Deep Groove Ball Bearings SKF 6326 M/C3

The SKF 6326 M/C3 single-row deep groove ball bearing, with a 130 mm bore, brass cage and C3 clearance, offers high thermal and mechanical reserves.

The single-row deep-groove ball bearing 6326 M/C3 is one of the most versatile radial bearings for heavy-duty industrial applications. As it is designed as an open bearing, the lubricant reaches the rolling elements and raceways unimpeded. The rings and balls are made from standard rolling-element bearing steel 100Cr6. Thanks to the solid brass cage, this rolling bearing keeps the balls on track even under vibrations or acceleration forces. The tolerance class corresponds to P0/PN or ABEC 1.

What is the 6326 M/C3 deep groove ball bearing suitable for in operation?

This roller bearing is particularly suitable for bearing locations subject to combined radial and axial loads, as well as increased vibration requirements. As the bearing has an open design, it connects directly to the existing oil or grease circulation lubrication systems within the machine housing. The component covers an operating temperature range of -20 to +150 degrees Celsius and is designed for applications with corresponding thermal loads.

What are the advantages of a brass cage and C3 radial bearing clearance?

The combination of the designation letter ‘M’ and the ‘C3’ suffix provides functional reserves for demanding operating conditions. The solid brass cage is characterised by high strength and good emergency running properties in the event of insufficient lubrication. The slightly increased radial clearance (C3) compensates for dimensional changes when the inner ring expands more than the outer ring due to heating. This ensures that the required operating clearance is maintained even under thermal stress and helps to prevent the rolling elements from seizing.
