KF055CP0 Bearing Product Overview & Core Advantages
The KF055CP0 is a **precision thin-section ball bearing** designed for applications requiring compact design and high performance in limited spaces. As part of the **Reali-Slim Open Bearings** series, this **single-row** construction excels in handling **radial loads** with high efficiency. Its inch-series dimensions (5.5" bore, 7" OD) and lightweight design (2.5 lbs) make it ideal for weight-sensitive and space-constrained assemblies. Manufactured to **ABEC-1 precision** standards, it offers reliable performance and consistent operation.
KF055CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF | Series identifier for Reali-Slim thin section bearings |
| 055 | Bore diameter code for 5.5 inches |
| C | Cross-section size designation |
| P | ABEC-1 precision class |
| 0 | Open design (no seals or shields) |
KF055CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The bearing features a minimal cross-section (0.75" width) relative to its diameter, providing significant space and weight savings while maintaining structural integrity.
Premium Material Construction: Manufactured from **chrome steel** for both rings and balls, with a **brass cage** for optimal strength and durability under **radial dynamic loads** up to 4,116 lbf.
Precision Engineering: The ABEC-1 tolerance class ensures consistent performance with tight dimensional control (bore tolerance: -0.0010" to 0"), making it suitable for applications requiring precise **bearing dimensions** and smooth operation.
Optimized Internal Clearance: Features a controlled **radial internal clearance** (0.0000" - 0.0005") that accommodates thermal expansion while maintaining optimal preload conditions.
KF055CP0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and satellite mechanisms where weight reduction is critical
- Robotics & Automation: Robotic joints, rotary tables, and precision positioning systems
- Medical Equipment: CT scanners, MRI machines, and surgical robot arms requiring smooth, precise rotation
- Semiconductor Manufacturing: Wafer handling equipment and precision stages
- Optical & Instrumentation: Telescope mounts, precision measuring devices, and rotary encoders
