High polymer material is lighter than steel material, thus reducing consumption for starting and braking. It has high resistance to abrasion, corrosion and rust, thus prolonging the service life of roller and reducing the workload for maintaining it. In addition small crusher, the thermoplastic material has the function of vibration absorption and then can reduce noises. The cylinder and bearing pedestal have simple structure; this avoiding the process of seam allowance of cylinder and the press forming technology can ensure dimensional accuracy and quality. The cylinder and the bearing pedestal are connected with plastic cement, which is not only easy to be assembled, but has wider adaptation ranges on temperature.

The service life of roller is mainly determined by bearing and sealing performance. For this reason, when designing bearing, deep groove ball bearing with dust cap can be used to not only ensure the cleanness inside the bearings, increase its axial carrying capacity and reducing the high frequency damage to bearing caused by axial force and high-frequency percussion, but ensure the lubrication performance of the bearings and improve the actual service life of the bearings.
