The long-life and high-sealing rollers designed and produced by Juxin Company are mainly developed for the current belt conveyor roller manufacturing accuracy is not high, the rotation resistance coefficient is too high, the running noise is large, the sealing is poor, and the design life is generally not reached. The roller adopts a fully sealed, waterproof and dustproof structure, and the bearing assembly adopts high-precision bearing chamber and special high-quality bearings for the roller. It has the advantages of exquisite structure, low noise, maintenance-free, long life (service life over 50,000 hours), and reliable performance. It is a good choice for advanced belt conveyor systems.
