Engineers, maintenance technicians, and DIY fabricators who need reliable load transfer without fixed-direction constraints rely on ball transfer bearing units to keep operations moving. The CY series is engineered for exactly these demanding environments.\u003c\/p\u003e\n    \u003cp\u003eEach CY ball transfer unit features a hardened load ball seated in a housing packed with recirculating support balls, delivering smooth omnidirectional rolling. Available in three housing materials — Carbon Steel, Nylon, and Stainless Steel — and seven size designations (CY-12A through CY-38A), with housing diameters ranging from approximately 12 mm (0.47 in) to 38 mm (1.50 in). The mounting flange accepts standard bolt patterns for drop-in replacement or new installations.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include gravity conveyor tables for package sorting, CNC workpiece positioning fixtures, sheet metal handling benches, and light-duty automated assembly lines where parts must rotate or slide freely in any direction without manual repositioning.\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 standard conveyor frames and fabricated tables accepting flanged ball transfer units.
