AMES Self-Lubricated Bronze Gleitlager (Sliding Bearings) are high-performance bearings designed to provide smooth and reliable operation with minimal maintenance requirements. These bearings are made from a bronze alloy that incorporates self-lubricating properties, allowing them to operate effectively without the need for external lubricants.
The bronze alloy used in AMES Self-Lubricated Bronze Gleitlager is chosen for its excellent wear resistance, strength, and corrosion resistance. The self-lubricating properties are achieved through the incorporation of solid lubricants into the alloy matrix. These lubricants are evenly distributed throughout the bearing material, providing a continuous lubricating film between the bearing and the mating surface.
The self-lubricating nature of AMES Self-Lubricated Bronze Gleitlager eliminates the need for periodic relubrication, significantly reducing maintenance costs and downtime. The bearings are also designed to withstand high loads and impacts, ensuring long-term reliability and durability in various industrial applications.
AMES Self-Lubricated Bronze Gleitlager are suitable for use in a wide range of environments, including those with high temperatures, high humidity, or exposure to chemicals and corrosive agents. The bronze alloy's corrosion resistance ensures that the bearings can maintain their performance even in harsh conditions.
Overall, AMES Self-Lubricated Bronze Gleitlager offer a cost-effective and reliable solution for applications requiring smooth and maintenance-free bearing operation. Their self-lubricating properties, durability, and corrosion resistance make them an excellent choice for various industrial applications.
Our Bronze Bushings are machined from C93200 (SAE 660
bronze bearing, using the casting process, and then another layer on copper base bronze, bronze powder, spherical bearing rotation, thus formed in the surface of a gap and lubricating oil or grease can form good oil film, the particles produced by the rotation can be very good in the gap, so as to achieve lower PV value, with good oil, can achieve low cost, the characteristics of free maintenance.
Bronze bushing machining provides an easy and economical way to use bearings with tall bearings, good corrosion resistance, dimensions and other performance for any process.
Meanwhile, we can provide different grades of copper alloy according to different conditions, and according to the processing requirements of different shapes, it has higher precision than size grade copper rolling bearings.

The constant presence of oil eliminates the risk of seizure and allows the bearing to work for thousands of hours without wear.
It does not require maintenance, does not require lubricants.
Able to work with loads up to 10 MPa and speeds up to 8 m / s.
The maximum working PV is in the range of 10 MPa · m / s, but can be exceeded in special cases.
The dimensional accuracy is very high (up to IT 5 in diameter) and produces extremely low noise.
The choice of impregnating oil is the key to the bearing function.
Viiplus has a variety of properties of oils (mineral and synthetic) that can operate at temperatures from -60 ° C to +230 ° C.
Another important parameter of this oil viscosity is specially selected for the working lead and speed to enable the bearing to operate under hydrodynamic conditions, thus minimizing the coefficient of friction.
Viiplus also provides specific solutions when oil is in contact with certain types of seals, or for use in food applications.
