0152475035 - ESAB Grease Nipple for PKB 250/400 Wire Feeder Motor

Essential Maintenance for ESAB Equipment

The ESAB Grease Nipple (Part Number 0152475035) is a specialized replacement component engineered for the maintenance of ESAB PKB 250 and PKB 400 series welding machines. Specifically associated with the motor (MOT) assembly, this small but vital part plays a significant role in the longevity and performance of your wire feeding mechanism. In industrial environments, welding equipment is subjected to harsh conditions, including dust, metal shavings, and thermal cycling. The grease nipple serves as the primary access point for introducing lubricants into the sealed bearings or gears of the motor assembly, ensuring that friction is minimized and mechanical wear is kept in check.

Using genuine ESAB parts for maintenance is critical for preserving the integrity of the machine. While generic fittings exist, the specific thread pitch, length, and pressure rating of the 0152475035 are designed to match the tolerances of the PKB series housing perfectly. An ill-fitting nipple can lead to grease leakage, stripped threads, or the introduction of contaminants into the sensitive motor components. By utilizing this OEM part, maintenance teams can ensure that the lubrication pathway remains secure and effective, allowing for precise delivery of grease during scheduled service intervals.

Regular lubrication via this grease nipple helps prevent the seizing of internal components, which is a common cause of wire feed irregularity and motor burnout. For facility managers and maintenance technicians, keeping a stock of these low-cost, high-impact consumables is a best practice that supports continuous uptime. Whether you are refurbishing an older PKB unit or performing routine preventative maintenance, this grease nipple is the correct specification for the job, ensuring your ESAB equipment continues to operate at peak efficiency.
