I’m doing a market research on the pneumatics market and I need the
following information:

1. List of top 50 pneumatics components manufacturers, worldwide. 
2. The list should be divided by revenues size to 1st tier (top 10
companies), 2nd tier (20 next companies) and 3rd tier (last 20
companies).
For each company list it’s location (country) and website
address.
3. 1st tier companies must include annual revenues and market share.
Revenue information for the rest of the companies will be appreciated.
If revenues are not available, I’d like to know what criteria was used
to place it in a one of the groups.

A useful website listing most of the pneumatics companies:

Good Luck!
