CR MR48728 Deep Groove Ball Bearing – 48x72x12mm High Precision Industrial Roller Bearing
The CR MR48728 is a premium single-row deep groove ball bearing engineered for exceptional reliability and operational efficiency in high-demand industrial environments. Constructed from high-carbon chromium steel (AISI 52100) and precision-machined to P6 dimensional tolerance, this bearing offers superior performance in applications requiring high rotational speeds and moderate radial and axial loads. Its optimized internal geometry, coupled with a robust pressed steel cage, minimizes friction and heat generation, leading to extended service intervals and reduced maintenance costs. The MR48728 is specifically designed to handle misalignment tolerances common in typical power transmission setups while ensuring smooth, quiet operation.
Selecting the MR48728 ensures continuity of operation and reduced Total Cost of Ownership (TCO) for critical OEM and MRO applications, including electric motors, pumps, gearboxes, and materials handling equipment. CR's stringent quality control measures guarantee consistent quality and dimensional accuracy, facilitating hassle-free installation and replacement. This bearing is pre-lubricated with a premium high-temperature industrial grease, offering immediate plug-and-play capability and robust protection against contaminants. Invest in the MR48728 for proven durability and maximum lifespan in your most challenging machinery.
