Achieving zero friction resistance. A cylinder with no wear or dust generation, utilizing air bearings. Customizable in small, thin, and ceramic sintered forms.
The air bearing cylinder is a high-performance product that employs innovative air cylinder technology. Its core lies in the air bearings mounted on the rod guide section. This advanced design allows for non-contact between the rod and guide, reducing sliding resistance to zero. Leveraging this characteristic, the air bearing cylinder achieves precise drive at micro-loads and low speeds. With soft-touch operation and high-precision load control, it is ideal for applications requiring strict control, such as precision grinding equipment. Furthermore, it can be compatible with clean room environments, making it suitable for a wide range of industrial fields. One of its main features is the adoption of porous metal sintered air bearings, which provide high lateral rigidity that surpasses conventional products. Additionally, special adaptations through free design according to customer needs are possible, accommodating various customizations such as miniaturization, slim design, and the use of ceramic sintered materials. In fields such as precision equipment manufacturing, semiconductor industry, and medical device development, where advanced control and cleanliness are required, the air bearing cylinder opens up new possibilities.

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 ranges from Φ10 to Φ100, with special adaptations possible up to Φ190. - There are two types of operation: single-acting extrusion type and double-acting type. - Custom products tailored to customer specifications can be manufactured. - Cleanroom compatibility is also possible. 【Custom Examples】 - Small air bearing cylinder - Thin air bearing cylinder - Air bearing cylinder "rotational constraint specification (double-acting type)" → Improved quality, reduced defective products, 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. Due to its ceramic material, it can be used in environments that dislike conductivity (battery manufacturing). It has heat resistance and can be used in high-temperature environments (ceramic sintered body).

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 200 [kPa] of air 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 indicates the sliding resistance.
