机芯系列减震器Strut Cartridges一力机芯系列减震器外筒采用钢管精抽技术,有效保证了配合精度;使用高强度微裂纹镀铬的工艺,提高了连杆金属表面硬度,从而增加了产品的抗侧向力合抗摩擦性能!Steel tube precision drawing is introduced to the outer cylinder, which ensures the fitting accuracy. Techniques of high-strength microcrack chrome plating on the connecting rod improve the rigidity of the metal surface, so that the resistance against the side force and friction is improved.
