Turned plain bearing bushings according to DIN ISO 4379
Our turned plain bearing bushings according to DIN ISO 4379 are manufactured with the highest precision and meet the strict requirements of industrial applications. We use CuSn12 as the standard material for these bushings. They are ideal for dynamically stressed bearing points and are characterized by tight tolerances, high concentricity, and excellent surface quality. Thanks to individual manufacturing options, you can tailor each plain bearing bushing precisely to your technical specifications for maximum fit accuracy and long-lasting performance in mechanical engineering, plant construction, and special designs.
Product description: Technical specifications and available materials
These plain bearing bushings are made from various bronze, brass, or steel alloys. Self-lubricating variants contain dry lubricants integrated into the bearing surfaces, enabling maintenance-free use. Depending on the application, different material and lubricant combinations are available to achieve optimum performance in terms of load capacity, corrosion protection, and temperature resistance.

Typical areas of application for plain bearing bushings
Our plain bearing bushings are designed for demanding industrial applications and have proven themselves in a wide range of industries where high load capacity, precision, and durability are required. Typical areas of application are:
for movable structural elements, swivel arms, or bearing points in heavy steel structures that are permanently exposed to high forces.
in machine tools, production facilities, or conveyor technology, where precise bearings and low wear are crucial for process reliability.
for bearing points in excavators, wheel loaders, or cranes that operate continuously under changing loads and weather conditions.
in turntable ladders, pump units, and rescue equipment that must function reliably under extreme operating conditions.
in casting machines, molding systems, or conveyor lines, where plain bearing bushings withstand high temperatures and heavy loads.
Where Do Flanged Plain Bearings Outperform Plain Bearings Without a Flange?
Compared to designs without a flange, a flanged plain bearing offers key functional advantages:
