We are a custom gear manufacturer, so we do not maintain large amount of standard stock gears. However, we do keep commonly used raw materials and semi-finished blanks in stock — such as 20CrMnTi and 42CrMo round bars, and pre-heat-treated blanks for frequent sizes. This allows us to respond quickly to urgent orders. If you need a standard gear off-the-shelf, we can recommend trusted suppliers, but our core business is custom manufacturing. For custom orders, we hold no finished stock until your order is placed.
