SS304-Rod/Cylindrical Pin Hinges Open Bush Type Dia-30/40/50mm

Stainless Steel (SS) cylindrical rod hinges, often referred to as barrel hinges, weld-on hinges, or bullet hinges, are heavy-duty, compact, and rust-resistant hardware designed for seamless, robust movement in metal doors, gates, and industrial applications. They consist of a cylindrical barrel and a pin that allows for a smooth, often 270-degree or 360-degree, pivot motion.

Key Features and Description

Design & Structure: These hinges have a cylindrical, “bullet-shaped” body, usually consisting of two main parts: the male and female halves, often featuring a removable pin for lift-off functionality.

Material: Made from premium stainless steel (such as 304 or 316 grade), ensuring high rust resistance, corrosion resistance, and long-term durability.

Installation: Typically designed for welding onto metal frames or, in some cases, surface-mounted for industrial or residential applications.

Load Capacity: Suitable for heavy-duty applications, these hinges can withstand significant weight and stress.

Appearance: They feature a sleek, often polished or brushed finish that provides a modern, clean, and unobtrusive look.

Common Applications
Metal Doors and Gates: Frequently used on steel doors, industrial cabinets, and heavy gates, including those in corrosive environments.
Machinery and Industrial Equipment: Used in enclosures, panels, and machinery where a strong, durable, and reliable pivot point is needed.
Furniture and Cabinets: Suitable for heavy-duty cabinet doors and specialized furniture applications.
Marine and Outdoor Use: High-grade (316) stainless steel versions are suitable for yachts, boats, and outdoor, weather-exposed environments.
Typical Specifications
Dimensions: Common sizes include 95 mm in length with a 9 mm diameter, or 64 mm (2.5 inches) for heavy-duty round hinges.
