Sleeve bearing

Are you looking for a sleeve bearing with a good chemical resistance? Or are you looking for a sleeve bearing that you can apply in the food industry (FDA)? Then you’ve come to the right address. We have over 25 years of experience in turning plastic flanged sleeve bearings. For specific applications, but also for conditions where usually metal sleeve bushings are applied. Did you know that, in 9 of the 10 cases, plastic can be used as an alternative material?

Why choose a plastic sleeve bearing?

What are the advantages of the application of a plastic flanged sleeve bearing? Plastic sleeve bushings:

  • have a high load;
  • are wear resistant and
  • have low friction.

A high load? Wear resistant? Metal has the same properties. Are you wondering what the advantages of plastic sleeve bushings are compared to metal sleeve bushings? We are happy to give you an overview:

  • the chemical resistance;
  • the applicability in the food industry (FDA);
  • the material is often self-lubricating (with metals this is limited, you always need a lubricant).

Customised sleeve bushing

Ridderflex has over 25 years of experience in machining plastics. We excel in the production of custom-made sleeve bushings. We can produce your sleeve bushing according to your specifications. This can be based on a drawing or model.

Would you like to know if we can produce your flanged sleeve bushing in plastic? Please contact our sales department.

PE, POM or Nylon flanged sleeve bearing

The most frequently used plastics for flanged sleeve bearings are PE, POM and Nylon. PE and POM are slightly self-lubricating materials. When the material requires even better self-lubricating properties, a Nylon sleeve bushing is a better choice.

PTFE, PEEK (bearing grade) or Vesconite® flanged sleeve bearing

In applications with higher temperatures and higher requirements to the chemical resistance, PTFE and PEEK (bearing grade) are the proper choice. Vesconite® flanged sleeve bearings are ideal in extreme dirty or humid conditions.

Below we will explain the key properties of these materials. Of course we are happy to advise you about the possibilities.

PTFEPTFE virgin (PTFE Teflon ®) is physiologically inert and may be used in direct contact with food (FDA). The material excels because of its wide temperature range and good resistance. PTFE virgin has a good chemical resistance. It also has very low friction.
PEEK PVX®PEEK PVX ® is a material specially developed for flanged sleeve bearings. It has a very high temperature and pressure resistance. PEEK PVX® has good mechanical properties and a very good chemical resistance. The material also has a very high tensile strength and is creep resistant. Because of the PTFE additive, PEEK PVX® has good sliding properties. Ridderflex often applies the material in bush bearings in critical applications.
PEEK PTFEPEEK PTFE is also a material specially developed for bush bearings. The material has good mechanical properties and a very good chemical resistance. It also has a very high pressure and temperature resistance. Because of the PTFE additive, PEEK PTFE has good sliding properties. The material also has a very high tensile strength and is creep resistant.
PEEK ARLON ® 1555PEEK Arlon ® 1555 has a very high pressure and temperature resistance. The material also has a high tensile strength and is creep resistant. Because of the PTFE additive, the material has good sliding properties. This makes PEEK Arlon ® 1555 the ideal bearing grade, especially applied in critical applications.
VESCONITE ®Vesconite ® is a ‘wonder material’, specially developed for bearings. Vesconite ® can be applied in extremely dirty, dusty and humid conditions (such as gold and coal mines). The material is developed to rotate without any kind of external lubrication (self-lubricating). Vesconite ® has a long service life. The material has a very high pressure resistance, good wear resistance and low friction. It is also dimensional stable and the material has limited moisture absorption. This makes the material also suitable for applications under water.
