摘要：
A roller for use in a roller guide for sliding elevator doors may include a resilient element for effecting quieter elevator operation. The resilient element may form a roller body with a bowl shaped annular casing of sheet steel to run along a carrier section including a preferably greased rail running surface. The roller body may be dimensioned such that the spring effect of the resilient element is stressed only within the elastic range or limit of the sheet steel. To obtain optimum spring effect, a radius of the rail running surface may be slightly greater than a radius of the roller body. Also, the roller body may include an open side.
