OEX Alternator 12V 120A Bosch Style BXA063

The OEX Alternator BXA063 is a 12V, 120A unit built in a Bosch style with a twin leg mount. It is listed as a new alternator, with a 55mm pulley outside diameter, 7 groove pulley section, and a pin code of IR50.

Mounting dimensions matter with alternators, and this unit is specified with 83mm inside mounting legs, a 163mm mount centre to centre measurement, a 10mm adjusting hole diameter, and an M10x1.25 / 10 pivot hole diameter. Those figures are the key points to check against the vehicle before ordering.

This alternator is part of the OEX rotating electrical range and is supplied as an each item. It carries the OEX brand, suits Bosch units, and is backed by a 3 year passenger / 1 year commercial warranty.

For buyers comparing replacement alternators, the combination of 12V voltage, 120 amp output, Bosch-style configuration, and the BXA063 part number gives a clear reference point for matching the correct unit to the application.

Fitment guidance

• Fitment is not fully verified here, so confirm the vehicle application against the part number BXA063 and the Bosch-style mounting details before purchase.
• The provided fitment preview references Nissan Navara applications across model years 2015 to 2020, but the exact vehicle variant should still be checked against the alternator dimensions and pulley specification.
• Check that the vehicle uses a 12V Bosch-style alternator with twin leg mounting, 83mm inside mounting legs, and a 7 groove pulley arrangement.
• Use the mount centre to centre measurement of 163mm, the 55mm pulley outside diameter, and the M10x1.25 / 10 pivot hole diameter as the main matching points.

Application and Buying Notes

When replacing an alternator, the safest comparison points are the part number BXA063, the Bosch-style unit make, and the mounting measurements. This alternator is specified as 12V and 120A, so it is important to confirm the vehicle’s charging system requirements before fitting. The twin leg mount, 83mm inside mounting legs, and 163mm mount centre to centre are the sort of details that usually determine whether the unit will physically install correctly.

The pulley details also matter. This unit has a 7 groove pulley section and a 55mm pulley outside diameter, so the belt configuration should be checked against the original alternator. A mismatch here can cause installation trouble or belt alignment issues, even when the electrical rating is otherwise suitable. The pin code IR50 may also be useful when comparing to the existing unit.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That does not replace proper application checking, but it does give useful buying context for owners and workshops looking for a new replacement alternator rather than a remanufactured unit. The weight is listed at 5.5kg, which may also help when comparing against the unit being removed.

For the best result, compare the old alternator with the photos, part number, and the measured mounting points before ordering. If the vehicle has been modified, or if the existing unit has been swapped previously, rely on the physical dimensions and identifiers rather than model name alone. That is especially important with Bosch-style alternators where small differences in mounting or pulley arrangement can change compatibility.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number BXA063 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
