High-Pressure-Rated Metal-Bonded Sealing Washers
Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.
Zinc-plated steel washers are corrosion resistant in wet environments. Use these washers under partially threaded nuts or bolts that have a smooth shaft under the head. The Buna-N rubber seal has excellent abrasion resistance and good oil, weather, and chemical resistance. Washers are reusable.

Leveling Washers
Also known as spherical washers, these consist of a male and female washer that, when nested, swivel slightly to compensate for tolerance variations and uneven surfaces. They're good for die and fixturing applications.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Black-oxide steel washers are mildly corrosion resistant in dry environments.

Oil-Embedded Sleeve Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
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.
