A thrust washer for an internal combustion engine may include a body. The body may have a slip surface and a planar contact surface associated with an engine block. The slip surface may have a surface profile the may include at least one ramp section, at least one flat horizontal section, and at least one oil channel. The at least one ramp section and the at least one flat horizontal section may be connected via an asymptotic curve. The at least one ramp section may extend asymptotically toward the at least one flat horizontal section. The at least one ramp section may have an angular length of 45° or less, the at least one flat horizontal section may have an angular length of 45° or less, and the at least one oil channel may have an angular length of 20° or less.
