FAG 7411 B MP UA High-Precision Angular Contact Ball Bearing | 55x100x21mm | 40° Universal Paired Design
The 7411 B MP UA is a premium single-row angular contact ball bearing engineered for applications requiring high rigidity, superior speed capability, and exceptional running accuracy. This designation signifies a 40° contact angle (B) optimized for absorbing significant combined radial and axial loads, typically found in machine tool spindles, high-speed pumps, and precision gearboxes. The inner-ring guided machined brass cage (MP) ensures maximum operational stability and allows for higher limiting speeds compared to standard polyamide cages, making it ideal for continuous, demanding industrial operations. The open design facilitates optimal lubrication and inspection, ensuring extended service life under variable load conditions.
The critical 'UA' suffix denotes a universal design, meaning the bearing is manufactured with controlled axial internal clearance to be mounted immediately in duplex sets (O, X, or tandem arrangements) without requiring external shims or spacers. This simplifies installation, guarantees the correct pre-load (moderate), and maximizes system rigidity. Offering robust dynamic load capacity (Cr) of 55.5 kN, the 7411 B MP UA provides reliable performance for critical machinery where precision, thermal stability, and low noise operation are non-negotiable requirements for minimizing downtime and maximizing productivity.
