curved rack and pinion,
helical rack and pinion
continuous ventilation Greenhouse rack and pinion steel pinion with copper alloy bearing
This pinion works with 30mm high rack, and is used to open and close continuous ventilation windows of greenhouses and similar building. It will be driven by a 1" steel tube.
The pinion involves mainly one gear, one galvanized sheet house, and two copper alloy bearing. Its gear is made from the technology of powder metallurgy, and is quenched. The gear has hard surface, and is strong. The gear is located in a galvanized sheet house, and is supported by two copper alloy bearings. This pinion can be easily turned, and has long life time. Its maintenance is very easy. While running, the pinion makes almost no noise.
This pinion works with rack, and is used to open and close continuous ventilation windows of greenhouses and similar buildings.
