| P0 | Normal precision grade (equivalent to ABEC-1) |
| Open | No seals or shields, allowing maximum speed capability |
KD040CP0 Bearing Structural Features & Performance Benefits
Thin Section Design: The bearing features an exceptionally slim 0.5" width relative to its 4" bore diameter, enabling compact machine designs and weight reduction in applications where space optimization is critical.
Premium Material Construction: Utilizing chrome steel for both rings and balls ensures high durability and wear resistance, while the brass cage provides excellent stability and guidance at moderate speeds.
Precision Performance: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.0008" to 0"), ensuring consistent performance and reliable operation in precision applications.
Optimized Load Capacity: With a dynamic radial load rating of 1755 lbf and ISO radial rating of 3523 lbf, this bearing delivers reliable performance under substantial radial loads despite its thin cross-section.
Versatile Operating Range: Suitable for temperatures from -30°C to 110°C and compatible with various lubricants, providing flexibility across different operating environments.
