K10008AR0 Bearing Product Overview & Core Advantages
The K10008AR0 is a metric thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim series, it features a single-row design with a 30° contact angle, enabling it to efficiently support combined loads—significant radial loads alongside substantial axial loads in one direction. Its compact cross-section (8mm width) combined with a 100mm bore makes it ideal for high-precision machinery where minimizing weight and space is critical without sacrificing performance. Manufactured to ABEC-1 precision tolerance, it ensures reliable operation in demanding environments.
K10008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a metric series thin-section bearing. |
| 10008 | Specifies the bore diameter (100mm) and cross-section series. |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies a standard radial internal clearance (0.0000 – 0.0005"). |
K10008AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The single-row angular contact construction with a 30° contact angle provides excellent stiffness and capacity for combined radial and axial loads. The compact 8mm width and large 100mm bore maximize the available design space in lightweight assemblies.
High-Precision Components: Manufactured from chrome steel for both rings and balls, and featuring a brass cage, the bearing ensures smooth operation, minimal vibration, and extended service life under dynamic and static loads (Radial Dynamic: 1175 lbf, Axial Static: 2771 lbf).
Precision & Reliability: Built to ABEC-1 tolerance class with a controlled radial internal clearance, it guarantees consistent performance and high running accuracy. The open seal type allows for custom lubrication solutions tailored to specific operational needs across a temperature range of -30°C to 110°C.
K10008AR0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, actuator arms, and precision positioning systems.
- Aerospace & Defense: Guidance systems, radar platforms, and instrumentation where weight and precision are critical.
- Medical Equipment: Imaging devices (CT/MRI scanners), surgical robots, and high-speed dental handpieces.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and other cleanroom machinery.
- Optical and Instrumentation Systems: Telescope mounts, rotary tables, and measuring devices requiring high axial stiffness.
