The main product is ball cage type, designed and developed BJ, BHJ, BJS, BC, DOJ five categories, compared to NTN, the model specification is more complete, for different fields, use conditions, almost all can choose the appropriate coupling. In the field of vehicles, unlike NTN's route to the main engine, BOYA Drive Shaft focuses on the field of special vehicles, with larger model specifications and the ability to adapt to greater torque carrying capacity, resulting in outstanding competitive advantages in the field.
In the field of metallurgy, BOYA has developed and applied high speed, heavy load, and large angle ball cage drive shafts with a comprehensive selection of models and specifications, such as BJ type drive shafts for the drive equipment of pinch rolls, deflection rolls, live sleeves, tension rolls, degreasing rolls, scrubbing rolls, sealing rolls and squeezing rolls in various production lines in ferrous metallurgy, and BHJ type drive shafts for the main drive of mills in non-ferrous metallurgy, all of which are widely used and occupy a major market share in China. The BHJ type drive shafts are widely used in the main drive of rolling mills in non-ferrous metallurgy and occupy a major market share. The ball cage type drive shafts are significantly better than the cross shaft type in terms of life, rotational accuracy, and adaptability to high speeds at approximately the same rotary diameter. Compared to long shaft drum tooth drive shafts, ball cage drive shafts can adapt to greater angles of use and impact loads; compared to short drum tooth couplings, BOYA has developed the BJS type ball cage drive shaft, which has a greater angle of application and expansion than the drum tooth type, simplifying installation and adjustment. As the ball cage technology is later than the cross shaft type and drum tooth type, the product technology is more advanced and the competitive advantage is outstanding, it is gradually expanding the application area and the market share continues to climb.
