The wall thickness selected for the bearing (along with the housing) must be strong enough to support the load while minimizing elastic or thermal deformation that may alter the bearing geometry.

Minimize elastic or thermal deformation that may change the bearing geometry. Thin-walled bearings should be avoided because they may impede heat transfer during bearing operation. There is also a tendency to reduce holding force and increase deformation sensitivity during machining due to thermal growth and mechanical deformation.

Graphite bearing sliding bearing plates are mainly designed for medium and heavy loads at slow and medium speeds. Medium and heavy loads at speed. The maximum load carrying capacity is determined by the bearing material itself. The overall design must take into account the operating speed, unit load, temperature and any other

special considerations that the bearing is subjected to, such as harsh environments.

The PV factor is a tool that defines the operating capacity of any type of Self-lubricating slide bearing plate.

The acceptable PV value for a given application is a function of load, substrate material, lubricant, temperature, service environment and any other relevant factors. General guidance on the relationship between PV and material

A general guide to the relationship between PV and material is provided in the materials table.

P (pressure) is the force (in pounds per square inch) applied to the Self-lubricating slide bearing plate surface.

The area of a sleeve bushing is defined as the diameter X length. For thrust washers and

plates, only the surface area of the Self-lubricating slide bearing plate should be used.

For sliding plates, the speed is the linear velocity of the sliding surface.

The material tables provide normal design limits for various Self-lubricating slide bearing plate materials, but please verify all design parameters with our engineering department for self-lubricating slide bearing plates to ensure satisfactory performance prior to design. Please verify all design parameters with our engineering department to ensure satisfactory performance.

The coefficient of friction for sliding bearing slides used in the recommended PV range will be around 0.15, depending on the coefficient of friction of the lubricant and the operating parameters of the bearing. Therefore, for high temperature service, a design factor of 0.15 is recommended is recommended. A maximum design factor of 0.15 should be considered, unless field service proves a lower value. Unless field service proves a lower value.

Applications requiring a lower factor can usually be accommodated by special designs from our engineering department.

The efforts of our engineering department can usually be accommodated for lower factor applications.

Ideally, a Self-lubricating slide bearing plate and its mating surfaces should always be separated by a film of lubricant.

However, over time, the specified conditions may change due to wear, contamination, elasticity or thermal deformation, resulting in mating surface contact.

Typically, bronze is used as the base material for self-lubricating slide bearing plates. Physical and chemical treatment of bronze is required in situations involving extreme temperatures, environments that are corrosive to bronze, and loads that exceed the compressive strength of bronze.

The application of bronze strength requires the physical and chemical properties of other materials. Substrate materials include stainless steel, ductile iron and tool steel. Selecting the right

Selecting the proper Self-lubricating slide bearing plate and mating surface materials and lubricants is extremely important to obtain long bearing life and maintenance-free operation.

Self-lubricating slide bearing plate life and maintenance-free operation.

However, we recommend that you contact our engineering department for advice on your particular application.

While the physical data shown is of paramount importance in the selection of materials, the following factors

The following factors should be considered and evaluated by the design engineer for the specific application under consideration

• Scratch resistance Corrosion resistance
• Hardness Difference Shear Strength
• Compressive strength Compatibility
• Fatigue strength Environmental effects
• Deformability

These factors should be evaluated for all Self-lubricating slide bearing plate system components

Self-lubricating slide bearing plate recesses are designed to retain and replenish lubricant.

Recesses may be cast or machined into a metal substrate as a round hole or groove. The size, proper

size, proper spacing, and the correct percentage of groove area on a given Self-lubricating slide bearing plate surface must be carefully designed to ensure adequate lubrication of the Self-lubricating slide bearing plate during use.

Careful design is required to ensure adequate lubrication during the functional life of the Self-lubricating slide bearing plateg. Where possible, we recommend the use of grooved recesses. Grooves are by design.

This research and development over many years has provided the optimum lubrication track pattern. This pattern

This pattern ensures continuous lubrication replenishment between the mating surfaces for the life of the Self-lubricating slide bearing plate.

The service life of the Self-lubricating slide bearing plate. The size, shape and geometric position of the oil groove will be determined by the size and shape of the Self-lubricating slide bearing plate and the operating parameters. The size, shape and geometric position of the oil groove will be determined by the size and shape of the Self-lubricating slide bearing plate and the operating parameters to which it is subjected. The plate construction will have blind spots on all lubrication surfaces. Thrust or expansion washers may have oil grooves on one or both surfaces, or “through holes” as required.

Slide bearing sliders are supplied fully machined with proper clearance and tolerances and ready for installation.

Supplied with proper clearances and tolerances and ready to install. No boring, reaming or other operations are necessary before or after assembly.

Boring, reaming, or other operations before or after assembly are unnecessary and should be avoided as they may affect operating efficiency and service life.

The diameter margin (working clearance) is the amount by which the inside diameter of the bearing exceeds the journal diameter after “use”.

The amount by which the inside diameter of the bearing exceeds the diameter of the journal after “compression”. This measurement is

expressed in thousandths of an inch. Axial clearance is an important consideration in any bearing design.

Selecting the correct clearance is an important factor in bearing performance. For special or severe operating conditions, the diameter clearance is designed using

computer-aided techniques that take into account factors such as Hertzian contact stress, mechanical properties and lubrication.

Because the lubricant in self-lubricating plain bearings covers the mating surfaces with a thick lubricating film, greater clearance is required than in bearings with film lubrication. These

clearances do not, however, indicate any looseness. The lubricant coats the journal and bearing walls and fills the clearances, thus providing a satisfactory fit for the assembly.

Clearances must vary with operating conditions. Factors such as speed, load, temperature, size and type of application must be considered. These charts will serve as a guide for most people to select the correct clearance.

Selecting the correct clearance for most applications. For special or unusual cases
