Maintenance Free Bearings

Types of Maintenance Free Bearings on the Market

To maximise productivity and minimise operating costs, maintenance free bearings are the solution. Industrial plant maintenance departments can save a great deal of time by investing in self-lubricating bearings. Bearing lubrication technology has brought about many changes and advancements to traditional bearing lubrication techniques practiced in industrial plants.

There are 3 main types of maintenance free bearings available on the market. Let’s take a closer look at these:

  • Oil-filled sintered bronze bearings – these first came into production in the early 1930s. Capillary action creates a lubricating oil film on the bearings. These bearings offer a wealth of benefits, including high-precision, impressive rotational speeds and a low co-efficient of friction.
  • Self-lubricating metal-polymer bearings – these first came into production in 1950. These consist of a PTFE polymer liner and a metal backing. The lubricant is transferred from the liner onto the shaft during the movement of the bearing. These bearings offer a low co-efficient of friction, high-load capacity and the ability to operate efficiently in high temperatures.
  • Lubrication-free solid polymer bearings – these first came into production in the 1960s. These bearings typically consist of a combination of solid lubricant, reinforcing fibres and thermoplastic materials.

When looking for the right maintenance free bearings for your application, there are a few factors that will affect your choice. For instance, the wear rate and operation of a bearing under particular loads, speeds and temperatures are important considerations. How the bearing performs in the presence of chemicals, dust or dirt will also help you to decide which ones are best suited to your application.

Self-lubricating maintenance free bearings are used readily in the mining, iron, steel, petrochemical, marine, automotive, civil and materials handling industries.
