FUJIKURA COMPOSITES for Air Cylinders, Pressure Regulators, Pneumatic Equipment

A.

Since VC-P-4-E, resinous check valve, does not contain oil, the standard specification is no oil type itself.

A.

It's available to purchase our products in US, China, Taiwan and S.Korea.
We introduce you our agencies in each country. Please inquire us.

A.

It's available. Please contact us.

A.

Please inquire us or our agencies directly.

A.

To meet customer's requirements, we make a non-disclosure contract with the customers. Please contact us.

A.

It takes 1 - 2 weeks for standard products.
For special products, it will take 1 - 1.5months.

A.

It's applicable for various sizes as the specialized products.
We have the record of the cylinder with the diameter of φ600mm at the largest.

A.

Their shapes are like silk-hats, and covered with rubber on the synthetic fibers, operating diaphragms parts are designed to be very thin. The characteristics are quite natural rolling action by diaphragms and their superior pressure resistance.

A.

They're air cylinders using BF diaphragms. The diaphragms' rolling action permits us to solve the big problems of air-leakage and friction.

A.

The friction resistance is caused by cylinder's action. The larger the operating resistance value becomes, the more hysteresis-loss becomes larger. Then the rod does not move smoothly.

Please download old type of cylinders' catalogs from herea. (PDF/Japanese)

A.

Old types and new types are different from each other in their outside dimensions. Old types are tubular type and new types are rectangular parallelepiped types in outside.
Besides, there are some differences in the length of the cylinder and inlet port, or in other dimensions.
Since it became a new model and spigot joint for positioning was added to the both ends of the cylinder, it is impossible to attach the brackets for the old models.
Please confirm old and new BF cylinder comparison table for details.
Please download the comparison table of old and new type of BF cylinder from herea. (PDF/Japanese)

A.

Please refer the weight and size table for the weight of cylinders and the sizes of carton boxes at the time of packing shipment from the following link.
Please inquire about the items which are not referred on the table.

A.

Although BF cylinder is a cylinder which was equipped with many features unlike the general packing cylinder, in order to fully utilize the function and to have it used for a long time, there are some notes in handling or installation. Please download handling instructions of BF cylinders from herea. (PDF/Japanese)

A.

It's available to have the following features by using BF diaphragm unlike packing.

1. Almost no air leak.
2.Responsive to minute pressure variations.
3.Virtually no hysteresis-loss in movement

A.

As they have the different sizes each other, please inquire each time you need.
Please understand that there is a cylinder under measurement still depending on the sizes.

A.

Since it varies depending on the use (a working pressure range, a stroke, environment, etc.), it cannot be referred generally. However, it is also possible to set up and real-measure the similar environment according to the customer's request.

A.

A single action type means the cylinder which exhausts the air to single-sided one way. A double acting type means the cylinder drives in the direction of both sides (pressure, inlet). When you make the rod pushed out by the single action type draw in without air pressure, please choose the cylinder with a spring (S1).

A.

FC series is a standard cylinder of our company which uses dry bearings for bearings.
SC series is the cylinder for which the linear ball bearing is used.
Increase of operating resistance to horizontal load can be suppressed more than FC series.

A.

RS and RR always need the air to bleed because they are bleeding type of regulators themselves.
For this reason, the air bleeds even when it's closed completely.
Also RT has the same structure, the air flows out even in the time it's closed completely.

A.

"RS"… Model types (Super precision regulators)
"8" … Set pressure range (840kPa at maximum)
"2" … Pipe port size (Rc1/4)

A.

The specifications for our regulators permit inactive gas.
Please withhold use of combustible gas.

A.

Corresponding to clean room, tap processing is given to the exhaust port at the time of bleeding, and it has the structure whose air does not leak in the clean room,
Moreover, each part article performs pure water washing, and they never be contacted by bare hands at the time of assembling.

A.

Since their main purpose is relief, the amount of leaks is not zero.
The leak of about 10 or less mL/min occurs.
