UNEbearing sleeve, often referred to as a palier à douille, is a type of plain bearing that facilitates smooth movement between two components by reducing friction.
Types of bearing sleeve
Following is the comprehensive bearing sleeve types we need to talk about,
Bagues en bronze
- Material: Made from bronze, which is known for its strength and durability.
- Applications: Often used in high-load, low-speed applications, such as pumps, machinerie industrielle, and electric motors.
- Avantages: Great wear resistance, good load-bearing capacity, and good resistance to corrosion.
Flanged Bushings
- Design: Features a flange (or lip) at one end to help position the bushing or offer a load-bearing surface.
- Applications: Common in situations where axial loads are present in addition to radial loads.
- Avantages: Helps prevent axial movement and provides additional support.
Type de polymère
- Material: Made from high-performance plastics like nylon or PEEK.
- Applications: Often used where lubrication is difficult or undesirable.
- Avantages: Lightweight, corrosion-resistant, and low maintenance. These bushings also reduce noise and have good chemical resistance.
Neoprene Bushings
- Material: Made from neoprene, a type of synthetic rubber.
- Applications: Used in vibration-damping applications, like automotive suspension systems or marine environments.
- Avantages: Excellent flexibility and resistance to weather, oil, and chemicals.
Bagues PTFE
- Material: Made from polytetrafluoroethylene (PTFE), which is a non-stick material.
- Applications: Used in high-temperature environments and situations requiring low friction.
- Avantages: Autolubrifiant, excellent thermal stability, and resistant to wear and chemicals.
Steel Bushings
- Material: Made from steel, offering high strength.
- Applications: Used in heavy-duty applications requiring high load capacity, such as agricultural machinery or heavy equipment.
- Avantages: Extremely durable and has high load-carrying capacity, but requires lubrication to prevent wear.
Rondelles de butée
- Design: Flat washers used in combination with bushings to handle axial loads.
- Applications: Used in assemblies that require resistance to thrust or axial loads.
- Avantages: Increases the lifespan of the bushing system by reducing wear and absorbing axial forces.
Cylindrical Bushings
- Design: Simple cylindrical shape that allows for radial load distribution.
- Applications: Used in a wide range of applications, including automotive and industrial machinery.
- Avantages: Easy to install and remove, suitable for radial loads.
Bagues en graphite
- Material: Contains graphite, which acts as a lubricant.
- Applications: Used in high-temperature or dry-running conditions where other lubricants fail.
- Avantages: Self-lubricating and excellent for applications that experience extreme temperatures.
Metallic Self-Lubricating Bushings
- Design: Infused with solid lubricants, like graphite or PTFE.
- Applications: Ideal for applications where external lubrication is impractical, such as in aerospace and automotive industries.
- Avantages: Maintenance-free and offers a long service life with low friction.
POM Bushings (Polyoxymethylene)
- Material: Made from engineering thermoplastic known as polyoxymethylene (POM).
- Applications: Used in applications requiring high dimensional stability and low friction.
- Avantages: Good mechanical strength, low friction, and resistance to abrasion.
Sliding Plates
- Design: Flat, plate-like components that allow for sliding motion.
- Applications: Used in bridge structures, heavy machinery, and construction for load-bearing with sliding functionality.
- Avantages: Offers low friction and wear resistance in large sliding motions.
Aluminum Bushings
- Material: Made from aluminum, offering lightweight properties.
- Applications: Often used in applications where weight reduction is critical, like aerospace and automotive.
- Avantages: Corrosion-resistant, poids léger, but not as strong as steel.
Bagues bimétalliques
- Material: Made by combining two different metals, typically steel backed with a bronze or other alloy layer.
- Applications: Used in high-load, low-speed applications such as automotive engine components.
- Avantages: Combines the strength of steel with the anti-friction properties of softer metals like bronze.
Bagues en laiton
- Material: Made from laiton, which has good machinability and corrosion resistance.
- Applications: Often used in plumbing, electrical, and industrial machinery due to its resistance to water and oils.
- Avantages: Good wear resistance, corrosion-resistant, and easily machinable.
Composite Bushings
- Material: Made from a combination of materials such as plastics reinforced with fibers.
- Applications: Used in industries where lightweight and low friction are critical, such as automotive or aerospace.
- Avantages: Lightweight, autolubrifiant, and corrosion-resistant.
Bagues à bride
- Design: Same as flanged bushings mentioned above.
- Applications: Used where both axial and radial loads need support.
- Avantages: Easy to position and support with additional load-bearing capacity on the flange.
Nylon Polymer Bushings
- Material: Made from nylon, a durable plastic polymer.
- Applications: Suitable for applications requiring resistance to wear, produits chimiques, and moisture, such as conveyor systems or water applications.
- Avantages: Autolubrifiant, corrosion-resistant, and offers excellent noise reduction.
