BOWER 5211 M EX Double Row Angular Contact Ball Bearing | 55x100x36.5mm | Precision Brass Cage for High Speed
The BOWER 5211 M EX is a premium double row angular contact ball bearing engineered for applications requiring high rigidity and superior performance under combined (radial and axial) loads. This design incorporates a 30° contact angle optimized for bidirectional axial load support, making it ideal for precision gearboxes, heavy-duty pumps, and demanding industrial compressors. The double row configuration eliminates the need for separate matching and setup common with single-row bearings, simplifying installation while maximizing running accuracy and minimizing shaft deflection. The integral design ensures precise internal preload management right out of the box.
Featuring the 'M' suffix, this bearing utilizes a robust, high-strength machined brass cage, which provides superior thermal stability and structural integrity compared to standard pressed steel cages. This attribute is critical for high-speed operation (up to 6,000 RPM) and environments where lubrication might be challenging, ensuring extended service life and reduced maintenance cycles. BOWER’s 'EX' designation indicates internal geometry optimized for enhanced load distribution and reduced friction, delivering reliability and operational longevity critical to minimizing unplanned industrial downtime.
