•Requirement of long-term and smooth operation

In the process of material transfer, the unplanned downtime will limit the delivery efficiency of materials, even affect the delivery time or delay the customer's travel, which requires bearings to be with high reliability.

•Different use performance is required for special occasion

For example, during the transmission process of materials, the local position of heat treatment equipment is with high temperature, which requires bearings to have good performance of high temperature resistance and operate safely and reliably under this environment. Due to the corrosion of sea salt with high humidity, bearings should own good performance of corrosion resistance during the material transfer process in the port.

•Low pollution in the process of transmission

During transmission, bearings are required to have good sealing performance so as not to pollute the products due to leakage of lubricating grease. Meanwhile, it is necessary to prevent debris from intruding into bearings.

•Harsh Operating Environment

During the transmission process, the pollutants whether transporting dirt, abrasive coal, metal, cement, or dry and dusty grains, will frequently destroy bearings’ seal, which causes the premature failure of bearing and affects the operation of the whole transmission system.

•Low Noise

When labors work near to the transmission system, noise will act on the central nervous system of the brain through hearing organs, which is harmful to the physical and mental health of the human being, so it is necessary to effectively control the harm of noise and reduce noise pollution. As the key component of the transmission system, bearings require long-term low noise and smooth operation.
