SKF AB4 Alternator Bearing for Commutator End Service

SKF AB4 is an alternator bearing for the commutator end of the alternator, built around precise bearing dimensions for service work on a wide range of import and domestic vehicles. With an inside diameter of 0.315 in, an outside diameter of 0.905 in, and a width of 0.551 in, it is sized for applications that require controlled rotation and low-friction operation.

SKF has a long history in bearing technology, and this AB4 alternator bearing reflects that focus on dimensional accuracy and durability. It is a direct-fit service part for many Honda Civic, Subaru Impreza, and Ford Escort alternator repairs, including Mitsubishi and Mitsuba alternator applications.

Detailed Description

SKF AB4 is engineered as a replacement alternator bearing for vehicles using commutator-end bearing service. The bearing dimensions are critical for proper alternator rebuild work, and this unit is specified at 0.315 in inside diameter, 0.905 in outside diameter, and 0.551 in width. Those measurements make it a practical choice when servicing alternators on vehicles such as the 1995-2012 Honda Civic, 2003-2014 Subaru Impreza, and 1992-1996 Ford Escort.

Compatible vehicle coverage also includes applications such as 2002-2012 Honda CR-V, 2004-2013 Subaru Forester, 2000-2004 Subaru Legacy, 2000-2004 Subaru Outback, and 1990-1997 Ford Probe. The AB4 part number is also used across multiple interchange references, making it easier to match the correct alternator bearing during repair or rebuild work.

What This Part Helps Address

  • Alternator noise from a worn commutator-end bearing
  • Rough or uneven alternator shaft rotation
  • Excess bearing play during alternator rebuilds
  • Charging system issues caused by bearing wear
  • Service needs on Honda, Subaru, Ford, Acura, Suzuki, Kia, Geo, Chevrolet, Mercury, and Nissan alternators

Installation Notes and Tips

Verify the alternator design and bearing dimensions before installation, especially on vehicles with Mitsubishi or Mitsuba alternators and model-year-specific notes. This SKF AB4 bearing is listed for commutator-end use, so confirm the bearing location during teardown and compare the old bearing to the new one before pressing it in.

For fitment examples, this part fits 2003-2014 Subaru Impreza, commutator end; fits 1995-2012 Honda Civic, commutator end; and fits 1992-1996 Ford Escort, commutator end. Additional coverage includes 2002-2012 Honda CR-V, 2004-2013 Subaru Forester, and 1998-2000 Chevrolet Tracker, all at the commutator end.

Quality Assurance

SKF has more than a century of bearing engineering experience, beginning with the first self-aligning ball bearing in 1907. SKF AB4 is manufactured to high quality standards for consistent fit, long service life, and dependable operation in alternator repair applications.
