KC050XP4K Bearing Product Overview & Core Advantages
The KC050XP4K is a high-precision Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series. Engineered for applications demanding exceptional space and weight savings without compromising performance, this thin section bearing features a single-row design capable of simultaneously supporting combined radial and axial loads from any direction. Manufactured to ABEC 5F precision standards, it delivers high running accuracy and reliability in compact, lightweight assemblies.
KC050XP4K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC050 | Series designation for Reali-Slim® bearings with a 5" bore diameter. |
| XP | Indicates a Four Point Contact ball bearing construction. |
| 4 | Specifies the cross-section size (4 series). |
| K | Denotes a brass cage for enhanced strength and guidance at higher speeds. |
KC050XP4K Bearing Structural Features & Performance Benefits
- Four Point Contact Design: A single bearing row replaces the need for complex multi-bearing arrangements, offering a compact solution that handles combined radial, axial, and moment loads efficiently.
- High Rigidity & Load Capacity: The optimized raceway geometry provides high rigidity, with significant dynamic and static load ratings (Radial Dynamic: 1600 lbf, Axial Dynamic: 2540 lbf) for its thin cross-section.
- Precision Performance: Built to ABEC 5F tolerance class with a controlled radial internal clearance (0.0000" – 0.0005"), ensuring smooth, precise operation and low noise.
- Durable Construction: Components made from Chrome Steel (rings and balls) and a Brass cage ensure long service life and reliable performance in demanding conditions.
- Pre-lubricated: Comes lubricated from the factory for immediate installation and initial operation.
KC050XP4K Bearing Typical Application Areas
- Robotics: Rotary joints, robot arms, and gantry systems where thin section bearings save critical space and weight.
- Aerospace & Defense: Actuators, control mechanisms, and radar platforms requiring high precision and reliability.
- Medical Equipment: CT scanners, MRI machines, and surgical robots demanding smooth, precise motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
