After continuous efforts and innovation by factory technicians, our factory has successfully developed a technology for automatic feeding of pulley core. In actual production practice, we found that errors and omissions occurred during the assembly of steel ball rollers, resulting in an increase in the defective rate. This technology developed by our factory has the effect of reducing the possibility of the ball falling off the pulley core during installation, improving the installation efficiency, and improving the yield rate, thereby further reducing product costs and increasing competitiveness. Our company's 2″-4″, 2″-7″, 3″-4″ and other roller products all involve this technology, which improves the stability of our garage door roller products and reduces production costs.
