特性及应用： CKF-A 为非接触楔块式单向离合器，内环旋转。*内环被设计用于单向功能，无轴承支撑。 使用时必须 安装轴承以*内环与外环的同心度。 当用于防止逆转用途时必须检查转速不可低于超越转速*低允许值，如下页规格表中。 此型号主要用于高速工况下防止逆转，亦可用于超运转速度离合器之高速超越、低速楔合 的双速驱动切 换装置。 

Characteristics and application: CKF -a is non-contact wedge type one-way clutch, the inner ring spinning.Only the inner ring is designed to one-way function, without the bearing support.Must be installed to ensure the concentricity of the inner ring and outer ring of the bearing.When used to prevent reversal use must check speed is lower than beyond its minimum value, the following pages specification table.This model is mainly used for high speed working conditions to prevent reverse, can also be used in super speed clutch of high-speed beyond, wedge double-speed drive at low speed change cutting device.
