Deep Groove Ball Bearings SKF 61810

The SKF 61810 deep-groove ball bearing, measuring 50 × 65 × 7 mm, offers a space-saving solution for rotating shafts subjected to radial loads.

This single-row deep-groove ball bearing 61810 from SKF belongs to the thin-section bearing series and is characterised by a particularly narrow cross-section. With a bore of 50 mm and an outside diameter of 65 mm, the component is only 7 mm wide. Manufactured from standard rolling bearing steel 100Cr6, the bearing absorbs radial forces and supports low axial loads in both directions. Thanks to its open design, the bearing is suitable for oil- or grease-lubricated systems.

What are the industrial applications of the 61810 deep groove ball bearing?

Design engineers turn to the 61810 deep groove ball bearing when shaft diameters are large but the radial and axial installation space within the housing remains severely limited. Typical applications are found in general mechanical engineering for shaft mountings with limited radial installation space. The sheet steel cage guides the rolling elements and keeps friction resistance low. The bearing is designed for operating temperatures ranging from –20 to +120 degrees, thereby meeting the standard thermal requirements of industrial drives.

What criteria are important for the open design of the 61810 bearing?

As this model is designed without integrated sealing washers, the selected lubricant reaches the raceways and balls unimpeded. By design, the open version requires a clean housing environment as well as external sealing elements such as shaft seals or labyrinth seals to prevent the ingress of dirt particles. With tolerance class P0/PN or ABEC 1 and standard radial bearing clearance, the bearing complies with current industry standards. The outer ring has neither a flange nor a groove, allowing the bearing to fit flush into cylindrical housing bores.
