Our ball transfer units are designed for omnidirectional, smooth movement of loads across flat surfaces. Featuring a precision ball (steel or nylon) housed in a zinc-plated steel casing, these units enable 360° rolling with minimal friction, making them ideal for material handling, conveyor systems, and equipment positioning.
Omnidirectional mobility for effortless load repositioning
Zow rolling resistance to reduce effort and surface abrasion
Flange-mount design for quick, secure installation
Choice of steel/ stainless steel or nylon balls to suit different environments
Durable zinc-plated housing for corrosion resistance and long service life
Material Handling & Logistics: Conveyor lines, sorting systems, and warehouse shelving for smooth load transfer
Industrial Machinery: Machine tools, test equipment, and mold handling for flexible positioning
Furniture & Commercial Equipment: Display racks, workstations, and medical devices for quiet, easy movement
Specialized Industries: Food processing (stainless steel balls), electronics (anti-static nylon balls), and automotive manufacturing
Shandong Guanbei Bearing Technology Co., Ltd. manufactures CY-A flange ball transfer units in Linqing, Shandong — China's bearing capital. With over 20 years of production experience, we supply ball transfer units to customers in Germany, Poland, Russia, Southeast Asia and beyond. Every unit undergoes dimensional inspection and load testing before shipment, ensuring consistent quality across bulk orders.
The CY-A flange mount design allows quick installation through four bolt holes on the flange. Simply drill matching holes on your conveyor deck or work surface, secure with bolts, and the unit is ready. For best performance, ensure the mounting surface is flat and clean. The ball protrusion height can be adjusted by adding or removing shims under the flange.
CY-A ball transfer units are pre-lubricated and sealed for typical industrial environments. For dusty or wash-down conditions, we recommend the stainless steel ball option with additional sealing. Under normal continuous operation, expect 12–24 months of service before noticeable rolling resistance increase. Relubrication fittings are available on request for heavy-duty applications.
Standard export packaging: each unit individually wrapped in anti-rust paper, packed in cartons, then palletized. Sample orders ship within 3–5 business days. Bulk production lead time is 15–25 days depending on quantity. We support sea, air and express delivery (DHL, FedEx, UPS) to any port or address worldwide.
