Oilless bushings, also known as Glidlager in German and Gleitlager in Swiss German, are a type of bearing that does not require lubrication to function. They are designed to reduce friction between moving parts and are commonly used in various applications where maintenance is minimal or impossible, such as in automotive, aerospace, and industrial machinery.

These bushings are typically made from a variety of materials, including but not limited to:

1. Bronze: A common material for oilless bushings, offering good wear resistance and self-lubricating properties.
2. Plastic: Materials like (ptfe), Nylon, and UHMWPE (Ultra-high-molecular-weight polyethylene) are often used for their low friction and resistance to corrosion.
3. Metal-impregnated: These bushings have a porous metal matrix that is impregnated with a lubricant, such as oil or graphite, which is released over time to reduce friction.

The selection of the material for an oilless bushing depends on the specific application requirements, including the load, speed, temperature, and environmental conditions.

Oilless bushings offer several advantages:

• Low maintenance: They do not require regular lubrication.
• Long service life: Due to the self-lubricating properties, they can last longer than traditional bearings.
• Corrosion resistance: Many materials used are resistant to various types of corrosion.
• Wide operating temperature range: Some materials can operate in extreme temperatures.

However, they also have some limitations, such as:

• Limited load-bearing capacity: They may not be suitable for applications with very high loads.
• Sensitivity to contamination: Some materials can be affected by dirt or debris in the environment.

When selecting an oilless bushing, it's important to consider these factors to ensure it meets the needs of the specific application.

The 45x50x40mm Oilless Bushing, also known as Glidlager or Gleitlager, is a self-lubricating bearing component designed for applications where the use of traditional oil or grease lubrication is not feasible or desired. These bushings are made from materials that have inherent lubrication properties, eliminating the need for external lubricants.

The 45x50x40mm dimensions refer to the outer diameter, inner diameter, and width/height of the bushing, respectively. The specific size allows for installation in a wide range of applications, such as rotating machinery, shafts, and other mechanical components.

The key benefit of oilless bushings is their ability to operate in environments where traditional lubricants may degrade, leak, or contaminate the surrounding area. They are also suitable for high-speed and high-temperature applications where traditional lubricants may fail.

Glidlager and Gleitlager are common terms used to refer to self-lubricating bearings in the industry. These bushings provide a low-friction, wear-resistant surface that helps reduce maintenance costs and extend the service life of mechanical components.

In summary, the 45x50x40mm Oilless Bushing, Glidlager, Gleitlager is a self-lubricating bearing component designed for applications where external lubricants are not suitable. Its dimensions allow for installation in a variety of mechanical systems, and its self-lubricating properties ensure smooth, reliable operation.

The basic features

With CusN6.5P0.1 or CusN8P0.3 bronze as the matrix, the bronze hole layout bearing is designed with uniform and orderly oil filling holes. Lubricating oil is injected after assembly. The bearing has the advantages of large oil storage, convenient installation, and small design machine, and can replace the copper sleeve to use, greatly reducing the cost
The inner hole of the product is full of and oil pits, which can store a large amount of oil during use and extend the refueling interval.
2. Less oil lubrication, suitable for occasions where it is difficult to add oil or water lubrication;
3. Good wear resistance, low friction coefficient, and long service life;
4. It can be used within the range of -100℃ to 200℃;
5. Good coupling performance, low noise, no pollution;
6. Thin-walled structure, lightweight, can reduce the mechanical volume;
7. The matrix has high density, gas-free shrinkage cavity, and large bearing capacity;
Currently has been widely applied to various mechanical sliding parts, such as automation machinery and equipment (scale, swing, slide, bending, cyclotron, turning parts) of the hydraulic cylinder guide bush, textile machinery, plastic molding machine, die-casting machine, rubber machinery, hydraulic truck, automobile, motorcycle industry, ports, water conservancy, construction, agricultural machinery, etc.

Long service intervals under severe operating circumstances.

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547.

Materials

Wrapped bronze bearings are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.

Lubrication

Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft. For heavily contaminated applications, we recommend sealing off the bearing. This will protect both the bearing and the lubricant.

Advantages

The main advantages of wrapped bronze bearings include:

• Long service intervals
• Not affected by impurities
• Suitable for corrosive environments
• Suitable for impact loads and vibrations at low speeds
• Good heat dissipation

Applications

Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

• Agricultural vehicles
• Lifting gear
• Offshore
• Excavators
