CHAENG Coal Mill Bearings

NSK tapered roller bearings

NSK is a world-renowned manufacturer of high-quality tapered roller bearings for coal mills. These bearings can support axial loads in either direction. They are made from high-carbon chromium steel. Their Sealed-Clean design provides improved sealing protection and promotes lower grease consumption. Among other features, these bearings are resistant to extreme temperatures.

NSK tapered roller bearings for coal mining are available with different configurations. For instance, the C&U bearings have tapered inner and outer ring raceways and truncated tapered rollers. The increased contact angle increases the axial load carrying capacity. They are also available in EM and EW series. They are available in both pressed steel cages and one-piece machined brass cages. Both cages provide excellent functionality and long operating life.

CHAENG bearing chock

CHAENG bearing chocks are made of SCW480 material, which is durable and suitable for high load and long-term operation. It is also equipped with an oil level observation scale to prevent the bearing from being damaged due to lack of oil lubrication. It prevents dust and dirt from entering the bearing box and ensures reliable operation.

The bearing chock is one of the most important parts of a coal mill, as it bears the impact of various materials. Therefore, it is important to select the bearing chock carefully. It must have high strength, good wear resistance, and good damping performance. CHAENG, as one of the largest steel casting manufacturers in China, can meet the requirements of various coal mills.

NSK self-aligning roller bearings

Coal pulverizers require fine particles of coal in order to make the fuel burn more efficiently. As a result, the coal pulverizer is an essential component of coal-fired power plants. The role of the coal pulverizer is to crush and grind the coal to a very fine powder that can be burned more easily.

NSK offers double-row self-aligning roller bearings to compensate for shaft misalignment and provide maximum operational reliability. These bearings come in fixed and floating designs, and offer high load capacities. They eliminate the need for retaining rings and offer long operating life.

CHAENG bearing bush

The CHAENG coal mill bearing bush is a crucial component for a coal mill, which is essential to the efficient working of the coal mill. The bush is made of a special material and has several important functions. It has excellent bearing capacity and a long service life. It is a vital part of a coal mill and needs to be maintained and repaired in order to keep the mill running smoothly.

The material of the bearing bush is an important factor in determining the life of the bearing. The most common material used for this is metal. It is cheap, easy to machine, and has high bearing properties. It also resists corrosion.

CHAENG bearing seat

A CHAENG coal mill bearing seat is one of the most essential components of the coal mill. It supports the mill trunnion, cylinder, and grinding medium. In addition, it must withstand the non-uniform force generated during operation. Several important factors must be taken into consideration before choosing the right coal mill bearing seat.

In order to prevent excessive wear, the bearing seat should be properly lubricated. It should be greased with red lead oil. Then, it should be positioned in the pitch circle line. It should also meet the requirements for the tooth length and height. The teeth must also be smooth and rounded. It is also important to increase the top clearance for thermal expansion and deformation.
