Introduction

Ball transfer units

1)are omni-directional load-bearing spherical balls mounted inside a restraining fixture. They are identical in principle to a ball computer mouse upside-down, or a trackball, except there is an array of them side-by-side.

2)Typically the design involves a single large ball supported by smaller ball bearings.They are commonly used in an inverted ball up position where objects are quickly moved across an array of units, known as a ball transfer table, a type of conveyor system. This permits manual transfer to and from machines and between different sections of another conveyor system.

3)They are used in airports for luggage delivery, or in industry as part of manufacturing systems. Prior to the invention of the ball transfer unit, first patented by Autoset Production Ltd in 1958, these applications were solved by the use of inverted casters.However, casters recognize a trail, meaning that the wheels had to align before directional change could be achieved.Ball transfer units can also be used non-inverted ball down position as a type of caster, however this use is restricted by load-bearing limitations and the type of floor.

4)Manufacturers have addressed this problem with ball transfer units incorporating re-circulating ball principles, however the inverted position is still the most common application and the least problematic.

FAQ

Q: Do you make ball transfer units?

A: Yes. We offer CY, SP, KSM, NL, and KSF series with load capacities from 1kg to 500kg. Ball materials include steel, stainless steel, and nylon. Mounting options include flange, drop-in, and threaded. Please provide your load, ball material, mounting type, and quantity for a precise quotation.

Q: What is the load capacity of CY-25A?

A: CY-25A belongs to our CY standard series. Capacity depends on the exact ball diameter and mounting hole spacing. To get an accurate rating, please share the drawing or specify the variant so our engineers can confirm against the catalog specification table.

Q: Can I get a stainless steel version?

A: Yes. Full stainless steel CY series (CY-*SS) is available, for example CY-38A SS. Stainless steel suits humid, washdown, food, or chemical-exposure lines; confirm the current lead time and minimum quantity with our sales team for your variant.

Q: How do I choose between carbon steel and stainless steel ball transfer units?

A: Carbon steel is more economical and suitable for dry indoor environments. Stainless steel resists rust and is better for humid, washdown, food, or chemical exposure. For lightly loaded, scratch-sensitive applications, nylon balls are a good alternative.
