About Washers

These are among the most heat resistant plastic washers we carry. All have good chemical resistance.

PEEK washers have excellent tensile strength for high-stress applications. Carbon-filled PEEK washers are stronger and more moisture resistant than PEEK washers.

Metric High-Temperature Plastic Washers

Able to withstand temperatures as high as 450° or 500° F, these are among the most heat resistant plastic washers we carry. They have good resistance to moisture and chemicals.

PEEK washers have excellent tensile strength for high-stress applications.

Carbon-filled PEEK washers are stronger and more moisture resistant than PEEK washers.

Chemical-Resistant Dry-Running Thrust Bearings

These bearings stand up to a wider range of chemicals than other dry-running thrust bearings. They are lightweight and strong.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Air Nozzles

These nozzles are engineered for the most efficient air consumption. Volume (dB) is measured 3 ft. from the nozzle at 80 psi.

Nozzles that meet OSHA 1910.242(b) conform to requirements for maximum air outlet pressure.
