Deep Groove Ball Bearings FAG 61819 -2RSR

The FAG 61819 -2RSR deep-groove ball bearing combines a slim 95 x 120 x 13 mm cross-section with contact seal protection on both sides for compact shaft mountings.

The 61819 -2RSR deep groove ball bearing is a single-row rolling bearing from the particularly narrow 618 series. With a 95 mm bore, an outer diameter of 120 mm and a width of just 13 mm, this design enables space-saving bearing arrangements. Manufactured from standard roller bearing steel (100Cr6), the bearing accommodates both radial and axial forces. Thanks to its slim design, it is particularly suitable for applications where limited radial installation space and low weight are crucial.

What are the industrial applications of the 61819-2RSR deep groove ball bearing?

Design engineers and maintenance technicians use this thin-section bearing primarily in assemblies with very limited installation space. Typical applications include large-diameter shaft bearings with a low radial height. The RSR seals on both sides protect the raceways from the ingress of dust or moisture. As the rolling elements are guided by a sturdy sheet steel cage, the bearing operates quietly and smoothly even during continuous movement.

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

The -2RSR design features sealing discs made of elastomeric material that make contact on both sides. This contact seal helps to prevent lubricant loss and keep out foreign particles. Thanks to the standard radial bearing clearance and the standard tolerance class P0/PN (corresponding to ABEC 1), the unit can be fitted directly into standard-compliant housings. The permissible temperature range is from -20 to +100 degrees Celsius. For applications involving extreme heat generation, alternative seal designs should be considered.
