Injection Molded Plastic Washer Bushing 45mm Oyster Double Round
Special plastic injection molding fixing washer bushing has a
double round body design that smaller one is placed in bigger one
and both are connected by four bars , there is a hole in middle of
bar for further fixing purpose when it is assembled with other
Plastic injection molding fixing washer bushing is made from nylon
PA with grade 66 , this material is quite good for high
requirements on assembly and use conditions .
Low friction and good self-lubricant for a long service
Wide working temperature from -30℃ to 150℃ for the most areas with
different climate .
Colorful choices for many demands
