KD140CP4K Bearing Structural Features & Performance Benefits
- Thin-Section Design: With a consistent cross-section of 0.5", this bearing enables significant space and weight savings in complex assemblies, contributing to overall system high rigidity and compactness.
- High Load Capacity: Despite its slim profile, it offers a substantial radial dynamic load rating of 3427 lbf and a radial static load rating of 9920 lbf, ensuring reliable performance under demanding conditions.
- Precision Engineering: The ABEC 5F tolerance and controlled radial internal clearance (0.0000 – 0.0005") result in low noise, minimal vibration, and high running accuracy, which is critical for precision applications.
- Premium Materials: Constructed from Chrome Steel rings and balls with a Brass cage, the bearing provides excellent durability, wear resistance, and stable operation across a wide temperature range from -30°C to 110°C.
KD140CP4K Bearing Typical Application Areas
This bearing is ideally suited for applications where a large diameter is required in a confined space. Key industries and equipment include:
- Robotics and automation systems (e.g., robotic arm joints)
- Aerospace and defense components (e.g., radar platforms, gimbals)
- Medical Equipment (e.g., MRI scanners, CT scanners)
- Semiconductor Manufacturing equipment
- Precision rotary tables and indexing drives
