The general working conditions of wind turbines are very harsh, and the range of temperature, humidity and load changes that need to be borne is large. With its excellent corrosion resistance and high bearing capacity, self-lubricating bearings can be well adapted to changing and harsh working environments. CSB's self-lubricating bearing products, made of polymer self-lubricating materials or pre-added self-lubricating materials in the material, are especially suitable for heavy duty, low speed and harsh conditions (such as extreme temperature, vacuum, high altitude, corrosive and other can not be refueling or difficult to refueling).
