V Pulley Source for Japan - 500 psi Air Compressor

In summary, the speaker is in Japan and has acquired a salvage high pressure (500 psi) air compressor that was junked due to a broken cast iron, 15" double V belt pulley on a 1.25' keyed shaft. They are looking for a source to replace the pulley, and possible options include McMaster-Carr, Grainger, and W.M. Berg. The speaker also suggests exploring different drive options as long as the ratio remains the same.

I am in Japan and recently acquired a salvage high pressure (500 psi) air compressor. It was junked because the large spoked flywheel v-pulley on the compressor had broken. The pulley is cast iron, about 15", double V belt, keyed shaft about 1.25'.

Could you suggest a source for a replacement of such a v pulley?

(Power for this unit is a Kohler 12 HP electric stat engine ... runs perfectly. Would like to get this unit up and running again.)

Thanks,

E Lee

Check into McMaster-Carr, http://www.mcmaster.com/ or Grainger http://www.grainger.com/Grainger/wwg/start.shtml

You can also try W.M. Berg. Here is a worksheet you can fill out and fax to them and they will see if they can match what you need: http://www.wmberg.com/faxbelt.html

I'm sure you'll have to pay a bit more for overseas shipping.

Keep in mind as well that just because the thing started with a double-V pulley is no reason to keep it that way. Feel free to substitute a chain drive, gears, Gilmer drive, single-V, etc., as long as you keep the same general ratio that it's designed for. 500psi is not actually very high for a compressor, so you shouldn't have to worry too much about tolerances. (A little pocket-size 12 VDC automotive compressor goes up to 300 psi; heavy-duty home types can hit 2500, and I don't even know what the upper limit for industrial models is.)
 

1. What is a V Pulley?

A V pulley is a type of pulley that has a V-shaped groove on the outer surface. It is often used in conjunction with a V-belt to transfer power and rotational motion between two shafts.

2. What is the purpose of a V Pulley Source for Japan - 500 psi Air Compressor?

The purpose of a V Pulley Source for Japan - 500 psi Air Compressor is to provide a means of transferring power from the air compressor to other machinery or equipment in Japan. The 500 psi rating indicates the maximum air pressure that the pulley can withstand.

3. How does a V Pulley work?

A V pulley works by using the friction between the V-belt and the V-shaped groove to transfer power and rotational motion. As the V-belt is pulled by the rotating pulley, it creates tension and causes the pulley to rotate, transferring the power to the connected machinery.

4. Why is the V Pulley Source specifically for Japan?

The V Pulley Source is specifically designed for Japan due to the unique specifications and requirements of Japanese machinery and equipment. This ensures that the pulley is compatible and safe to use with the air compressor in Japan.

5. How do I choose the right V Pulley for my air compressor?

To choose the right V Pulley for your air compressor, you will need to consider factors such as the horsepower of the air compressor, the type of V-belt used, and the maximum air pressure that the pulley can withstand. It is important to consult the manufacturer's guidelines and specifications to ensure compatibility and safety.
