The Advantages of Using Lead-free Metal-Polymer Plain Bearing Material Metal-Polymer Bearings in Industrial Applications

low friction bushings

When it comes to industrial machinery, having reliable and efficient bearings is crucial to ensure smooth operation and prevent costly downtime. One type of bearing that has gained popularity in recent years is the Lead-free Metal-Polymer Plain Bearing Material metal-polymer bearing. In this article, we will explore the advantages of using Lead-free Metal-Polymer Plain Bearing Material bearings in industrial applications.

Low friction bushings are mechanical components that are used to reduce friction and wear in various types of machinery. They are typically made from materials such as self-lubricating plastics or composites, and are designed to provide a smooth, low-friction surface for moving parts to slide against.

These bushings are commonly used in applications such as automotive suspension systems, hydraulic cylinders, and industrial machinery. They can help to improve efficiency and reduce maintenance requirements by minimizing the amount of friction and wear that occurs between moving parts.

Low friction bushings are an important component of many different types of machinery, and can help to improve performance, reliability, and durability in a wide range of applications.

What are Lead-free Metal-Polymer Plain Bearing Material Metal-Polymer Bearings?

Lead-free Metal-Polymer Plain Bearing Material bearings are made of a metal backing, usually steel or bronze, that is bonded to a porous layer of polymer material. This polymer layer is impregnated with a solid lubricant, such as PTFE or graphite, that reduces friction and wear. Lead-free Metal-Polymer Plain Bearing Material bearings are known for their excellent load capacity, low friction, and resistance to wear and corrosion.

High Load Capacity and Low Friction

One of the main advantages of Lead-free Metal-Polymer Plain Bearing Material bearings is their high load capacity, which means they can support heavy loads without deforming or failing. This is due to the metal backing, which provides structural support, and the polymer layer, which acts as a cushion and reduces friction. The solid lubricant further reduces friction, making Lead-free Metal-Polymer Plain Bearing Material bearings ideal for high-speed applications where heat and wear are a concern.

Self-Lubricating and Maintenance-Free

Lead-free Metal-Polymer Plain Bearing Material bearings are self-lubricating, which means they do not require external lubrication to operate. The solid lubricant embedded in the polymer layer provides a continuous source of lubrication, reducing the need for maintenance and extending the bearing’s lifespan. This also means Lead-free Metal-Polymer Plain Bearing Material bearings are suitable for use in environments where external lubrication is difficult or impossible.

Corrosion and Wear Resistance

Another advantage of Lead-free Metal-Polymer Plain Bearing Material bearings is their resistance to corrosion and wear. The polymer layer protects the metal backing from exposure to moisture, chemicals, and other corrosive agents, preventing rust and degradation. The solid lubricant also reduces wear, extending the bearing’s lifespan and reducing the need for frequent replacements.

Versatility and Cost-Effectiveness

Another advantage of Lead-free Metal-Polymer Plain Bearing Material bearings is their resistance to corrosion and wear. The polymer layer protects the metal backing from exposure to moisture, chemicals, and other corrosive agents, preventing rust and degradation. The solid lubricant also reduces wear, extending the bearing’s lifespan and reducing the need for frequent replacements.

Lead-free Metal-Polymer Plain Bearing Material metal-polymer bearings offer a range of advantages over traditional metal bearings, including high load capacity, low friction, self-lubrication, corrosion and wear resistance, versatility, and cost-effectiveness. If you are looking for reliable and efficient bearings for your industrial machinery, consider using Lead-free Metal-Polymer Plain Bearing Material bearings to improve performance and reduce downtime.

Life Factors & Sleeve Bushing Application

  1. PV Value:

    PV value is an effective criterion to calculate the service life of sleeve bushing. If there is need to prolong the service Life, PV value must be reduced.

  2. Ambient Temperature: The higher the working temperature is, the shorter the life of the products would be.
  3. Quality of the Mating Surface:Sleeve bushing service life can be obviously prolonged if its mating axis is made by alloy steel or is plated by hard chrome and with surface Roughness Ra=0.4~0.63.

Application: he printing, woven, tobacco and gymnastic machinery, shock absorber etc..

* By combining the metals and the polymers together, its products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with an erosion-prevention layer. Steel backed with copper-plated steel with porous bronze sintered on the steel and (PTFE+Pb) imbedded into the bores of the bronze.
