Deep Groove Ball Bearings SKF 6208 /C3

The SKF 6208/C3 deep-groove ball bearing, measuring 40x80x18 mm and featuring increased C3 clearance, ensures reliable operation under thermal expansion.

This single-row deep groove ball bearing 6208 /C3 from SKF primarily accommodates radial forces as well as axial loads in both directions. Thanks to its open design without sealing washers, the component is particularly suitable for environments where an external lubrication system using oil or grease is already in place. Manufactured from standard roller bearing steel 100Cr6 in combination with a lightweight sheet steel cage, it supports low-vibration operation in industrial plants.

In which applications is the 6208 /C3 deep groove ball bearing used?

Design engineers primarily choose this design for bearing locations where higher operating temperatures arise during operation. With a permissible temperature range of -20 to +150 degrees, the design is suited to demanding thermal conditions. As there are no integrated seals to generate frictional heat, the bearing runs with low resistance even at higher speeds. An external housing seal serves to keep out dirt particles.

What are the characteristics of the increased C3 bearing clearance?

The suffix C3 indicates a slightly increased radial bearing clearance as supplied. If the shaft and inner ring heat up more than the surrounding housing during operation, the material expands. The additional bearing clearance compensates for this radial play without the rolling elements becoming jammed or subjected to excessive stress. Combined with the standard tolerance class P0 (ABEC 1), you receive a dimensionally accurate rolling bearing for a precise fit in shaft seats.
