Description/Basics of plastic washers/plastic sleeves

Sleeves in general, are among the most commonly used machine elements to create a distance between two components. Plastic sleeves and ceramic sleeves offer added value compared to conventional metal collars.

Plastic sleeves and plastic sleeves with a collar have some advantages over their metallic counterparts. In addition to creating and maintaining a distance, they also have an insulating effect. The insulation effect refers to thermal insulation or electrical insulation depending on the material. In addition, their similarity to natural materials is greater than with metal sleeves. As a result, plastic washers and plastic sleeves (depending on the material) expand to the same extent under the influence of heat, such as wood or similar soft materials.

Plastic washers, as well as washers, enable an increase in surface compression. However, their resistance to pressure loads is lower depending on the material selected than that of a similarly large metal washer. For this purpose, the advantage of thermal and electrical insulation effects exists in plastic washers.

MISUMI also offers plastic washers and plastic sleeves with gliding properties. For example, washers and sleeves made of fluoroplastics are suitable for reducing friction resistances in hinge constructions. It should be noted that plastic sleeves do not replace plain bearings.

Polyether ether ketone (PEEK) has excellent thermal insulating properties. Depending on the strength and material composition, PEEK has a melting point of up to 300°C. It is therefore suitable, among other things, for insulating heating and cooling lines, for example. Due to the quality of the surface, the material has particularly good adhesive properties.

Polyacetal, also called POM, is characterized by its very good machinability and excellent mechanical properties. Polyacetal (POM) products are widely used in various branches of mechanical engineering.

At MISUMI you will find washers and sleeves made of various variants of MC Nylon. In addition to the standard version, a conductive and antistatic type is also offered. Thus, MC Nylon can be used in a wide variety of applications.

The different versions and shapes of the plastic washers and plastic sleeves allow utilising them in a wide variety of applications. Thus, plastic washers can be used, for example, as bearing mountings up to the assembly of printed circuit boards.

Application Examples

Plastic sleeve as thermally insulating spacer sleeve
(1) Plastic sleeves, (2) Cylindrical plastic sleeve, (3) Plastic washer, (4) Hexagon socket screws, (5) Washer, (6) Hexagon nut

Plastic sleeve as bearing ring
(1) Plastic sleeve with guide, (2) Rotary shaft, (3) Timing pulley, (4) Ball bearing (5) Bearing with housing, (6) Drive wheel

Frequently Asked Questions (FAQ)

Question:
Do ceramic washers have the same strength as ceramic sleeves?: Answer:
Due to a radial lamination of the ceramic material, ceramic sleeves have a lower compressive strength than ceramic washers (vertically laminated). Detailed information and comparison values can be found here.
Question:
What is the thermal expansion of plastic sleeves and plastic washers?: Answer:
Plastic sleeves and plastic washers react sensitively to fluctuations in ambient temperature. The length of synthetic resin sleeves varies depending in a ratio of up to 1°C = 0.1 mm depending on the temperature . Details on the thermal expansion of other materials available at MISUMI can be found in this PDF.
Question:
Do you have washers made of a material that provide electric insulation?: Answer:
Most plastics have an electrically insulating effect. The level of insulation differs depending on the material. Polycarbonate has a very good electrically insulating effect. In addition to its good electrical insulating effect, it is also superior to most conventional plastics in terms of mechanical aspects.
Question:
Which material is suitable for both low and high temperatures?: Answer:
Polyether ether ketone (PEEK) and polytetrafluoroethylene (PTFE) have an operating temperature of approx. -50°C (PEEK), respectively -40°C (PTFE) and up to +250°C.
