Permissible sliding velocity, v, min. 0, m/s. Permissible sliding velocity, v, max. 2, m/s. Coefficient of friction, µ, min. 0.03.
where v = sliding velocity, m/s n = rotational speed, r/min d = bore diameter of bushing, mm. The specific bearing load can be calculated using p = F / (d ¥ b) where p = specific bearing load, N/mm2. F = bearing load, N d = bore diameter of bushing, mm b = width of bushing, mm. SKF bushings – technical data. Solid. Sintered.
