KA050AR0 Bearing Product Overview & Core Advantages
The KA050AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim Open Bearings series, this single-row construction excels in handling combined loads with its 30° contact angle, efficiently managing both radial and axial forces. Manufactured to ABEC-1 precision standards, it offers reliable performance in compact designs where weight and cross-section are critical constraints.
KA050AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA050 | Bearing series designation for 5" bore diameter thin-section bearings |
| A | Angular contact design with 30° contact angle |
| R0 | Open construction (no seals or shields) |
KA050AR0 Bearing Structural Features & Performance Benefits
This bearing's thin-section design (0.25" width) provides significant space and weight savings while maintaining structural integrity. The 30° contact angle enables superior axial load capacity (1690 lbf static) while maintaining substantial radial load capacity (1840 lbf static). The brass cage ensures stable ball guidance and smooth operation. With precision ABEC-1 tolerances and minimal radial internal clearance (0.0000 – 0.0005"), this bearing delivers consistent performance in high-precision applications. The chrome steel construction provides excellent durability and wear resistance across a wide temperature range (-30°C to 110°C).
KA050AR0 Bearing Typical Application Areas
- Robotics and automation systems - where compact design and precision positioning are critical
- Aerospace components - requiring lightweight, high-performance bearing solutions
- Medical equipment - particularly in imaging systems and precision instruments
- Semiconductor manufacturing equipment - demanding high precision and reliability
- Optical positioning systems - requiring minimal deflection and high accuracy
- Rotary tables and indexing devices - where space constraints and precision are paramount
