The ESAB Rear Rotor Bearing (0221301826) is a critical replacement component designed specifically for the maintenance and repair of PKB 250 and PKB 400 welding machines. As a genuine OEM part, it guarantees the exact fit and tolerance required to maintain the mechanical integrity of your equipment's motor assembly. In welding operations, the smooth rotation of internal components is vital for consistent wire feeding and stable arc characteristics. Over time, bearings are subject to wear from friction, heat, and continuous rotation, which can lead to noise, vibration, and eventually, total motor failure.
This rear rotor bearing is engineered to withstand the demanding environment of industrial welding. It supports the rear shaft of the rotor, ensuring it spins true without excessive play or resistance. By replacing a worn or seized bearing with this authentic ESAB part, you eliminate the risks associated with aftermarket alternatives that may not meet the specific load and speed ratings of the PKB series. A failing bearing often manifests as a grinding sound or irregular wire feed speeds; addressing this issue promptly with the correct part can save the more expensive rotor or motor assembly from permanent damage.
Installation of the 0221301826 bearing restores the original factory performance of your machine. Whether you are performing routine preventative maintenance or an emergency repair, using genuine ESAB parts ensures that your welder continues to operate at peak efficiency. This component is manufactured to high standards of durability, offering resistance to the dust and thermal cycles common in welding workshops. Trust in the reliability of ESAB engineering to keep your PKB 250 or PKB 400 running smoothly for years to come.
