Deep Groove Ball Bearings FAG 626 -2RSR-C3

The FAG 626 -2RSR-C3 deep-groove ball bearing features compact dimensions of 6 × 19 × 6 mm, 2RSR sliding seals and increased C3 bearing clearance for radial loads.

The 626 -2RSR-C3 deep groove ball bearing is a single-row rolling bearing from FAG designed to accommodate radial and light axial forces. Manufactured from standard rolling-element bearing steel 100Cr6 with dimensions of 6 mm bore, 19 mm outer diameter and 6 mm width, this bearing is suitable for compact assemblies. A robust sheet steel cage guides the rolling elements evenly within the raceway. The tolerance class P0 or ABEC 1 defines reproducible fit dimensions for installation and replacement.

What is the 626-2RSR-C3 deep groove ball bearing suitable for?

This deep-groove ball bearing is primarily used in compact shaft designs where contamination and operating temperatures between –20 and +100 degrees occur. This design is suitable for compact bearing arrangements with limited installation space and predominantly radial loads. Thanks to the double-sided sealing, dust and moisture are largely prevented from reaching the rolling elements. The standardised size also facilitates direct replacement during maintenance work.

What are the distinctive features of the 2RSR seal and C3 clearance in the 626 bearing?

When selecting a bearing, the seal design and bearing clearance determine its operational behaviour. The sliding 2RSR seal lips come into contact with the inner ring and retain the grease inside. The slightly increased C3 radial bearing clearance helps to compensate for thermal expansion of the shaft and housing. This ensures that the bearing runs freely even when heated, without any undesirable stress. Before installation, the cylindrical seat with an inner diameter of 6 mm and an outer diameter of 19 mm, without an outer ring flange, must be taken into account.
