Deep Groove Ball Bearings SKF 6319 /C3

The SKF 6319/C3 deep-groove ball bearing, with a 95 mm bore and increased bearing clearance, offers reliable running characteristics for demanding radial loads.

This single-row deep groove ball bearing 6319 /C3 primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling bearing steel 100Cr6, the open bearing is characterised by high dimensional stability. A sheet steel cage guides the rolling elements evenly into the deep raceways. Thanks to its open design, lubricant reaches the contact surfaces unhindered, enabling a wide operating temperature range between –20 and +150 degrees.

In which applications is the 6319/C3 deep groove ball bearing used?

This design is primarily used in bearing arrangements subject to high radial forces and axial guidance forces, where elevated operating temperatures or temperature differences between the shaft and housing may occur. The open design requires a clean housing environment or external shaft seals. It allows for both oil and grease lubrication. Thanks to its key dimensions – a bore of 95 mm, an outside diameter of 200 mm and a width of 45 mm – the 6319 series is designed to withstand high mechanical loads.

What does the C3 bearing clearance mean for this open roller bearing?

The suffix C3 indicates an increased radial clearance compared to the standard. This additional clearance between the rolling elements and raceways compensates for thermal expansion when temperature differences arise between the inner and outer rings during operation. Even with tight fits on the shaft or in the housing, the C3 clearance helps to prevent the bearing from seizing. The manufacturing accuracy corresponds to tolerance class P0/PN or ABEC 1.
