Description
SKF rod seal:
The reinforced structure design is insensitive to the slight damage
of piston rod and sealing groove and will not leak.
The diameter of the product is in the middle of the design, the
dynamic performance in the groove is good, easy to install.
U - 1023 polyurethane material has a wide working temperature
range, the limit temperature range is-60 °C to 130 °C, and the
long-term temperature range is 30 °C to 110°C.
The product has a star ring, which ensures the precompression and
shrinkage of the seal lip under the condition of high and low
pressure, and improves the reliability of the seal. Good sealing
performance can be achieved even in low temperature working
environment.
Disposable injection molding technology, does not need to go
through the secondary trimming, the size is more accurate, the
performance is superior.
