Achieving zero friction resistance. A new cylinder with air bearings that has no wear or dust generation has arrived.
The "Air Bearing Cylinder" is an air cylinder that employs air bearings in the rod guide section. Since there is no contact between the rod and the guide, there is no sliding resistance. This lack of resistance allows for soft-touch precision driving at micro-loads and low speeds. It can output to targeted values, making it suitable for applications that require precise load control, such as precision grinding machines. It is also compatible with clean room environments. 【Features】 ◆ By adopting air bearings (static pressure bearings) in the piston and rod guide sections, friction resistance is zero. ◆ The use of porous metal sintered air bearings achieves higher lateral rigidity compared to conventional products. ◆ Special adaptations are possible through free design. 【NEW】 ◆ Air Bearing Cylinder "Rotational Constraint Specification (Double Acting Type)" ◆ Air Bearing Cylinder "Copper Ion-Free Type" are also available for proposal.

basic information
- By adopting air bearings for the piston rod and guide section, there is no friction resistance as it strokes non-contact. - The use of porous metal sintered air bearings provides higher lateral rigidity compared to conventional products. - Lower consumption flow rate compared to other air bearing types such as orifice types (orifice types can also be manufactured). - Standard lineup from Φ10 to Φ100. Special adaptations available up to Φ190. - Two types of operation: single-acting extrusion type and double-acting type. - Custom manufacturing for special specifications to meet customer requirements is possible. - Cleanroom compatibility is also available. 【NEW】 - Air bearing cylinder "Rotational Constraint Specification (Double-Acting Type)" → Improved quality, reduced defects, high durability. - Air bearing cylinder "Copper Ion-Free Type" → Can be used in environments free of copper ions as it does not contain copper materials. Suitable for use in environments that dislike conductivity (battery manufacturing). Heat-resistant and can be used in high-temperature environments (ceramic sintered body).

Applications/Examples of results
It is adopted in devices that require precision and accuracy. ● Self-weight cancellation of the processing head and sensor head (balancer) ⇒ LCD lamination, three-dimensional measuring machines ● Precision pressure control ⇒ Various bonding, mounting devices, and peripheral equipment for semiconductor and LCD manufacturing ● Machine tools ⇒ Nano processing machines, polishing machines, welding machines, etc. ● Tension control ⇒ For high-performance fiber processing machines By combining with our regulators [RS][RS.M/S], more advanced control becomes possible.

About Cylinder Thrust Hysteresis This is a diagram showing the cylinder thrust hysteresis of the Fujikura Rubber BF Cylinder (φ20) and the Air Bearing Cylinder (φ20). It illustrates the cylinder thrust when an air pressure of 200[kPa] is applied to the thrust ports of each cylinder while the rod is stroked (reciprocated). The rod stroke indicates the amount of contraction from the maximum extension. The difference in thrust during the reciprocation of the stroke represents the sliding resistance.
