Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides custom hydraulic cylinders for the waste recycling and scrap processing industry, including scrap shears, balers, shredders, and material sorters. As a national intellectual property advantage enterprise with over 30 years of experience, we design cylinders that resist shock loads, abrasive debris, and corrosive fluids (such as battery acids). Our custom cylinders for scrap shears must generate extremely high forces (up to 1,000 tons) to cut through thick steel. These cylinders have very large bores (up to 500 mm) and short strokes, with heavy-duty construction to withstand impact. We use forged steel heads and caps, and the piston rod is induction-hardened to 60 HRC. The seal system includes a heavy-duty wiper and a metal scraper to remove metal chips. For a US-based scrap recycling company, we supplied a custom shear cylinder for a 1,000-ton guillotine shear. The cylinder has been in operation for over 12 years with only seal replacements. For scrap balers, we provide custom main cylinders that compress scrap into dense bales. These cylinders have long strokes (up to 2,500 mm) and operate at pressures up to 300 bar. We use tie-rod construction for easy maintenance, and we offer replaceable wear rings on the piston. For a European baler manufacturer, we supplied custom cylinders for a car baler, achieving a bale density of 800 kg/m³. The cylinders have a bore of 300 mm and a stroke of 2,000 mm, and they have achieved over 1 million cycles. For shredders, we provide custom cylinders for the feed ram and the grate positioning. These cylinders are exposed to heavy vibration and dust. We use bronze bearings and polyurethane seals, with an optional bellows cover to protect the rod. For a Chinese shredder manufacturer, we supplied custom feed cylinders that have been running for over 5 years in a 24/7 operation. Our manufacturing process includes 100 percent pressure testing, cycle testing, and inspection of rod hardness. We provide a detailed test report and a two-year warranty.
