KD040CP3 Bearing Product Overview & Core Advantages
The KD040CP3 is a high-precision thin section bearing designed for applications requiring exceptional space optimization and weight reduction. As part of the Reali-Slim Open Bearings series with a single row construction, it delivers reliable radial load capacity within an extremely compact cross-section. Manufactured to ABEC 3F precision standards and pre-lubricated, this bearing is engineered for smooth operation in precision equipment and motion control systems where minimizing envelope size is critical.
KD040CP3 Bearing Model Code Explained, Specifications & Naming Convention
- KD040: Indicates a thin-section bearing series with a 4" bore diameter.
- C: Signifies the radial internal clearance group.
- P: Denotes the specific cage design and material (Brass).
- 3: Represents the tolerance class (ABEC 3F).
KD040CP3 Bearing Structural Features & Performance Benefits
This bearing's performance stems from its optimized thin section design and material selection. The single row of balls housed within a brass cage ensures stable operation and minimal friction. The use of Chrome Steel for both rings and balls provides high durability and wear resistance. Its open construction allows for custom lubrication schemes, while the precise ABEC 3F tolerance guarantees consistent running accuracy. The compact 0.5" width and light 0.78 lbs weight make it ideal for applications where every millimeter and gram counts, without sacrificing the radial dynamic load rating of 1755 lbf.
KD040CP3 Bearing Typical Application Areas
The KD040CP3 is ideally suited for:
- Robotics and automated guided vehicles (AGVs)
- Aerospace control mechanisms and actuation systems
- Medical equipment including scanners and surgical robots
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing systems
