BOWER 5214 MA EL Double Row Angular Contact Bearing - 70mm Bore | High Precision Brass Cage
The BOWER 5214 MA EL is a high-performance double row angular contact ball bearing engineered for demanding industrial environments requiring robust rigidity and high-speed stability. This design inherently accommodates both significant radial loads and bi-directional axial loads, making it superior to single-row bearings where shaft deflection control is critical. The 'MA' designation signifies a high-strength, machined brass cage, which offers superior resistance to inertia, heat, and vibration compared to standard pressed steel or polymeric cages. Constructed from hardened high-carbon chrome steel (SAE 52100), the 5214 MA EL features a standard 30-degree contact angle, optimizing load distribution and ensuring low running noise even under continuous high-duty cycles.
Designed specifically for mission-critical machinery such as industrial compressors, multi-stage pumps, high-precision gearboxes, and machine tool spindles, this bearing ensures maximum operational lifespan and reduced total cost of ownership. The double-row configuration provides an optimized mounting solution, simplifying the setup while delivering the performance equivalent of two single angular contact bearings mounted face-to-face. Its precision manufacture and robust cage design translate directly into decreased maintenance downtime and increased equipment reliability, positioning the Bower 5214 MA EL as the premier choice for OEM replacement or heavy-duty upgrades where performance and endurance cannot be compromised.
Key Features
Double Row design provides extreme axial and radial rigidity.
Machined Brass Cage (MA) allows for reliable operation at higher speeds and temperatures.
Excellent capacity for accommodating combined (radial and axial) loads simultaneously.
Self-retaining unit simplifies installation compared to using matched single-row sets.
Suitable for applications requiring precise shaft guiding and minimal run-out (e.g., machine spindles).
