WB040CP0 Bearing Structural Features & Performance Benefits
Compact Design & High Precision: With a slim cross-section (width: 0.3125") and **ABEC-1 tolerance class**, this bearing delivers precise rotational accuracy while saving space in compact assemblies. The **stainless steel cage** ensures smooth ball guidance and reduced friction.
Superior Sealing & Corrosion Resistance: The integrated seals provide effective contamination protection, while the **all-stainless steel construction** offers excellent resistance to corrosion in harsh environments. The **pre-lubricated design** ensures immediate operation and extended service life.
Optimized Load Capacity: Engineered for **radial dynamic load rating of 825 lbf** and **radial static load rating of 1750 lbf**, this bearing provides reliable performance in applications with significant radial forces. The controlled **radial internal clearance** (0.0000 – 0.0005") ensures consistent operation across temperature variations.
Wide Temperature Range: Operating effectively from **-30°C to 110°C**, this bearing maintains performance across diverse environmental conditions, making it suitable for both industrial and precision applications.
