Plain Bearings

Reliable solution for long-lasting and quiet operation

Plain bearings represent one of the fundamental building blocks of modern industry and mechanical engineering. Due to their simplicity, robustness, and wide range of designs, they provide reliable performance even in demanding operating conditions where high loads, repetitive movements, or limited installation space are present. They are used in the automotive industry, hydraulics, agricultural and construction machinery, as well as in many other applications requiring precision and long service life.

Importance and application of plain bearings

Plain bearings serve as a connecting element between two surfaces, enabling smooth sliding and reducing friction. Since they do not contain rolling elements such as balls or rollers, they are easier to install and often better suited for specific applications where rolling bearings are not applicable. They are also characterized by quiet operation and resistance to vibrations, making them indispensable in many industrial sectors.

Types and properties of plain bearings

Within the category of plain bearings, various designs are available to meet specific requirements:

• Spherical plain bearings – allow transmission of radial and axial loads and accommodate angular misalignments.
• Rod end bearings – suitable for dynamic applications and often used together with hydraulic cylinders.
• Hydraulic plain bearings – designed for high pressures and long-term performance in hydraulic systems.
• Bushings – a simple and cost-effective solution for diverse industrial applications.

Depending on technical properties, different materials and dimensions can be selected:

• Materials: iglidur, steel + PTFE, steel + plastic, sintered bronze. Each material offers specific advantages such as high wear resistance, self-lubrication, or load capacity.
• Thickness: precise choice of thickness (e.g. 1.5 mm, 2 mm, 2.5 mm) enables optimal adaptation to each application.
• Stock availability: wide range in stock ensures fast delivery and uninterrupted production.

Advantages of quality plain bearings

Choosing high-quality plain bearings brings numerous advantages:

• long service life even under high loads,
• quiet operation without unnecessary vibrations,
• easy installation and maintenance,
• wide application range – from the automotive industry to construction,
• cost efficiency thanks to reduced need for additional lubrication.

How to choose the right plain bearing

When selecting the right plain bearing, several factors need to be considered:

• Load capacity – determines whether more robust designs, such as spherical plain bearings, are required.
• Operating environment – for humid or dusty conditions, materials with higher resistance are more suitable.
• Dimensions – thickness and inner diameter must match the existing assembly.
• Material – choice between steel, bronze designs, or self-lubricating composites.
