              • Detail

              The plastic "O "belt wheel is installed at the end of the roller to separate the drive from the delivery area, eliminating the possibility of interference between the "O" belt and the delivery of goods.

              The design of precision ball bearing and plastic inner and outer cover constitute the key bearing assembly, which is not only beautiful, but also makes the roller run more quietly.

              The design of the plastic end cover at the end of the roller can prevent damage to the bearing caused by dust and splashing water to a certain extent.

              Since the groove is not rolled on the cylinder body, the cylinder body is not deformed, and the conveying will be more stable.

              Suitable temperature: -5°C ~ + 40 °C
