What is a Ball Transfers?
What is an Air Ball Lifter?
Ball transfer units consist of a large load-ball that sits upon small balls encapsulated in
a hemispherical cup. Ball transfers fall into two categories, Ball-up type and Ball-down
type, like a caster. Also, in some applications, they are used to support from the side as a
guide. Their design creates a multi-directional, material-handling system that enables
heavy loads to be moved smoothly along with minimal effort and friction.
They are designed to assist in transferring, directing, or facilitating loading of products
in workplaces such as warehouses, production lines, port cargo handling facilities, semiconductor production systems, FPD production systems, PV, solar glass handling production lines, medical equipment, research laboratories, under-floor facilities of buildings and
offices manufacturing or freight transfer. Similar to a roller systems, the balls are installed
within the table or work surface and the product rolls over the balls and allows for turning,
lifting, directing or transferring from one conveyor line to another.
People with lifting or carrying restrictions resulting from back, neck, shoulder, heart,
and various repetitive strain injuries may benefit from the use of ball transfers technology if
there is a need for lifting or handling products on a repetitive basis within the workplace.
Pneumatic Air Ball Lifters have a unique construction – a combination of a high precision-machined ball transfer with an air cylinder. This unique device uses compressed air
to lift a load/tool from the table surface position and rotate it in any 360 degree direction
in a horizontal plane; an economical labor saving unit. Roll on-Roll off facility dramatically
reduces changeover times.

1- .　3 Cleanroom Type Ball Transfers
Clean room Ball Transfers are used extensively in FPD (Flat Panel Display), PV (Photovoltaic) production lines all over the world due to its innovative technology for alignment
and positioning of glass substrates.
Ball Transfers have been evolving continuously with a new added-value to satisfy panel
makers to improve products yield potential. After it was successfully proven in LCD
post-processing, the application expanded to a variety of new applications. Especially in
recent years, the demand for pre-processing has increased. At present, we have cleared
the fundamental demand for clean room applications and, to meet our customer specific
requirements, we developed a low-cost molded type with superior performance, in addition to machine cut Ball Transfers.

Linear Bushings
■ Standard length type
High grade engineering plastic is used in the construction of
the flange to achieve strength whilst offering a more cost effective option than steel type Linear Bushings.
Since the internal structure is comparable to
that of a conventional linear bushing minimal
design changes are needed to incorporate this
product.

Spherical Rolling Joints
Provide high precision and rigidity with
zero clearance rolling guideways.
Although the integration of spherical rolling
joints provide 2 or 3 degrees of freedom, a
requirement for use in parallel mechanism,
the result is complex and bulky.
Sliding spherical rolling joints having multiple degrees of freedom are also available
but have negative characteristics that include
frictional resistance and internal clearance
problems.

1. Highly Precise
2. Compact Multi-Degrees of Freedom
The single unit provides a greater rigidity and greater compactness than
joints made from integrating rolling joints having 3 degrees of freedom.
3. Highly Suited for Parallel Mechanisms
Optimal for parallel mechanisms requiring high precision, high rigidity, and
compactness.
4. Super-Precise Spherical Surface Processing
Unique processing technology provides super-precise spherical surfaces.
