Injection Molded Plastic Washer Bushing 45mm Oyster Double Round Body Design
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 pieces .
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
