Deep Groove Ball Bearings SKF 6411

The SKF 6411 single-row deep groove ball bearing, with dimensions of 55x140x33 mm, offers a robust solution for combined radial and axial loads.

The 6411 deep-groove ball bearing is a single-row radial ball bearing conforming to standard tolerance class P0/PN or ABEC 1. With a bore of 55 mm, an outside diameter of 140 mm and a width of 33 mm, this rolling bearing primarily accommodates radial forces and axial loads in both directions. The rings and rolling elements are made from standard roller bearing steel 100Cr6. As an open bearing without integrated sealing rings, this design is particularly suitable for applications where the lubricant is required to circulate freely.

In which applications is the 6411 deep groove ball bearing used?

Design engineers prefer to use this bearing in shaft mountings subject to combined loads in a protected environment. As the bearing is of an open design, the lubricant reaches the raceways and the sheet steel cage directly. The component is designed for oil- or grease-lubricated housing designs that feature external sealing. The permissible operating temperature range is from –20 to +120 degrees Celsius, enabling the bearing to withstand the thermal demands of continuous industrial applications.

What are the distinctive features of the 6411 deep-groove ball bearing in open design?

This model has standard radial clearance and features a cylindrical outer ring without a flange or groove. The guided sheet steel cage keeps the balls at a uniform distance apart and reduces friction at high speeds. As there are no contact seals to generate frictional heat, the bearing runs smoothly. For the design, this means that you can precisely tailor the external lubricant supply and housing protection to the ambient conditions in order to protect the component from contamination.
