Deep Groove Ball Bearings FAG 627 -2RSR

The 627-2RSR deep-groove ball bearing from FAG Wälzlager features compact dimensions of 7x22x7 mm and seals that slide on both sides to provide protection for the bearing seats.

This single-row deep-groove ball bearing 627-2RSR from FAG Wälzlager primarily accommodates radial forces as well as axial loads in both directions. The compact main dimensions – with a 7 mm bore, 22 mm outer diameter and 7 mm width – enable slimline designs. As the outer ring is manufactured without a flange or groove, the bearing can be fitted flush into cylindrical housings. The use of 100Cr6 rolling bearing steel for the rings and rolling elements ensures the component retains its dimensional stability. A sturdy sheet steel cage guides the balls evenly along the raceways.

In which applications is the 627-2RSR deep-groove ball bearing used?

This single-row design is particularly suitable for slender shafts and machine components with limited installation space. The 2RSR seal, which seals on both sides, protects the raceways against the ingress of dirt and moisture and retains the lubricant inside the bearing. The component is designed for a temperature range of –20 to +100 degrees Celsius. The absence of electrical insulation makes the bearing ideal for standard applications in general mechanical engineering.

What are the functions of the 2RSR seal and the tolerance class?

The sliding seal fits elastically against the inner ring shoulders and seals the interior on both sides. This eliminates the need for external sealing elements in the housing cover. The bearing has a standard radial clearance and a tolerance class of P0/PN, which corresponds to the ABEC 1 standard. With standard fits, this ensures a balanced operating clearance without excessive preload at normal operating temperatures.
