KB040CP0 Bearing Product Overview & Core Advantages
The KB040CP0 is a Reali-Slim Open Bearing designed for applications demanding compact, lightweight solutions without compromising performance. As a single row ball bearing with an open design, it excels in handling radial loads in space-constrained assemblies. Manufactured to ABEC-1 precision tolerances and constructed from high-grade Chrome Steel, this bearing offers reliable operation and consistent performance. Its thin-section profile, combined with a substantial radial dynamic load rating of 825 lbf, makes it an ideal choice for optimizing design envelope and weight.

| B040 | Specifies bore diameter of 4 inches |
| C | Denotes cross section type (specific to Reali-Slim series) |
| P0 | Standard precision class (equivalent to ABEC-1) |
| Open | No seals or shields, allowing for custom lubrication schemes |
KB040CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a compact cross-section of only 0.3125" width, this bearing enables significant space and weight savings in precision machinery while maintaining structural integrity.
High-Quality Materials: Constructed with Chrome Steel rings, Chrome Steel balls, and a Brass cage, the bearing ensures excellent wear resistance and dimensional stability under load.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore tolerance: -0.0008" to 0") for smooth, consistent operation in precision applications.
Optimized Load Capacity: The single row design provides an impressive radial dynamic load rating of 825 lbf and static load rating of 1750 lbf despite its slim profile.
Versatile Operation: Pre-lubricated and capable of operating across a temperature range of -30°C to 110°C, suitable for various industrial environments.
KB040CP0 Bearing Typical Application Areas
Robotics & Automation: Joint actuators, rotary tables, and positioning systems where space and weight are critical factors.
