Screw compressors are used in environments where they are exposed to such chemicals as compressor oil, refrigerants, and ammonia gas. Consequently, bearings for screw compressors must be highly resistant to oil and heat.
Papermaking machine bearings operating under hightemperature conditions are vulnerable to problems such as fracturing of the inner ring, which can result in work stoppages.
Construction equipment used in harsh environments risk contamination from dust, mud, and huge loads, and require a certain degree of ruggedness that is different from the requirements of a common passenger vehicle. NSK has developed bearings for such equipment.
