MR 1315 ZZ Precision Deep Groove Ball Bearing | 15x42x13mm Double Shielded Steel | High Speed
The MRC MR 1315 ZZ bearing is engineered for high-precision, medium-load applications requiring a compact, extra-light cross-section. Featuring a bore diameter (d) of 15mm and an outer diameter (D) of 42mm, this deep groove ball bearing utilizes the highly versatile 13 series structure, ensuring optimal performance in tight mechanical envelopes. The integral 'ZZ' designation denotes two non-contacting metal shields, factory-set with premium lithium-based grease, protecting the raceways from solid contaminants while retaining lubricant. Constructed from high-quality through-hardened chrome steel (SAE 52100), the MR 1315 ZZ provides exceptional durability and reliable operation up to 15,000 RPM, making it ideal for electric motors, gearboxes, pumps, and specialized instrumentation.
Optimized for reliability and reduced maintenance cycles, this bearing delivers superior performance longevity in demanding industrial environments. The robust design offers an excellent balance between radial and axial load capacity (Cr: 10.5 kN), surpassing standard thin-section bearings in comparable size classes. Its precise manufacturing tolerances (typically ABEC 1 / P0 or better) ensure quiet operation and minimal vibration, crucial for sensitive equipment. Choosing the MR 1315 ZZ guarantees interchangeability with global industry standards while providing a cost-effective solution without compromising the precision and resilience demanded by modern rotating machinery.
