Plain bearings, also known as sleeve bearings or bushings, are manufactured using a variety of materials to suit different applications and requirements. Some common materials used for plain bearings include:
- Bronze: Bronze bearings are popular due to their high strength, wear resistance, and ability to withstand heavy loads. Tin-bronze and lead-bronze alloys are commonly used in bronze bushings.
- Steel: Steel bearings are known for their durability and high load-carrying capacity. They are often used in applications with heavy machinery and equipment.
- Stainless Steel: Stainless steel bearings are corrosion-resistant and suitable for applications where exposure to moisture or corrosive environments is a concern.
- Polymer (Plastic): Polymer bearings, made from materials like PTFE (Polytetrafluoroethylene), nylon, or acetal, offer low friction and are self-lubricating. They are commonly used in applications where low maintenance and quiet operation are essential.
- Composite Materials: Composite bearings combine various materials, such as metal and polymers, to achieve specific performance characteristics, such as high load capacity and low friction.
- Graphite: Graphite is often used as a solid lubricant in plain bearings, improving their self-lubricating properties and reducing the need for external lubrication.
The choice of plain bearing material depends on factors like load capacity, operating conditions (temperature, humidity, and chemical exposure), friction requirements, and maintenance preferences. Each material has its own advantages and limitations, making it essential to select the most suitable material for a given application.
Maintenance-free Plain Bearing Material,

What to look out for when use Composite Plain Bearing
1.Keep the bearing and its surroundings clean bai, even if invisible dust enters the bearing, it will increase the wear, vibration and noise of the bearing.
2. the use of the device should be careful, do not allow strong stamping, do not allow the hammer directly hit the bearing, do not allow pressure transmission through the rolling body.
3. Use appropriate and accurate installation tools, use special tools as far as possible, and make every effort to prevent the use of such things as cloth and staple fibres.
4.to avoid the bearing corrosion, directly take the bearing by hand, to wash the hands of the sweat, and coated with high quality mineral oil before stopping the operation, in the rainy season and summer to pay special attention to rust.However, under certain special operating conditions, the bearing can achieve a better life than the conventional calculation, especially under light loads.These special operating conditions are the appearance damage that may occur when the rolling surfaces (tracks and rolling elements) are effectively separated and restricted by a smooth oil film.In fact, under ideal conditions, the so-called permanent bearing life is possible.
5.Bearing service life, rolling bearing life in revolutions (or the number of hours worked at a certain speed), defined as: within this life, a bearing shall undergo initial fatigue damage (spalling or defect) on any of its bearing rings or rolling body.However, no matter in laboratory experiments or theoretical application, it can be clearly seen that the bearing with the same appearance under the same working conditions has different theoretical life.In addition, there are several different definitions of the “life” of a bearing, one of which is the so-called “working life”, which means that the theoretical life of a bearing that can be reached before damage is caused by wear, damage is usually not caused by fatigue, but by wear, corrosion, seal damage and other reasons.
