    • A guide bearing attachment 12 for a rotatable element 10 having at least one end 20, the rotatable element housed within a housing 46 having a substantially circular opening 48 therein, the guide bearing attachment 12 comprising a base portion 22; a projection 32 extending from the base portion 22 at a first side 25; a circular support 30 extending from a side 24 of the base portion 22 opposite the first side 25 and having at least one open end, the open end being of similar shape to, but marginally larger than, the at least one end 20; and fastening means 28, 32. In this configuration, when the rotatable element 10 is accurately positioned at a predetermined location within the housing 46, the at least one end 20 extends into, but not through, the substantially circular opening 48 and is received within the open end of the circular support 30, the circular support 30 maintaining the accurate positioning of the predetermined location by way of a secure connection formed by the fastening means 28, 32 between the base portion 22 and the housing 46.
    • 用于可旋转元件10的导向轴承附件12具有至少一个端部20,该可旋转元件容纳在其中具有基本上圆形开口48的壳体46内,导向轴承附件12包括基部22; 在第一侧25从基部22延伸的突起32; 圆形支撑件30从基部22的与第一侧25相对的侧面24延伸并且具有至少一个开口端,该开口端具有与至少一个端部20相似但稍微大于该端部20的相似形状; 和紧固装置28,32。 在这种构造中,当可旋转元件10精确地定位在壳体46内的预定位置时,至少一个端部20延伸到基本上圆形的开口48中但不穿过基本上圆形的开口48,并且被容纳在圆形支撑件的开口端内 如图30所示,圆形支撑件30通过由基部22和壳体46之间的紧固装置28,32形成的牢固连接来保持预定位置的精确定位。
