NB140AR0 Bearing Structural Features & Performance Benefits
Advanced Material Construction: Manufactured from chrome steel rings and balls with a brass cage, this bearing ensures optimal strength and durability. The 30° contact angle provides superior axial load capacity while maintaining excellent radial load performance.
Precision Engineering: With ABEC-1 tolerance class and tight dimensional controls (bore tolerance: -0.0014" to 0"), the NB140AR0 delivers consistent high-precision operation. The Endura-kote chromium plating offers exceptional corrosion resistance, extending service life in challenging environments.
Load Performance Characteristics: The bearing's robust design supports radial dynamic load ratings of 1767 lbf and axial static load capacity of 4670 lbf, making it suitable for applications with significant moment loads (static load moment: 19,500 lbf).
Thermal Stability: Operating temperature range of -30°C to 110°C ensures reliable performance across diverse industrial conditions, while the pre-lubrication provides immediate operational readiness.
