Deep Groove Ball Bearings FAG 6307 -Z-C3

The FAG 6307 -Z-C3 deep-groove ball bearing, measuring 35 x 80 x 21 mm, with a single-sided sheet metal cover and C3 clearance, offers stable operation under thermal stress.

The FAG 6307 -Z-C3 deep groove ball bearing is a single-row rolling bearing designed for industrial drives and mechanical assemblies. Featuring an inner ring with a 35 mm bore, an outer diameter of 80 mm and a width of 21 mm, this bearing type primarily accommodates radial forces and moderate axial loads. Manufactured from standard roller bearing steel 100Cr6, the assembly is characterised by high dimensional stability under load.

In which applications is the 6307 -Z-C3 deep groove ball bearing used?

Design engineers primarily use this bearing in rotating shaft assemblies subject to combined radial and axial loads. Thanks to the sheet steel cage, the bearing guides the rolling elements with low vibration at medium to high speeds. The single-sided sheet metal cover keeps coarser dirt particles out from one side. At the same time, the opposite side remains open, which facilitates the supply of lubricant directly from an oil bath or gearbox housing.

When is the combination of a Z-cover plate and C3 bearing clearance appropriate?

The C3 specification denotes a slightly increased radial bearing clearance compared with the standard version. If temperature differences arise between the shaft and the housing during operation, the material expands without the bearing becoming stressed. Tight fits on the shaft also reduce bearing play during press-fitting. Together with the non-contact Z-seal, which does not generate any additional frictional heat, the smooth running of the shaft is maintained.
