Self-Aligning Ball B. SKF 2310

The SKF 2310 self-aligning ball bearing, measuring 50x110x40 mm, compensates for misalignment and accommodates radial and low axial loads.

The 2310 self-aligning ball bearing is a double-row rolling bearing with a common hollow-spherical raceway in the outer ring. This design enables the two rows of balls to automatically compensate for misalignment and shaft deflection during operation. Manufactured from standard rolling-bearing steel (100Cr6), this open bearing features a dimensionally stable sheet steel cage. With a bore of 50 mm, an outer diameter of 110 mm and a width of 40 mm, the SKF version covers an operating temperature range from –30 to +150 degrees Celsius.

What loads and misalignments can the 2310 self-aligning ball bearing accommodate?

The 2310 self-aligning ball bearing is primarily used in applications involving shaft deflection under load or where there are manufacturing-related misalignments between the bearing locations. Typical applications include shaft support arrangements over longer spans and in separately mounted housing configurations. The double-row bearing primarily accommodates radial forces and handles low axial loads in both directions. The angularly adjustable design of the raceways reduces additional internal stresses should components shift slightly during operation.

What are the key considerations for the open design of the 2310 bearing?

As an open model without integrated seals, the 2310 self-aligning ball bearing requires a clean housing environment and external sealing elements, such as shaft seals, to prevent the ingress of contaminants. Grease or lubricating oil can be applied directly to the rolling elements from the outside, allowing for the selection of an application-specific lubricant. With tolerance class P0/PN (ABEC 1) and standard radial clearance, the component fits into standardised machine fits.
