6203 flanged (collared) ball bearing for pulleys, used on ESS slicers.

• Type: 6203 ball bearing with collar (flanged)
• Standard 6203 dimensions: bore 17 mm, outer diameter 40 mm, width 12 mm
• Compatibility: ESS slicer pulleys

The collar (flange) on the outer ring allows the bearing to be easily mounted and centered in its seat on the pulley, ensuring correct alignment during rotation. On a slicer, the pulley bearings support the shaft that transmits motion to the blade: as they wear, they generate noise, vibration, excessive radial or axial play, and can cause irregular blade operation. Replace them as soon as these symptoms appear, to avoid damage to connected components.
