A bushing, also known as a bush, is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications. We can supply the bronze and brass bushing.

Usually these bushings are used in excavators, crushers, machine tools, turbine generator and other equipment.

We can supply a lot of material for the C93200, C93700, C93800 bushing. Also We can supply the bronze and brass bushing according to customer's request.

Usually the big and large bushing made by centrifugal casting or sand casting. We can supply centrifugal casting bushing and sand casting bushing too. Some small bushings can made by continuous casting rod. We can supply them too. Our factories have many centrifugal casting machines and sand casting equipments.

The Max diameter of our bushing is 2.2 meters.

The Max weight is 5 tons 1 PC finished parts.

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 focus on gear and pinion for crusher. We can supply the standard gear and pinion for Nordberg Symons, Sandvik HYDROCONE H-S type and other non-standard gear and pinion.
