These male-thread bolt-mount units let you roll, rotate, and redirect loads effortlessly — eliminating the friction and frustration of dragging heavy panels, boxes, or assemblies across a flat surface.\u003c\/p\u003e\n\u003cp\u003eEach ball transfer unit consists of a large load-bearing ball seated in a precision-formed housing, supported by a ring of smaller recirculating steel balls that distribute weight evenly. The male-threaded bolt shank (available in M5, M6, M8, M10, and up to M40 across model sizes CY-12D through CY-40F) allows direct mounting into tapped holes or through panels with a nut. Housing diameter ranges from approximately 12 mm (0.47 in) on the CY-12D up to 40 mm (1.57 in) on the CY-40F. Bead material options include Carbon Steel, Nylon, and Stainless Steel to match your load, environment, and surface-protection requirements.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include DIY assembly tables and packing benches where workers need to slide and rotate workpieces without lifting, light conveyor roller systems for boxes and totes in garages or small warehouses, and furniture-making jigs where scratch-free multi-directional movement is critical. Long-tail applications such as \"male thread ball transfer unit for workbench\", \"M8 bolt-mount conveyor ball caster\", and \"stainless steel ball transfer unit for food-safe surfaces\" are all covered by the variant range available here.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits any panel or frame with a tapped hole or clearance hole matching the selected thread size (M5 \/ M6 \/ M8 \/ M10 and larger per model).

As a general rule, use a larger model when the load per unit exceeds what a smaller housing can safely distribute.
