Engineers, fabricators, and production line builders rely on CY-series ball transfer bearing units to keep workpieces gliding effortlessly across surfaces — eliminating bottlenecks and reducing operator fatigue.\u003c\/p\u003e\n    \u003cp\u003eEach CY-series unit consists of a large load-bearing top ball seated in a housing packed with smaller recirculating support balls, all enclosed in a robust shell. Available in three materials — Carbon Steel, Nylon, and Stainless Steel — and five load-capacity sizes: CY-8H (8 mm \/ 0.31 in top ball), CY-12H (12 mm \/ 0.47 in), CY-15H (15 mm \/ 0.59 in), CY-22H (22 mm \/ 0.87 in), and CY-30H (30 mm \/ 1.18 in). Housing outer diameter ranges from approximately 17 mm to 60 mm (0.67 in – 2.36 in) depending on model.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include gravity conveyor roller tables for box and tote handling, omnidirectional transfer decks in packaging and sorting lines, and DIY workbench inserts for rotating heavy jigs or fixtures without lifting. Long-tail applications such as \"ball transfer unit for conveyor table\", \"omnidirectional roller bearing insert\", and \"CY-series ball caster for assembly line\" are all served by this versatile product family.\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 mounting holes for CY-series ball transfer units.
