Bushings: Essential Components for Rotary Applications

A bushing, commonly referred to as a bush, is an independent plain bearing designed to be inserted into a housing. It provides a durable bearing surface for various rotary applications. Our company specializes in supplying high-quality bronze and brass bushings, tailored to meet the specific needs of our clients.

These bushings are integral components in a wide range of heavy-duty machinery, including excavators, crushers, machine tools, and turbine generators. Their primary function is to reduce friction between moving parts, thereby enhancing the efficiency and longevity of the equipment.

We offer bushings made from a variety of materials, including C93200, C93700, and C93800 bronze alloys. These materials are chosen for their excellent wear resistance, high load-bearing capacity, and superior corrosion resistance. Additionally, we can customize bushings according to specific customer requirements, ensuring optimal performance in any application.

Our manufacturing capabilities include both centrifugal casting and sand casting processes, which are ideal for producing large and heavy bushings. Centrifugal casting ensures a dense, uniform structure, while sand casting allows for greater flexibility in design and size. For smaller bushings, we utilize continuous casting rods, which provide consistent quality and precision.

Our state-of-the-art facilities are equipped with numerous centrifugal casting machines and sand casting equipment, enabling us to handle large-scale production with ease. We can produce bushings with a maximum diameter of 2.2 meters and a maximum weight of 5 tons per single finished part.

Gear and Pinion for Crushers

A gear, also known as a cogwheel, is a crucial rotating machine component designed with cut teeth or cogs. These teeth mesh with another toothed part to transmit torque effectively. In most cases, the teeth on one gear are of identical shape, and often, the other gear in the pair shares the same tooth profile. When two or more gears operate in sequence, they form a gear train, commonly referred to as a transmission. Such gear arrangements can generate a mechanical advantage through a specific gear ratio, making them a fundamental example of a simple machine. Geared devices are capable of altering the speed, torque, and direction of a power source. While the most common application involves gears meshing with other gears, a gear can also engage with a non-rotating toothed component, known as a rack, resulting in translational motion rather than rotational movement.

In a transmission system, gears function similarly to the wheels in a crossed belt pulley system. One of the key advantages of gears is that their teeth prevent slippage, ensuring efficient power transmission. When two gears mesh, and one gear is larger than the other, a mechanical advantage is achieved. This is because the rotational speeds and torques of the two gears are inversely related, allowing for precise control over the output motion.

Our company specializes in providing high-quality gears and pinions specifically designed for crushers. We offer standard gear and pinion sets for a variety of crusher models, including Metso gyratory crushers, Nordberg Symons cone crushers, and Sandvik HYDROCONE H-S type crushers. Additionally, we are capable of manufacturing non-standard gear and pinion sets tailored to meet unique operational requirements. Our products are engineered to deliver exceptional durability, precision, and performance, ensuring optimal functionality in demanding crushing applications.

The gears and pinions we supply are crafted from premium materials, ensuring resistance to wear and tear even under extreme conditions. With precise tooth profiles and robust construction, our components provide reliable power transmission, minimizing downtime and maximizing productivity. Whether you require standard or custom solutions, our expertise in gear and pinion manufacturing guarantees that you receive components that meet the highest industry standards.
