Ball retainers are circular assemblies that hold steel balls at evenly spaced positions within a metal or plastic cage. Different sizes, ball specifications and structures can be supplied according to samples or confirmed requirements for bicycles, electric bicycles and other light-duty rotational components.
Also known as a caged ball bearing or ball bearing retainer, this assembly keeps steel balls evenly separated for smooth rotational movement.
Ball retainers consist of steel balls held at fixed intervals in a circular metal or plastic cage. The cage helps maintain ball spacing and keeps the balls together during installation and operation.
They are commonly used in bicycles, electric bicycles and other light-duty rotational components. Retainer size, ball specification, ball quantity, cage material and structure can be supplied according to samples, drawings or confirmed matching requirements.
