OEX Alternator 12V 180A Bosch Style BXA021

The OEX Alternator 12V 180A Bosch Style is a new rotating electrical unit with a 12 volt output, 180 amp power rating, internal regulator, and pad mount arrangement. It is identified by part number BXA021 and pin code IR161, which are the key checks to confirm before purchase or installation.

This alternator uses a 6 groove pulley with a 50mm outside diameter and is listed at 7.22kg. Those details matter when matching pulley alignment, belt profile, and physical fitment, especially where the original charging unit is being replaced rather than upgraded.

OEX positions this unit as part of its rotating electrical range, with sourcing from original equipment manufacturers and aftermarket suppliers. It is supplied new, not remanufactured, and carries a 3 year passenger / 1 year commercial warranty for peace of mind in the correct application.

Application and Buying Notes

Before ordering, match the part number BXA021 and pin code IR161 against the original alternator on the vehicle. The fitment information supplied for this unit covers multiple makes and model groups, but alternators still need a close check on mount style, pulley section, regulator type, and connector details before installation.

The 12V, 180A specification is important for charging capacity and system compatibility. If the vehicle was fitted with a lower output alternator, the replacement should still be confirmed against the original application details, as the physical design and electrical connection must match as well as the rating.

This unit is listed with a Bosch style design, pad mount, internal regulator, and 6 groove pulley with a 50mm outside diameter. Those are practical comparison points when you are checking the vehicle’s existing unit, belt arrangement, and housing configuration. The 7.22kg weight may also help when comparing a removed part to a replacement.

For commercial use, the warranty is listed as 1 year, while passenger use is listed as 3 years. Warranty coverage still depends on correct application and installation, so it is worth confirming the vehicle details carefully before fitting. If there is any doubt, use the original alternator markings and mounting points as the final check.

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 BXA021 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.

For part number BXA021, 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 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number BXA021, pin code IR161, voltage, mount type, pulley details, and the vehicle application before purchase or installation. If the original alternator differs in any of these areas, do not assume it will be a direct replacement.
