Custom Sliding Bushing Design

Metal-Polymer Composite Self-lubricating Bushing Material:

PTFE Sliding Bushings: These bushings are designed for dry operation, featuring a low friction coefficient, reduced wear, and enhanced sliding characteristics. They create a protective transfer film on the mating metal surface, making them ideal for both rotary and oscillating movements.

Composition of Sliding Bushing PTFE Material:

A bronze backing that offers robust load-bearing capabilities and excellent heat dissipation, along with superior corrosion resistance.

A porous bronze sinter layer, measuring 0.20-0.35mm, maximizes thermal conductivity away from the bushing’s surface and acts as a repository for the PTFE/lead blend.

A top layer of PTFE and lead, ranging from 0.01 to 0.03mm, produces an exceptional initial transfer film. This film coats the mating surfaces of the hub assembly, establishing a durable oxide-type lubricating film.

Here you can find everything you need to know about our plain bearings/bushings.
A plain bearing is a shaft bearing that can carry higher loads than a ball bearing.
There are many options in plain bearings depending on the load, speed and environment.

Thin Wall Plain Bearings
Our grooved steel/PTFE oil-free plain bearings are the most common type of plain bearing that can manage high loads and high speeds. As an alternative, you can choose bearings with POM, which can be used for edge loads and dirty environments where lubrication is desired. In outdoor environments, our split bronze bushings with internal grease pockets (FB090) may be suitable. These bearings can manage relatively high loads and should be lubricated regularly.

PTFE plain bearings
A simple type of bearing, but with the same precise adjustment as the others. This is a good choice in applications where forces are low, speeds are low and corrosion is not a problem. Self-lubricating bushings are oil-free, but initial lubrication and periodic relubrication reduce wear and friction. If humidity is high and shaft tolerances have been established, this option has two benefits: lower friction (longer bearing life).

In addition, we also have bronze bushings that can handle relatively high speeds, but with lower loads. Massive bronze bushings for higher loads
Under extreme loads, for example for construction machinery, our plain bearings can be used. Please see our “Plain Bearing Facts” page in the menu below for further information on other plain bearings.

We will be happy to help you with your selection of plain bearings.

Wear resistance

1) “Run together” stage: the surface layer of PTFE mixture to fill the pair surface crater transfer, and the formation of transfer film, at this time, the coefficient of friction is larger, the material wear rate is faster. As shown in the figure Ⅰ curve.

2) “Stable” wear stage: the friction after running together becomes the friction between PTFE, the friction coefficient is low and stable, and the wear rate of the material is low and smooth. As shown in the curve of Zone II.

(3) “Rapid” wear stage: The PTFE lubricant in the pores of the porous layer is consumed, and it is not possible to obtain enough lubricant between the friction interfaces. The friction surface is poorly lubricated, the friction coefficient rises rapidly, and the wear rate of the material accelerates sharply until 70% of the bronze is exposed, and the life is close to termination. As shown in the figure III curve.

The main factors affecting the life span
1) Influence of PV value
The PV value is a valid indicator to determine the wear life of SF-1. If longer life is required, the PV value must be reduced.

2) Influence of ambient temperature
The higher the ambient temperature, the shorter the composite life.
3) Influence on the coupling
The composite bearing service life can be significantly increased when the shaft with alloy steel or hard chromium plating is used for the coupling and the surface roughness Ra=0.4~0.63 range.

In addition to the standard products shown in the catalog, we can also provide non-standard products or order according to customer requirements.

Boundary Lubricated Composite Bearing
Composite type material is filled with tetrafluoro-modified polyacetal plastic as the surface layer of three-layer composite self-lubricating material, it is a benign boundary lubrication material, so it is especially suitable for high load and low-speed rotational motion, swing motion, and often under load opening and closing and not easy to form hydrodynamic lubrication of bearings, thrust washers, sliders, ball seats, and other friction parts. The composite sliding bearing can fully utilize the trace grease, in Boundary lubrication conditions can be long-term without oil maintenance. Under completely oil-free lubrication conditions, POM bushes has low friction performance and allowable PV value, so it is usually rolled out on the plastic surface with oil storage pit and coated with lithium-based lubricating grease or silicone grease during assembly.

Application areas
Pedal assembly, balance bushings, brake calipers, steering main pin bushings and truck tail plate bushings, handlers, cranes, truck-mounted cranes, forest machinery, packaging machinery, construction machinery, hydraulic motors, agricultural machinery mining machinery, metallurgical machinery, water conservancy machinery, steam locomotives, steel rolling industry, etc.

Bearings are an essential component in many machines and equipment, ensuring smooth and efficient operation. Bronze has long been a popular material for bearings, thanks to its excellent wear resistance, high strength, and good thermal conductivity. However, bronze alone may not always provide the necessary performance or durability. That’s where intermediate layers and coatings come in, and one such combination that has proven highly effective is bronze intermediate layer sintered bronze sliding layer PTFE.

Bronze intermediate layer sintered bronze sliding layer PTFE bearings offer many benefits over traditional bronze bearings. The intermediate layer of bronze provides excellent strength and resistance to wear, while the sintered bronze sliding layer offers high porosity and excellent lubrication properties. PTFE (polytetrafluoroethylene), is a highly durable and low-friction material that reduces wear and tear on the bearing.

The bronze intermediate layer provides the necessary mechanical strength to withstand high loads and stresses, while the sintered bronze sliding layer ensures excellent lubrication and low friction, reducing wear and extending the life of the bearing. PTFE is highly resistant to heat, chemicals, and corrosion, making it an ideal material for use in bearings that are exposed to harsh environments.

Bronze intermediate layer sintered bronze sliding layer PTFE bearings are used in a wide range of applications, including in the automotive, aerospace, and industrial sectors. They are commonly used in applications that require high load capacities, low friction, and resistance to wear and corrosion. They are also used in applications that require low noise and vibration, such as in medical equipment and electronic devices.

One of the significant advantages of bronze intermediate layer sintered bronze sliding layer PTFE bearings is their ability to operate at high speeds without overheating or seizing up. The excellent lubrication properties of the sintered bronze and PTFE sliding layer ensure that the bearing stays cool and operates smoothly, even at high speeds.

In addition to their excellent performance, bronze intermediate layer sintered bronze sliding layer PTFE bearings are also easy to install and maintain. They require little to no external lubrication, reducing maintenance costs and downtime. They are also highly resistant to corrosion and wear, reducing the need for frequent replacements.

In conclusion, bronze intermediate layer sintered bronze sliding layer PTFE bearings offer a winning combination of strength, durability, and lubrication properties. They are highly effective in applications that require high load capacities, low friction, and resistance to wear and corrosion. They are also easy to install and maintain, reducing downtime and maintenance costs. When selecting a bearing material, it’s essential to consider the specific application requirements to ensure that the material will perform well under the intended conditions.
