Industry Solutions
This is our hydraulic sleeve, an internal structural component used in hydraulic cylinders.
The piston moves reciprocally inside the sleeve during operation. The sleeve provides precise guiding for piston movement and contributes to the sealing performance of the hydraulic system.
This is our stainless steel sleeve nut, designed for applications in humid, outdoor, and corrosive environments such as marine equipment, chemical processing systems, and food machinery.
This is our extended wheel nut, designed with a longer threaded body compared to standard wheel nuts.
The extended section ranges from 5 mm to 50 mm, allowing proper engagement in applications involving thick wheel hubs, spacers, or modified rims.
