Abstract: A seal assembly (10, 110) has an inner seal carrier (14, 114) with seals (16, 116, 18, 118), an outer carrier (30, 130) with inner curved surface (144) matching an outer curved surface (146) of the inner seal carrier for angular pitch adjustment of 3° to 5° for the inner seal carrier within the outer carrier, a flexible seal (36, 136) between the outer carrier and the bearing housing (28, 128), and oil within a cavity (20, 120) between the seals, preferably above atmospheric pressure. Shoulder bolts (140) allow lateral movement of the seal assembly with respect to the bearing housing. The seal assembly allows for misalignment and lack of parallelism of the shaft relative to the bearing housing whilst preventing contamination of the bearing.
