KA035AR0 Bearing Product Overview & Core Advantages
The KA035AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and precise motion control. Engineered with a 30° contact angle and single row construction, it is optimized to support significant combined loads, handling both radial and axial forces simultaneously. Its Reali-Slim open design offers a compact, lightweight solution with a large bore relative to its cross-section, making it ideal for space-constrained, high-performance systems requiring ABEC-1 precision and reliable operation.
KA035AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA035 | Indicates the specific bearing series and size (3.5" Bore, 4" OD, 0.25" Width). |
| A | Signifies the 30° contact angle, which is optimized for supporting high axial loads. |
| R0 | Denotes the standard radial internal clearance and open (unsealed) construction. |
KA035AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides high rigidity, enabling it to handle substantial combined radial and axial static loads (1310 lbf radial, 1350 lbf axial).
- Precision Performance: Manufactured to ABEC-1 tolerance class, this bearing ensures smooth, precise rotation with minimal runout, which is critical for accurate positioning.
- Optimized Material Selection: The combination of Chrome Steel rings and balls with a Brass cage offers excellent durability, corrosion resistance, and stable operation at high speeds.
- Thin-Section Design: The Reali-Slim construction minimizes weight and space requirements without compromising on load capacity or performance, contributing to overall system efficiency.
KA035AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, high-precision component with excellent load-handling capabilities. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, precision gearing systems.
- Aerospace & Defense: Gyroscopes, radar platforms, actuation systems.
- Medical Equipment: Surgical robots, MRI scanners, diagnostic instruments.
- Semiconductor Manufacturing: Wafer handling robots, precision stages.
