Product Presentation of Excavator Extension Arm
The long arm of the excavator is made of Q355B steel, which has good strength and rigidity. The shaft sleeve of the extension arm is generally made of 45# steel, lined with a 40Cr bushing, and the lubrication effect of butter reduces the shear force generated by the frequent rotation of the shaft and the shaft sleeve, thereby prolonging the service life of the extended arm. The shaft sleeve is enlarged. Using a selection of the toughest wear-resistant steels, we can produce excavator long arms for Cat, Demag, Doosan, Hitachi, Hyundai, JCB, Kobelco, Komatsu, Liebherr, Volvo and other popular brands.
