Plain bearings are a simple yet powerful solution for guiding and supporting mechanical motion.
They are also commonly referred to as sliding bearings in engineering terminology, bushings in practical applications and maintenance contexts, and sleeve bearings especially in North America.
With types such as solid bearings, flanged bearings, split bearings, and grooved bearings, they serve industries that require robustness, ease of assembly, and reliability.
Whether you are designing a hydraulic system or sourcing parts for heavy-duty machinery, working with the right bearings manufacturer or provider ensures performance and peace of mind.
Types of plain bearings
Plain bearings come in several forms, depending on geometry and application. While the term bushing is sometimes used, especially in commercial catalogs, we focus here on bearing terminology for clarity.
Solid bearings
A basic cylindrical shape with no flange or split. Ideal for radial loads and consistent operating conditions.
Flanged bearings
Equipped with a flange at one end to aid axial positioning and prevent movement along the shaft. Common in housings and mounts.
Split bearings
These are cut along their length, allowing easier assembly and maintenance — especially for large shafts or enclosed systems.
Grooved bearings
Include one or more internal lubrication grooves. These enhance grease distribution and help prolong bearing life in poorly lubricated environments.
Materials and treatments
The choice of material impacts performance, friction, lifespan, and operating conditions. Common options include:
-
Steel: for strength and dimensional precision (often case-hardened or surface-treated)
-
Bronze: excellent for wear resistance and thermal stability
-
Sintered metals: self-lubricating due to porous structure
-
Polymers: lightweight, corrosion-resistant, used in clean or wet environments
-
Composite materials: combinations of metal and PTFE or fiber for special friction or chemical resistance
Many plain sleeve bearings also feature grooves, knurls, or internal reservoirs to enhance lubrication retention.
Applications in industry
Plain bearings are used across sectors where rotational or linear movement is required without the complexity of rolling bearings. Typical applications:
-
Construction equipment: arms, booms, lifting systems
-
Agricultural machinery: sprayers, seeders, pivot joints
-
Mining and drilling: pins and joints exposed to dust and vibration
-
Hydraulic cylinders: bushings at pivot points or ends
-
Wind turbines and energy systems
-
Railway components and presses
-
Industrial automation: linear guides and slides
Choosing the right provider
When selecting a plain bearing provider or bearings manufacturer, it’s essential to evaluate:
-
Product range and customization capabilities
-
Materials and treatment options
-
Engineering support and documentation
-
Delivery speed and technical certifications
For engineers and buyers, access to accurate engineering information bearings is critical for correct sizing, installation, and maintenance.
