Product Description
Durable Bearing Tungsten Carbide Bushings
Advantages:
(1). Abrasive resistant, corrosion free, good compression property, the most wear-resistant bushing, heat resistance, low maintenance ;
(2). The hardness is 10 times of gold, 5 times of tool steel, 4 times of titanium, oil resistance, separate the harmful medium;
(3) . No shape change, no twist when temperature is above 1000 °C or below 500 °C, long service life, the maximum height can reach 270mm;
