According to the specific requirements of automotive gearboxes, WD Bearing Group successfully developed 2 low noise products recently, 31309 and NJ309V V1.
31309 is a single row tapered roller bearing with big taper angle and NJ309V V1 is a single row full complement cylindrical roller bearing. Both of them are widely used for gearboxes and the OEM customers always request low noise and better performance for the two items. WD analyzed all the possible factors of noise, optimized internal structures, tested samples and improved the design again and again. After several months' hard working, WD can control the noise level of the two products less than 66dB. And these bearings had been supplied to OEM customers by batch orders until now. It's the essence of power and wisdom of WD technical staff and manufacturing team. And it's also one more successful case of research & development for our customers.
WD Bearing Group is always happy to work with you to research, design, develop, manufacture products, and control quality during the whole process.
