Notched Washers for Wood
Also called No. 10 Western Timber and Victor washers, these have large ODs to prevent screws from sinking into wood. The notches allow you to temporarily secure them with nails to keep them from rotating during installation.

Leveling Washers for I-Beams
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Hot-dipped galvanized iron washers are corrosion resistant in wet environments.

High-Load Oil-Embedded Thrust Bearings
Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron.
Iron-copper bearings support heavier loads than SAE 863 bronze 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.
