KC050AR0 Bearing Product Overview & Core Advantages
The KC050AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and precise motion control. Engineered with a single row construction and a 30° contact angle, this bearing excels at handling combined loads—simultaneously supporting substantial radial and axial forces. Its Reali-Slim open design provides a compact, lightweight solution without sacrificing performance, making it ideal for space-constrained, high-reliability systems requiring ABEC-1 precision.
KC050AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC050 | Indicates the specific bearing series and size designation for a 5" bore. |
| A | Signifies the 30° contact angle, optimized for high axial load capacity. |
| R0 | Denotes a standard radial internal clearance and open (unsealed) construction. |
KC050AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides superior stiffness, enabling it to handle high radial dynamic load ratings of 1313 lbf and axial static load ratings of 3200 lbf effectively.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls on bore diameter and outside diameter, ensuring smooth, precise operation and minimal runout.
- Optimized Material Selection: Components made from chrome steel (rings and balls) and a brass cage offer excellent durability, corrosion resistance, and stable performance across a temperature range of -30°C to 110°C.
- Space-Saving Design: With a slim width of just 0.375" and a large 5" bore diameter, this thin section bearing maximizes design flexibility in compact assemblies.
KC050AR0 Bearing Typical Application Areas
- Robotics & Automation: Precision joints, rotary actuators, and manipulator arms requiring high moment stiffness.
- Aerospace & Defense: Gimbals, radar platforms, and guidance systems where lightweight and high precision are critical.
- Medical Equipment: CT scanners, surgical robots, and imaging devices demanding smooth, accurate rotational motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that operate under combined loads.
