Deep Groove Ball Bearings FAG 6314 -Z-C3

The 6314 -Z-C3 deep groove ball bearing from FAG Wälzlager features dimensions of 70 x 150 x 35 mm, with a single-sided sheet metal cover and C3 clearance for applications subject to thermal stress.

This single-row deep-groove ball bearing primarily accommodates radial forces as well as axial loads in both directions. The design features a bore of 70 mm, an outside diameter of 150 mm and a width of 35 mm. Manufactured from standard rolling-bearing steel 100Cr6 with a sheet steel cage, the bearing complies with the standard tolerance P0/PN (ABEC 1). A cylindrical outer ring without a flange or ring groove facilitates installation in smooth housing bores.

What is the FAG 6314 -Z-C3 deep groove ball bearing suitable for?

This rolling bearing is primarily used in bearing arrangements operating at medium to high speeds where one-sided protection against the ingress of contaminants is required. The open rear allows lubricant to be applied directly, whilst the cover plate prevents the ingress of particles. The design is suitable for demanding shaft mountings where temperature differences occur during operation.

What are the characteristics of the C3 bearing clearance and the Z cover?

The suffix ‘Z’ denotes a non-contacting cover plate made of sheet steel on one end face. This cover generates no additional frictional torque and keeps mechanical particles out. The designation C3 indicates an increased radial bearing clearance. It compensates for operational thermal expansion between the shaft and housing, as well as constriction caused by tight fits, ensuring that the rolling elements roll freely.
