Bronze bushings for cone crushers, excavators, machine tools, and turbine generators. Materials: C93200, C93700, C93800, and custom alloys to customer specification.

Manufacturing: centrifugal casting and sand casting for large diameters (up to 2.2 meters). Small bushings by continuous cast rod. Multiple centrifugal casting machines and sand casting lines in service.

Maximum finished part weight: 5 tons.

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a non-rotating toothed part, called a rack, thereby producing translation instead of rotation.

The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.

When two gears mesh, and one gear is bigger than the other, even though the size of the teeth must match, a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.

Our company focuses on gear and pinion sets for crushers. We can supply standard gear and pinion sets for Nordberg Symons, Sandvik HYDROCONE H-S type, and non-standard gear and pinion sets.
