ML2214 Plastic Steel Single Chain Roller

  • Hotline: +86 0572-2561676
  • Detail

Compared with the traditional steel sprocket wheel, the high-performance polyamide sprocket wheel is used as the transmission element, and the operating noise is lower.

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.

Usually the weight of goods suitable for transport does not exceed 150kg.

Applicable temperature: -5°C~ + 40°C
