OEX Alternator 12V 150A Bosch Style BXA014

The OEX Alternator BXA014 is a new 12V, 150A unit in Bosch style, supplied as an alternator for rotating electrical applications. It is listed with a twin leg alternator mount, 75mm inside mounting legs, and a 128mm mount centre to centre measurement, so those fixing dimensions need to line up with the vehicle application before purchase.

This unit uses an internal regulator and a 6 groove pulley with a 50mm outside diameter. The pivot hole diameter is listed as M10x1.5 / 10, and the adjusting hole diameter is 10, which are important checks when matching the alternator to the original bracket and belt drive layout.

OEX states that its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with ISO9001-certified factories supporting engineering, testing, and quality control procedures. The alternator is a new unit and is backed by a 3 year passenger and 1 year commercial warranty.

For buyers comparing replacement options, the key identifiers here are OEX, part number BXA014, Bosch suit unit make, 12V system voltage, and 150A output. These details are the main reference points to confirm against the original unit and vehicle application before ordering.

Application and Buying Notes

Before ordering, compare the part number BXA014, the Bosch style design, and the listed mounting dimensions against the unit already fitted to the vehicle. The important physical checks are the twin leg mount, 75mm inside mounting legs, 128mm centre-to-centre spacing, M10x1.5 / 10 pivot hole diameter, and 10mm adjusting hole diameter.

The pulley details matter just as much as the electrical rating. This alternator is specified with a 6 groove pulley and 50mm outside diameter, so the belt profile and pulley size need to match the vehicle’s charging system setup. The internal regulator is also relevant because regulator type must suit the vehicle application.

The 12V, 150A specification tells you the electrical capacity of the unit. That does not replace a fitment check, but it is useful when comparing against the original alternator output and system requirements. If the original unit differs in output, regulator arrangement, or mounting style, confirm compatibility before fitting.

This OEX alternator is a new part and weighs 6.66kg, which can help when comparing to a removed unit on the bench. The product is backed by a 3 year passenger and 1 year commercial warranty, but warranty cover does not confirm suitability for a specific vehicle. Application details and the original part number remain the safest checks.

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 BXA014 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. BXA014, Brand OEX, Description OEX Alternator 12V 150A Bosch Style, Adjusting Hole Diameter 10, Pin Code IR168, Power Rating (Amp) 150, Pulley Section 6 Groove, Suits Unit Make Bosch, Alternator Mount Twin Leg.

OEX Alternator 12V 150A Bosch Style. Part number BXA014 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA014, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 2003, BMW 5 2004, BMW 5 2005. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment using part number BXA014, the Bosch style application, and the listed mounting and pulley measurements before ordering. If the original alternator differs in mount style, pulley section, hole size, regulator type, or output rating, check the vehicle application carefully with the removed unit in hand.
