0006200644 - ESAB 6307-2RS Replacement Ball Bearing

Technical Overview of the ESAB DIN625-6307-2RS Ball Bearing

The ESAB 0006200644 is a high-quality deep groove ball bearing conforming to the DIN 625 standard, designated as a 6307-2RS. This component is a critical spare part for the maintenance of industrial machinery, specifically designed to handle the rigors of continuous operation. The bearing features a single row of rolling elements housed within precision-ground raceways, optimized for low friction and efficient power transmission. With an inner diameter of 35 mm, an outer diameter of 80 mm, and a width of 21 mm, it fits a wide range of standard shafts and housings found in welding power sources, wire feeders, and auxiliary equipment.

One of the defining technical characteristics of this unit is the "2RS" suffix, indicating the presence of synthetic rubber seals on both sides of the bearing. Unlike shielded (ZZ) bearings which have small gaps, these contact seals provide a positive barrier against contaminants. This is particularly important in industrial settings where particulate matter is prevalent. The seals also serve to retain the factory-applied lubricant, ensuring the bearing remains properly greased for its entire service life without the need for external maintenance. The steel cage construction ensures structural integrity under load, while the standard radial clearance allows for thermal expansion during operation.

Engineered for reliability, this bearing supports both radial loads and moderate axial loads in both directions. Its compliance with DIN 625 ensures that it meets strict tolerance classes for dimensional accuracy and running precision. Whether used for replacing a worn motor bearing or rebuilding a mechanical assembly within an ESAB welding system, this part delivers the performance required to minimize downtime and maintain equipment efficiency.
