An oil ring lubricated split bearing housing (21) with labyrinth seal for preventing oil leakage, comprising upper and lower bearing housing halves (22, 23), having mating seat surfaces for a bearing (2) supporting a shaft (1), incorporating, an oil reservoir space (28) in the lower housing half (23), an oil pick up ring (29) partly immersed in the oil space (28) and rotating for transfer of oil from space (28) to bearing (2), an inner labyrinth sealing sleeve (24) fixedly fitted around the shaft (1), and having a circumferential axial groove (27) facing away from the bearing (2), and an outer labyrinth sealing part (30) with a portion (31) projecting axially into the axial groove (27) thereby forming a labyrinth seal, wherein both bearing housing halves (22, 23) have gable openings closely fitting around the sleeve (24), the outer labyrinth sealing part (30) being a separate ring having an axially projecting portion (31) entering in the axial groove (27) and another portion (34) retained in a radial, circumferential groove (33) in the upper bearing housing half (22). |
