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.
