Jigs, molds and workpieces need to be conveyed accurately and smoothly.
With a pneumatically actuated freebear unit, 1 ton of conveyance object can be freely 360° conveyed with a force of only 0.2～0.3KN (20～30Kgf). Positioning can also be performed in a short time.
Besides, with the use of air, the work environment remains clean.
Heavy objects can be freely conveyed and seated
With the ON and OFF of the air valve, the freebears can lift the conveyance object with the force of the air.
You can easily and quickly convey and accurately position jigs and workpieces with a slight force.
They are very useful in combining with assembly lines, and conveying and setting press molds.
By supplying air to the unit, the built-in freebears rise to lift the conveyance object. When the starting frictional resistance (μ) is less than 3/100, they can freely 360° move the conveyance object.
Once the air supply stops, the conveyance object is seated by its own weight.
*Please use the vacuum generator as shown in the figure below if required to force down the cylinder.
Our products are applied to many industries for various purposes and are widely praised by customers.
Square groove insertion type freebear unit
By supplying compressed air, the freebears built in individual pistons rise simultaneously.
By processing a square groove on the machine bed at the time of mounting, it is possible to convey and position jigs, molds and workpieces.
T-groove insertion type freebear unit
You can use it by inserting it in existing T-groove without the need for square groove processing.
It can be inserted only when required or can be freely inserted/extracted, and thus can be conveniently attached onto machines without lifting function.
T-groove insertion type roller unit
The unit with built-in rollers rises and lowers through air pressure.
Compared with the freebear unit, the roller has a smaller starting frictional resistance (μ) in the rotational direction and is suitable for the direction turn and right-angle transfer in production line.
Spring cushion type
This type of single freebear can be buried in existing cushion pin hole or hole drilled in the machine bed and is actuated through the spring.
Design and development of custom-made products to meet the needs of our customers
The freebears can be customized according to the customer’s requirements for shape, size and purpose.
