Bearing problem solved

NSK's L-PPS bearing cage technology is providing an effective solution, both in terms of long term performance and cost, for a compressor manufacturer who was receiving complaints about compressor failures resulting from damage to bearings operating at temperatures above 70°C.

NSK recommended use of bearings with cages made from L-PPS (linear polyphenylene sulphide), a glass fibre reinforced plastic designed for high temperature use at up to 190°C. The material has a high level of chemical resistance and thermal stability.

Since the introduction of bearings with L-PPS cages, complaints to the compressor company have ceased.
