Introducing TOK’s special function bearings. (Chemical resistance/ conductivity, etc.)

   Contents:

1. Chemical resistant bearings (PK/PE series)

2. Conductive bearings (ER series)
3. Non-magnetic bearings (C series)
4. Rust-resistant bearings(S/SS series)

TOK offers 4 types of special bearings that are chemical resistant, conductive, non-magnetic, and rustproof.

You can select the most suitable bearing for your application.

1. Chemical resistant bearings (PK/PE series)

In environments to chemicals, such as cleaning with chemicals, plating, etching, and chemical treatment, metal bearings can have problems with corrosion.

In the PE/PK series, the outer races, inner races, and balls are made of plastic, so they are less likely to deteriorate due to chemicals.

There are many types of plastic materials, each with different chemical resistance, so we will select the most suitable bearing and material according to the chemicals used.

Application examples : Cleaning machines (Glass/Film cleaning, Semiconductors, Electronic-related equipment, etc.)

2. Conductive bearings (ER series)

As plastic is an insulator, some plastics may be prone to static electricity.

The ER series, with its good conductivity and anti-static properties, protects your applications by preventing the adsorption of dust and other debris such as paper dust.

Application examples : High-speed scanners, Guide rollers

3. Non-magnetic bearings (C series)

The C series has excellent non-magnetic and chemical resistance, because its components are made of ceramic.

For example, MRI machines in hospitals use powerful magnets to examine the inside of the body, so magnetic materials cannot be used in the machine itself, and they always check to see if the patient is not wearing any precious metals.
This is where non-magnetic bearings (C series) come in handy.

Application examples : Hospital inspection equipment, Measuring instruments

4. Rust-resistant bearings(S/SS series)

Since all the components are made of stainless steel, 
there is no cause for concern about rusting or corrosion even in environments where the product is exposed to water, seawater, or steam.

In environments where normal metal bearings cannot be used or are difficult to use, rust-proof bearings (S/SS series) can be used to increase the life of your applications.

In addition, S series bearings can be used without grease, so there is no need to worry about grease flowing out even when exposed to moisture, liquid, or steam.

Application examples: Special pumps, Fountain-related equipment
