A large number of equipment are used in production lines of light industries such as textile, food and packaging. During mass assembly, coaxiality deviation of bearing housings frequently occurs. After long-term continuous operation, rotating shafts produce slight bending deformation under loads. Ordinary bearings cannot adapt to shaft misalignment conditions, resulting in continuous extra friction. It will not only raise operating noise, but also cause temperature rise and accelerated aging, shortening service life of mechanical components. Many light industrial production lines run nonstop all year round with frequent start and stop. Continuous slight vibration impacts bearing contact surfaces constantly. Besides, textile workshops contain fiber flyings, while food workshops have moisture and dust, which may penetrate bearings and contaminate grease. Light industrial equipment requires low operation and maintenance costs. Frequent bearing replacement will interrupt continuous production and lead to capacity loss. The market demands economical self-aligning ball bearings with reliable aligning performance, quiet operation and good resistance to lightly polluted environments.

NMT Self-Aligning Ball Bearings adopt spherical outer ring raceway and double-row ball structure. They allow limited angular deflection of shafts, effectively releasing extra stress caused by assembly error and shaft deformation and preventing local abrasion of rolling elements. Classified and precisely ground balls feature high dimensional consistency to achieve smooth rolling, reduce operating vibration and noise and satisfy low-noise production requirements of light industrial workshops. High-quality standard bearing steel and stabilizing heat treatment improve surface anti-fatigue performance to cope with alternating loads from frequent start and stop. Various sealing types are optional. Seals can block fibers, fine dust and moisture from entering raceways and slow down grease deterioration. Standardized overall dimensions deliver strong universality. Modification and replacement of new and old textile and food machinery do not require changes to equipment frames. Long service life grease lubrication can be adopted to extend maintenance intervals and reduce daily maintenance work of production lines.

Open type and double-side sealed type are available. Selection can be determined according to rotating speed, on-site dust and humidity and shaft alignment status for continuous medium and low-speed transmission mechanisms of light industry.
