1/2 inch Arbor

Arbors allow you to attach your hub and blades to the shaft of your wind generator. It is machined on a computer-controlled lathe to exact tolerances using 304 stainless steel. This will attach to any motor/generator shaft that is 1/2 inch in diameter. This arbor will not rust. Arbors made from steel (with the exception of stainless steel) will rust away fairly quickly. Not only is this a waste of your money, it is dangerous! Your wind turbine has to weather hot and cold, dry and wet conditions. Don't settle for an inferior arbor made from improper materials. Included with your purchase: 1/2 inch diameter arbor. The arbor will fit any motor or generator shaft that is 1/2 inch in diameter. The threaded portion of the arbor is 1/2 inch diameter and threaded at 13 TPI (threads per inch). This means you can attach a hub that has a 1/2 inch diameter mounting hole. A stainless steel nut + stainless steel lock washer. This allows you to securely attach a hub to the arbor. Three stainless steel set screws which allow you to securely attach the arbor to the shaft of the motor or generator. Three set screws spaced 120 degrees apart allow for a perfectly balanced arbor. This keeps your rotor spinning smooth and balanced even at very high RPMs
