| Code Segment | Technical Meaning |
|---|---|
| ND042 | Bearing series designation for thin-section angular contact bearings |
| BR | Indicates Endura-kote chromium plating for enhanced corrosion resistance |
| 3L | Specifies lubricated configuration with premium grease |
ND042BR3L Bearing Structural Features & Performance Benefits
Thin-Section Design: With consistent 0.5" cross-section across 4.25" to 5.25" diameter range, this bearing provides space-saving solutions while maintaining structural integrity.
Premium Material Construction: Chrome steel rings and balls combined with brass cage deliver exceptional durability and stable operation under high-speed conditions.
Enhanced Load Capacity: The 30° contact angle optimizes load distribution, enabling superior axial static load rating of 4420 lbf and radial dynamic capacity of 1876 lbf.
Precision Engineering: ABEC 3F tolerance class and tight radial internal clearance (0.0000-0.0005") ensure minimal vibration and precise rotational accuracy.
Corrosion Protection: Chromium plating provides excellent surface hardness and corrosion resistance, extending service life in challenging environments.
