NTN R 14 ZZ HA 1 Deep Groove Ball Bearing - 7/8 Inch Bore, High Accuracy (HA1), Double Shielded
The NTN R 14 ZZ HA 1 is a premium, single-row deep groove ball bearing engineered for high-precision applications requiring an inch-series fit. This specific model features a 7/8 inch (22.225 mm) bore, a 1 1/4 inch (31.750 mm) outer diameter, and a width of 5/16 inch (7.938 mm). The designation 'ZZ' indicates two non-contact metal shields, providing robust protection against dust and contaminants while retaining factory lubrication, making it virtually maintenance-free. The 'HA 1' suffix denotes a special high-accuracy variant, ensuring exceptional rotational quality, reduced vibration, and suitability for higher running speeds than standard commercial grade bearings. Constructed from high-quality bearing steel, this NTN unit delivers the reliability and performance demanded by sophisticated machinery.
Designed for environments where metric equivalents are impractical, the R 14 ZZ HA 1 is ideal for precision motors, high-speed spindles, industrial printers, robotics, and medical devices. Its optimized internal geometry ensures efficient load distribution, handling moderate radial and axial loads with superior smoothness. Choosing this NTN high-accuracy bearing minimizes downtime and improves system efficiency across critical automation platforms. We recommend this product for engineering teams seeking uncompromising performance in inch-based mechanisms.
