[STANDARD PNEUMATIC BEARING]
“STANDARD PNEUMATIC BEARING” used to support various rotating bodies. The standard materials are Aluminum, SUS-304. Main applications are for guide rolls of thin film, thread, wire etc. This bearing is of less cost and easier to handle than the other competing products.
[Arrangement to support a roll by Standard PNEUMATIC BEARINGS mounted on a swivel] Illustration at right shows an arrangement to support a roll by two standard “PNEUMATIC BEARINGS” each mounted on a swivel. This swivel mechanism compensate the error in installation, variation of the temperature, etc.
[Arrangement to support a roll by ARC TYPE PNEUMATIC BEARING mounted on the swivel]
Illustration at right shows an arrangement to support the guide roll by the combination of the semicircle PNEUMATIC BEARING and the swivel.
[ARC TYPE PNEUMATIC BEARING mounted on a Swivel] semicircle PNEUMATIC BEARING to float the rotor by the compressed air supplied at the inlet while the permanent magnet under the stator attracts the roll. The gap in between the rotor and stator is determined by controlling the floating force by the compressed air vs. the attracting force by the Drawing 3. The practical operation gap is about 100〜5μm. One of the advantages of this bearing is that the rotor with the bearing can be removed through the other half of clearance. The Drawing 3-2 shows a semicircle PNEUMATIC BEARING mounted on the swivel shown in the Drawing 3-3.
[Various LINEAR PNEUMATIC BEARINGS]
Illustration at right shows a “LINEAR PNEUMATIC-MAGNETIC BEARING” utilizing the magnet force and the force of compressed air. The operation gap between the rotor and stator is normally within 100〜5μm. As this is quite contrary to the other manufacturers' products which maintain the gap by the balance of air pressure, the supporting power is much bigger and machining and control becomes easier by utilizing the electro-magnet. A lot of new application should exist.
[Table equipped with Pneumatic]
Illustration at right shows an application to a big table where a fine control of the lifting amount can be made by the combination of the force of compressed air and the force of either permanent or electro-magnet. This is ideal for lapping lathes and also grinding machines.
