SELF ALIGNING BEARING
ERL’s OBA utilizes a self-aligning Ball Bearing. This style of Ball Bearing has a spherical outer race that allows for small amounts of angular misalignment of the shaft relative to the housing. This reduces friction and heat at high speeds. It also puts less bending load on the shaft, increasing life.

TIRED OF REPLACING MECHANICAL SEALS?
ERL’s OBA gives support to the pump shaft directly above the mechanical seal. This greatly reduces the stress on the mechanical seal from vibration caused by the diesel engine and pump. The result is a longer lasting mechanical seal and less maintenance.

100% STAINLESS BEARING HOUSING
ERL's OBA Housing is completely constructed of 300 series stainless steel for long life. CNC machined bearing bore has a tolerance of +_.0004" for exceptional fit. This allows the spherical bearing to accommodate slight misalignment in the pump shaft while maintaining support for the mechanical seal.

ALIGNMENT LIP
ERL aligns the OBA with the mechanical seal through a male snap fit. This ensures the OBA gives the mechanical seal the support it needs for the longest life possible.

TIRED OF REMOVING MECHANICAL SEALS PAST BURRS?
ERL utilizes Timken’s Shaft Guard technology which prevents the set screw from damaging the shaft. This ensures the OBA and mechanical seal are easily replaced without sliding over a burr. Each set screw transfers pressure to the shaft through a stainless-steel hardened band. This eliminates direct shaft-setscrew contact. Truly a first in the commercial marine industry.
