PLAIN CYLINDRICAL BUSHING: THE NATURE AND APPLICATION
specializing in Plain cylindrical bushing
Plain cylindrical bushing, also known as a plain bearing or a sleeve bearing, is a simple type of bearing that carries a load by sliding or rotating along a shaft. Traditionally, they are manufactured from bronze due to its excellent friction properties and high resistance to wear and tear. Often, these bushings are also perforated or port-lubricated to allow for better lubrication, enhancing the service life of both the bushing and the machinery in which it is used.
FLANGE BUSHINGs share the same construction characteristics as plain cylindrical steel-backed bushings with one distinguishing feature – a flange or rim at one end of the bushing. This flange provides axial guidance, prevents the bushing from sliding out of the housing and helps to support larger loads. It can also compensate for misalignment and provide additional surface area for heat dissipation.
Just like their plain cylindrical counterparts, flange bushings also feature a sintered bronze layer, making them self-lubricating and maintenance-free.
Plain cylindrical Steel backed bushing & flange bushing
Bearings play a crucial role in reducing friction and wear between moving parts in various machinery. Among the different types of bearings available, plain cylindrical steel-backed bushings and flange bushings, particularly those with a sintered bronze layer, have gained considerable popularity for their self-lubricating and maintenance-free features.
The plain cylindrical steel-backed bushing is a composite bearing that features a robust steel backing for structural support and a sintered bronze layer that provides the self-lubricating properties.
The steel backing layer gives the bearing exceptional load-carrying capacity and heat dissipation capabilities. This steel layer ensures that the bushing can withstand the physical stresses of heavy machinery without deformation.
The sintered bronze layer, on the other hand, is created through a process that fuses bronze powder into a solid structure that maintains tiny pores. These pores are then filled with a lubricant, providing the bushing with self-lubricating properties. This results in a bearing that requires no external lubrication, making it virtually maintenance-free.

Plain Bearings: Cylindrical and Flange Bushings Explained
1. Overview of Plain Bearings
Plain bearings, also known as sleeve or journal bearings, are simple components designed to reduce friction between moving parts without rolling elements. They consist of a bearing surface that directly supports rotational or sliding motion. Cylindrical and flange bushings are specialized types tailored for specific applications.
2. Types of Bushings
- Cylindrical Bushings: Simple sleeve-like bearings used for radial loads. Ideal for applications requiring compact design and smooth rotational motion.
- Flange Bushings: Feature a protruding flange (rim) for axial positioning, preventing lateral movement. The flange size is critical for mounting stability and load distribution. Larger flanges suit high axial loads, while smaller ones save space.
3. Material Composition
- Steel Backing: Provides structural strength, durability, and resistance to deformation under heavy loads.
- Sintered Bronze Layer: A porous, self-lubricating material created by sintering (compacting and heating bronze powder). The pores retain lubricants (oil or grease), enabling continuous lubrication during operation.
4. Self-Lubrication Mechanism
The sintered bronze layer releases lubricant under heat and friction, reducing wear. This eliminates the need for external lubrication, making them ideal for hard-to-access or high-maintenance environments.
5. Key Advantages
- Low Maintenance: Self-lubricating properties minimize downtime.
- Longevity: Robust steel-backed construction withstands heavy loads and harsh conditions.
- Versatility: Suitable for radial and axial loads (flange type).
- Cost-Effective: Reduced maintenance and long service life lower total ownership costs.
6. Industrial Applications
- Automotive: Suspension systems, engines, and gearboxes.
- Machinery: Conveyors, pumps, and agricultural equipment.
- Construction: Excavators, cranes, and hydraulic systems.
- High-Temperature/Contaminated Environments: Ovens, mining equipment, where external lubrication is impractical.
7. Performance Considerations
- Load Capacity: Steel backing supports high radial loads; flange bushings handle combined radial/axial loads.
- Speed and Temperature: Suitable for moderate speeds. Sintered bronze performs well in temperatures up to 250°C (482°F).
- Alignment: Proper shaft alignment is critical to prevent uneven wear.
- Installation: Ensure press-fit tolerances and avoid damaging the bronze layer during mounting.
8. Selection Criteria
- Flange Size: Match flange diameter/thickness to axial load requirements and mounting space.
- Dimensions: Inner/outer diameter and length must align with shaft and housing specifications.
- Environment: Consider exposure to dust, moisture, or chemicals. Optional coatings (e.g., PTFE) enhance corrosion resistance.
9. Maintenance Tips
Though designed for minimal upkeep, periodic checks for wear, contamination, or lubricant depletion (in non-oil-impregnated versions) extend service life.
10. Comparison with Other Bearings
- Rolling Element Bearings (e.g., ball bearings): Better for high-speed applications but require more maintenance.
- Polymer Bushings: Lighter but less load capacity.
- Solid Bronze Bushings: Durable but lack self-lubrication.
Conclusion
Steel-backed cylindrical and flange bushings with sintered bronze layers excel in demanding industrial settings. Their durability, self-lubrication, and adaptability make them a reliable choice for reducing friction and extending machinery life. By selecting the correct flange size, material, and dimensions, these bearings optimize performance across diverse applications.
We understand that each industry and application can present unique requirements. That’s why we offer our CuSn8 bronze bearings in three different executions to better cater to your needs:
- Plain Bearing with Grease Pockets: This design features grease pockets that store and distribute lubricant across the bearing’s surface, reducing friction, and prolonging the bearing’s lifespan. This makes them a great choice for applications where regular lubrication might be challenging.
- Flanged Bearing with Grease Pockets: These bearings incorporate a flange or a rim at one end, providing axial location, and preventing the bearing from slipping out of place. Just like the plain bearing, these also have grease pockets for enhanced lubrication. They’re an ideal choice for applications where axial loads and misalignment might be a concern.
- Plain Bearing with Lubrication Holes: This version of our CuSn8 bronze bearings features lubrication holes, instead of pockets. These holes allow for continuous lubrication, reducing friction, and offering superior performance in high-speed applications.
By offering these three variants, we aim to provide a comprehensive solution for your bearing needs, ensuring that you can select the right bearing type that aligns perfectly with your application’s requirements.
