Deep Groove Ball Bearings SKF 6300 /C3

The SKF 6300 /C3 deep groove ball bearing (10x35x11 mm) is an open, single-row rolling bearing with C3 clearance, allowing for thermal expansion.

The SKF 6300/C3 deep groove ball bearing is a single-row bearing made from standard roller bearing steel (100Cr6) with a 10 mm bore, 35 mm outer diameter and 11 mm width. As an open design without integrated sealing washers, it allows unhindered access of lubricant within a sealed housing. Designs with rotating shafts benefit from the radial load-carrying capacity and the guidance provided by the sheet steel cage. This component is suitable for drives and gearboxes where operating speeds and thermal influences combine.

What is the 6300/C3 deep groove ball bearing suitable for in industrial plant?

This single-row deep groove ball bearing primarily accommodates radial and moderate axial forces and is best suited for use in protected installations. Typical applications include electric motors, pumps and gearboxes where lubrication is supplied via a central oil circuit or housing grease. As it does not use ablative seals, the bearing operates with minimal frictional resistance. The permissible temperature range is from -20 to +150 degrees.

What does the C3 clearance rating mean for the 6300 deep-groove ball bearing?

The designation C3 indicates a slightly increased radial clearance compared with the standard version. This additional internal clearance between the rolling elements and raceways compensates for dimensional changes when the shaft heats up during operation or when fixed bearing seats cause the inner ring to expand. At normal temperatures without a thermal gradient, standard clearance is often sufficient. Manufactured to tolerance class P0 or ABEC 1, this model meets the standard accuracy requirements of general mechanical engineering.
