OEX Alternator 12V 130A Bosch Style BXA018

The OEX Alternator BXA018 is a new 12V, 130 amp unit in Bosch style, supplied as a single-leg alternator with a 6 groove pulley. It is listed with an internal regulator, a 52mm pulley outside diameter, and a 56mm mount leg thickness, so matching the physical layout matters as much as the electrical rating when checking replacement suitability.

This alternator is sold as each unit and carries a 3 year passenger / 1 year commercial warranty. The stated part number is BXA018, with pin code IR189, and the mount centre-to-centre measurement is 156mm with an 11mm adjusting hole diameter. Those details are useful when comparing against the original unit already fitted to the vehicle.

OEX describes this product as being sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factories used for engineering, testing and quality control procedures. For buyers, the important point is still to verify the alternator shape, connector arrangement, pulley type, and mounting dimensions before ordering, especially when the vehicle has previously been repaired or converted.

At 12 volts and 130 amps, this alternator suits applications where the charging system must match the original specification closely. The product is listed under rotating electrical and alternators, and the Bosch-style design should be checked against the removed unit rather than assuming any one vehicle model is covered just by the badge name.

Application and Buying Notes

When replacing an alternator, the safest check is the part number and the physical match. This unit is identified as BXA018 and is a Bosch-style, single-leg alternator with a 6 groove pulley, internal regulator, 156mm mount centre-to-centre measurement, 56mm mount leg thickness, and 11mm adjusting hole diameter. Those points should line up with the removed unit, not just the vehicle make and model.

The 130A output and 12V rating need to suit the vehicle’s charging system requirements. A higher or lower output alternator can cause installation issues or charging concerns if it does not match the original specification. If the existing unit is available, compare the pulley section, pulley outside diameter, connector pin code IR189, and mounting points before purchase.

This alternator weighs 7.48kg and is supplied new. The warranty is listed as 3 years for passenger use and 1 year for commercial use, so the intended application type matters. Commercial vehicles, fleet use, and passenger vehicles can fall under different warranty terms, so it is worth confirming the intended use before fitting.

Fitment references are helpful, but they are not a substitute for checking the exact unit on the vehicle. Bosch-style alternators can vary in mounting ear thickness, pulley configuration, regulator arrangement, and connector layout even within similar model families. Use the specification list to confirm the replacement matches the original alternator as closely as possible.

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 BXA018 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.
