OEX Alternator 12V 180A Bosch Style BXA050

The OEX Alternator BXA050 is a new 12V unit rated at 180A, built in a Bosch style with a pad mount and internal regulator. It is a rotating electrical component intended for applications that match the Bosch-style mounting and pulley arrangement, so checking the part number and physical dimensions before purchase is important.

Key mounting details for this alternator include 36mm mount centres A, 52mm mount centres B, 82mm mount leg thickness, and 10.5mm pivot and adjusting hole diameters. The pulley is cogged, and the note supplied with the unit states the pulley suits PLX099, with the drive coupler to be replaced at the time of fitment.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and are made in ISO9001 certified factories with stringent engineering, testing and quality control procedures. This alternator is backed by a 3 year passenger / 1 year commercial warranty, which gives useful support when the application, pulley, and drive coupling are correctly matched.

Application and Buying Notes

Before ordering, compare the part number BXA050 with the alternator currently fitted to the vehicle and confirm the Bosch-style configuration is the correct match. The important physical checks here are 12V system voltage, 180A output, pad mounting, 36mm and 52mm mount centres, and 10.5mm pivot and adjusting holes.

The pulley detail matters as much as the electrical rating. This unit uses a cogged pulley, and the supplied note states the pulley suits PLX099. It also says the drive coupler should be replaced at the time of fitment, so plan for that service item rather than reusing a worn coupling.

A 180A alternator can be a suitable replacement only when the vehicle’s charging system and mounting hardware are intended for that style of unit. If the existing alternator differs in mount leg thickness, pulley section, or regulator type, do not assume it will interchange without checking.

The warranty is 3 years for passenger use and 1 year for commercial use, but that does not remove the need to verify dimensions and application before installation. Correct matching at the bench or on the vehicle is still the safest way to avoid repeat removal and avoidable downtime.

If you are replacing a Bosch-style unit, compare all visible mounting points, the pulley profile, and the drive coupling condition before purchase. The 7.6kg weight, pad mount format, and internal regulator are practical identifiers that can help confirm you are comparing like with like.

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 BXA050 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.
