Deep Groove Ball Bearings SKF 6414 /C3

The SKF 6414 /C3 deep groove ball bearing is an open, single-row rolling bearing with a 70 mm bore, designed for high radial loads and elevated operating temperatures.

The 6414 /C3 deep groove ball bearing is a robust component made from standard rolling-element bearing steel (100Cr6) for demanding industrial applications. The single-row bearing has an outer diameter of 180 mm and a width of 42 mm. As an open design without integrated sealing washers, it allows for flexible integration into existing lubrication systems. A sturdy sheet steel cage guides the rolling elements evenly into the deep raceways of the inner and outer rings.

What is the 6414 /C3 deep-groove ball bearing suitable for?

This rolling bearing primarily withstands high radial loads, but due to its design, it can also handle axial forces in both directions. Typical applications include demanding shaft mountings in general mechanical and plant engineering subject to combined loads. The open design is particularly suitable for enclosed spaces where external sealing is already in place and lubricating oil or grease circulates. The cylindrical outer ring without a flange allows the component to be fitted flush with cylindrical housing bores.

What distinguishes the C3 bearing clearance in the 6414 series?

The suffix C3 denotes a slightly increased radial bearing clearance compared with the standard version. This increased internal clearance is crucial when temperature differences arise between the inner and outer rings during operation. If the shaft heats up more than the housing, the inner ring expands. The C3 bearing clearance compensates for this thermal expansion as well as tighter press fits, without the bearing becoming stressed. With a permissible temperature range of –20 to +150 degrees, the bearing is suitable for thermally stressed industrial applications.
