0 is a metric thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim mm Metric Bearings series, this single row bearing excels in handling combined loads, particularly substantial axial loads in one direction due to its 30° contact angle. Its compact cross-section (13 mm width) with a relatively large 110 mm bore diameter makes it ideal for lightweight, high-rigidity designs in precision machinery. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance and dimensional consistency.

Structural Features and Performance Benefits
Optimized Thin-Section Design: The bearing's 13 mm width with a 110 mm bore provides exceptional space savings while maintaining structural integrity, crucial for compact machinery layouts.
Superior Load Capacity: The 30° contact angle enables excellent axial load carrying capability (Axial static load rating: 5412 lbf) while maintaining substantial radial load capacity (Radial dynamic load rating: 2339 lbf). This makes it suitable for applications experiencing significant combined loads.
Precision Construction: Manufactured from chrome steel rings and balls with a brass cage, the bearing ensures dimensional stability and reliable operation. The ABEC-1 tolerance class guarantees consistent performance in precision applications.
Optimized Internal Geometry: The precise shoulder diameters (inner ring: 119.7 mm) and controlled radial internal clearance (0.0000 – 0.0005") contribute to smooth operation and reduced vibration.
K11013AR0 Bearing Typical Application Areas
The K11013AR0 thin-section angular contact ball bearing is ideally suited for:
- Robotics and automation systems - where compact design and precise motion control are critical
- Aerospace components - including control mechanisms and instrumentation requiring lightweight, high-precision bearings
- Medical equipment - particularly in imaging systems and surgical robots demanding space optimization
- Semiconductor manufacturing equipment - for precision positioning stages and handling systems
- Optical and measuring instruments - where minimal deflection and high accuracy are paramount
