Deep Groove Ball Bearings SKF 6012 -2RS1/C3

The SKF 6012 -2RS1/C3 deep groove ball bearing, measuring 60x95x18 mm, with seals on both sides and a C3 clearance, offers reliable protection against dirt particles.

The single-row deep-groove ball bearing 6012 -2RS1/C3 primarily accommodates radial loads and also supports axial forces in both directions. SKF manufactures this model in the Explorer performance class from standard rolling-element bearing steel (100Cr6) with a sheet steel cage. As it is manufactured to tolerance class P6 (ABEC 3), the component offers defined dimensional and runout accuracy. The factory-applied grease and the double-sided sliding seals ensure the unit is ready for installation and maintenance.

For which operating conditions is the 6012-2RS1/C3 deep-groove ball bearing designed?

This design is suitable for bearing locations where rotating components need to be protected from particles or moisture. The combination of radial load capacity and axial load capacity on both sides allows the bearing to be used in a wide range of industrial applications. Thanks to the slightly increased radial clearance (C3), the bearing compensates for operational heating. The cylindrical outer ring has no flange or groove and fits into corresponding housing bores with a diameter of 95 mm.

When is the combination of C3 bearing clearance and 2RS1 seals recommended?

This combination is recommended when operating temperatures in the bearing assembly range between –20 and +120 degrees, or when tight fits are selected for the shaft and housing. The C3 bearing clearance compensates for thermal expansion and maintains the necessary operating clearance. The 2RS1 seal lips, which grind against the inner ring on both sides, keep the grease inside and protect the raceways from contamination; however, they generate a slightly higher friction torque than non-contacting cover plates.
