130904000043B006 Armrest box 500 rotating pin Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130904000043B006 armrest box 500 rotating pin is a core rotating component of the original factory-customized cab armrest box. It is compatible with the 500 series armrest boxes of various engineering machinery cabs. It is mainly used for the rotation connection and positioning of the armrest box flip cover and adjustment mechanism. It has the functions of flexible rotation, stable anti-vibration, wear resistance and impact resistance, and torque stability. It is suitable for bumpy operations in mines and construction sites, preventing rotation jamming, loosening and breakage, ensuring smooth and noiseless flipping of the armrest box, ensuring stable support and adjustment functions of the armrest, and improving the convenience of driving and riding operations.
This product is an original factory compatible accessory, precisely matching the 500 series armrest boxes of SANY, XCMG, Caterpillar and other series of construction machinery cabs. It adopts CNC precision machining and surface hardening treatment process, and is compatible with the original armrest box rotation interface and installation position. It can be quickly installed without complicated adjustment, and can withstand bumpy, high and low temperature and dusty and oily working conditions. It rotates smoothly and positions accurately.
