What chain is best suited for high precision conveyors that require highly accurate positioning?
Within automated manufacturing, assembly, and inspection lines there are straight line type base machines (high precision conveyor) that preserve positioning accuracy. Chains are utilized as one type of conveyance method for these applications, but with regular chains sliding wear occurs between the pin and bush, causing the chain to elongate and eventually loose its positioning accuracy. Because of this it becomes necessary to carry out frequent positioning maintenance. However, Tsubaki has solved this problem with the introduction of high precision conveyor chains. By inserting cylindrical bearings into the area between the pin and bush this area has changed from a sliding bearing to a rolling bearing, considerably lowering wear elongation and making high speed high accuracy precision positioning possible. There are 4 types of high precision conveyor chains that are differentiated by their use and level of required accuracy.
