OEX Alternator 24V 55A Bosch Style BXA9019

The OEX Alternator 24V 55A Bosch Style is a new rotating electrical unit supplied under part number BXA9019. It is rated at 24 volts and 55 amps, with an internal regulator and a single leg alternator mount, so it suits applications that call for those exact electrical and mounting details.

This unit is listed as suitable for Bosch applications and includes a mount leg thickness of 80mm, a 10mm pivot hole, a 10mm adjusting hole, and a 180mm mount centre-to-centre measurement. Those dimensions matter when matching a replacement alternator, particularly where the original unit must line up with the bracket and belt drive without modification.

At 5.9kg, with a 17mm shaft diameter, this alternator is a substantial 24V charging component rather than a universal fit item. The warranty is listed as 3 years for passenger use and 1 year for commercial use, which gives a clear reference point for the intended application category and ownership expectations.

Application and Buying Notes

When replacing an alternator, the key checks are voltage, output, regulator type and mounting style. This unit is 24V, 55A, has an internal regulator, and uses a single leg mount, so it is only suitable where those details match the original Bosch-style unit.

The mounting dimensions are just as important as the electrical specification. The listed 80mm mount leg thickness, 10mm pivot hole, 10mm adjusting hole and 180mm mount centre-to-centre measurement should be compared against the removed alternator or the vehicle’s application details before ordering.

The shaft diameter is 17mm and the unit weighs 5.9kg, which further confirms that physical matching should be checked carefully. If the original alternator differs in shaft size, bracket spacing or mounting arrangement, the part may not install correctly even if the voltage rating appears similar.

Fitment coverage is broad across BELL, CATERPILLAR, Daysworth, Maserati, Saab and Scania applications, but that does not replace a direct check. Use the part number BXA9019, the Bosch-style description, and the measured dimensions together to confirm the replacement is correct for the vehicle or machine in front of you.

For commercial or off-road equipment, confirm the charging system requirements as well as the alternator layout. A 24V, 55A unit is not a general substitute for lower-voltage or higher-output systems, and matching the internal regulator arrangement can be important when the original installation is tightly specified.

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 BXA9019 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.

OEX Alternator 24V 55A Bosch Style. Part number BXA9019 should be checked first. Listed voltage is 24. Listed output rating is 55. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA9019, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number BXA9019, 24V output, 55A rating, internal regulator, single leg mount and the listed dimensions against the original unit and application details before purchase.
