KD047CP0 Bearing Product Overview & Core Advantages
The KD047CP0 is a thin-section open bearing designed for applications requiring compact design and high radial load capacity. As part of the Reali-Slim® series, this single-row ball bearing features an open construction without seals, enabling direct lubrication access and optimal performance in precision assemblies. Its inch-dimension design (4.75" bore × 5.75" OD × 0.5" width) provides significant space and weight savings while maintaining robust radial dynamic load capacity of 1892 lbf. The bearing's ABEC-1 precision tolerance and controlled radial internal clearance ensure reliable operation in applications demanding dimensional accuracy and smooth rotational characteristics.

| Code Segment | Technical Meaning |
|---|---|
| KD047 | Bearing series designation for Reali-Slim® open type bearings |
| C | Radial internal clearance designation (C3 equivalent) |
| P0 | Normal precision grade (equivalent to ABEC-1) |
KD047CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent 0.5" cross-section regardless of bore size, this bearing enables compact machinery design and significant weight reduction (0.94 lbs) while maintaining structural integrity.
Premium Material Construction: Manufactured from chrome steel rings and balls with brass cage, the bearing delivers excellent durability and consistent performance across the operating temperature range of -30°C to 110°C.
Optimized Load Capacity: The single-row deep groove geometry provides exceptional radial load handling with a dynamic rating of 1892 lbf and static rating of 3530 lbf, suitable for moderate to heavy radial loading conditions.
Precision Engineering: Featuring ABEC-1 tolerance class and controlled radial internal clearance (0.0000 – 0.0005"), the bearing ensures smooth operation and minimal vibration in precision applications.
Open Design Advantage: The unsealed construction allows for custom lubrication strategies and easy maintenance access, while the ROHS compliance ensures environmental responsibility.
