Deep Groove Ball Bearings SKF 6312 -RS1

The 6312-RS1 deep groove ball bearing from SKF Rolling Bearings is a single-row ball bearing with dimensions of 60 × 130 × 31 mm and a single-sided contact seal.

The 6312-RS1 deep groove ball bearing from SKF is a single-row bearing designed to withstand high radial loads as well as axial loads acting in both directions. With a bore of 60 mm, an outside diameter of 130 mm and a width of 31 mm, this size is widely used in industrial mechanical engineering. Manufactured from standard roller bearing steel (100Cr6), this model is characterised by dimensional accuracy in tolerance class P0/PN or ABEC 1. A sturdy sheet steel cage guides the rolling elements smoothly at temperatures ranging from –20 to +120 degrees Celsius.

What loads and mounting conditions can the 6312 -RS1 deep groove ball bearing handle?

The 6312 -RS1 deep-groove ball bearing is primarily used in industrial shaft mountings where radial forces and axial forces acting on both sides are present. Thanks to its design with deep raceways, the component absorbs these combined forces and guides the shaft accurately. The single-row design without a groove in the outer ring allows for straightforward installation in cylindrical housing bores. Both maintenance engineers carrying out repairs and design engineers opt for this design when a single-sided sealed bearing arrangement is required.

What function does the single-sided RS1 seal fulfil in the design?

The single-sided RS1 seal protects the bearing housing at one end face against dust and splash water. At the same time, the opposite side remains open. This facilitates the supply of lubricant via the machine housing or connection to an existing oil circuit. When planning the installation, you should also take the standard radial bearing clearance into account. This standard range ensures smooth concentricity without distortion under normal fits and operating temperatures.
