SKF 6310 50x110x27 mm - Single-Row Deep Groove Ball Bearing

SKF 6310 is a single-row deep groove ball bearing manufactured by SKF, with dimensions of 50x110x27 mm. It belongs to the 63 bearing series and features an open design without metal shields or elastomer seals. The standard SKF 6310 execution has Normal radial internal clearance, CN, a cylindrical bore and one row of balls. It primarily accommodates radial loads and permissible axial loads in both directions.

Technical Specifications - SKF 6310

What Does SKF 6310 Mean?

The designation identifies the manufacturer, bearing type, dimensional series and bore diameter.

SKF - Bearing manufacturer.

6 - Single-row deep groove ball bearing.

63 - Dimensional series of deep groove ball bearings.

10 - Bore code corresponding to a nominal bore diameter of 50 mm.

The absence of a sealing or shielding suffix indicates the open bearing execution.

The absence of C3, C4 or another internal clearance suffix indicates the standard execution with Normal radial internal clearance, CN.

The complete product designation is:

SKF 6310

SKF 6310 Dimensions

The principal mounting dimensions are:

• Bore diameter d: 50 mm.

• Outside diameter D: 110 mm.

• Width B: 27 mm.

Bearing dimensions: 50x110x27 mm.

The 50 mm bore corresponds to the nominal shaft diameter.

The 110 mm outside diameter determines the nominal housing bore size.

The 27 mm width must be considered when positioning the bearing axially within the assembly.

These dimensions are shared by several 6310 bearing variants. Matching dimensions alone therefore do not establish complete interchangeability.

Construction of SKF 6310

SKF 6310 is a non-separable, single-row deep groove ball bearing.

Its principal components include:

• Inner ring with a deep groove raceway.

• Outer ring with a deep groove raceway.

• One row of balls.

• Cage maintaining the spacing between the rolling elements.

The deep groove raceway geometry enables the bearing to accommodate radial loads and specified axial loads in both directions.

The single-row construction provides a compact arrangement for rotating mechanical assemblies.

The bearing is non-separable, meaning that the rings and rolling elements form an assembled unit.

Open Bearing Design - Characteristics

SKF 6310 does not have factory-installed metal shields or elastomer seals.

The open construction allows lubricant to reach the rolling elements and raceways directly.

This design is suitable for bearing arrangements incorporating:

• Oil lubrication.

• Grease lubrication.

• External lubricant supply systems.

• Periodic lubrication maintenance.

The absence of integral seals also means that suitable protection against contamination must be provided when required by the operating environment.

An open bearing should not be considered maintenance-free solely because of its designation.

Normal Radial Internal Clearance - CN

The standard SKF 6310 execution has Normal radial internal clearance, CN.

Radial internal clearance describes the relative radial displacement possible between the bearing rings under specified measurement conditions.

Common radial internal clearance classes include:

• C2 - Clearance smaller than Normal.

• CN - Normal clearance.

• C3 - Clearance greater than Normal.

• C4 - Clearance greater than C3.

Internal clearance can change after mounting because of interference fits and temperature differences between the bearing rings.

The appropriate clearance class must therefore be selected according to the mounting arrangement and operating conditions.

C3 is not automatically superior to the standard CN execution.

Radial and Axial Load Accommodation

SKF 6310 is primarily designed to accommodate radial loads.

Its deep groove raceway geometry also enables it to support permissible axial loads in both directions.

Correct bearing selection requires consideration of:

• Radial load magnitude.

• Axial load magnitude.

• Direction of applied forces.

• Rotational speed.

• Lubrication conditions.

• Operating temperature.

• Shaft and housing fits.

• Required calculated bearing life.

A standard deep groove ball bearing is not designed to compensate for substantial angular misalignment between the shaft and housing.

SKF 6310 vs Other Bearing Variants

SKF 6310 vs SKF 6310/C3

Both executions have dimensions of 50x110x27 mm and an open design.

The difference is radial internal clearance.

SKF 6310 - Normal radial internal clearance, CN.

SKF 6310/C3 - Radial internal clearance greater than Normal.

These variants should not be interchanged without checking mounting fits and thermal operating conditions.

SKF 6310 vs SKF 6310-2Z

Both variants have identical principal dimensions.

SKF 6310 - Open bearing.

SKF 6310-2Z - Bearing with two non-contact metal shields.

The shields help limit contamination and retain grease inside the bearing.

These differences affect lubrication arrangements and protection of the internal bearing components.

SKF 6310 vs SKF 6310-2RS1

Both executions have dimensions of 50x110x27 mm.

SKF 6310 - Open bearing.

SKF 6310-2RS1 - Bearing with two contact seals.

The sealed execution provides different protection against contamination but also introduces additional friction associated with the contact seals.

SKF 6310 vs SKF 6310-2Z/C3

SKF 6310-2Z/C3 features two metal shields and C3 radial internal clearance.

The standard SKF 6310 execution is open and has Normal radial internal clearance.

Identical principal dimensions do not mean that the variants are interchangeable without evaluating the operating conditions.

Alternative Designations and Search References

Common commercial identification variants include:

• SKF 6310

• 6310 SKF

• SKF 6310 50x110x27

• SKF 6310 ball bearing

• SKF 6310 deep groove ball bearing

• SKF 6310 single-row bearing

The manufacturer's basic designation remains:

SKF 6310

Suffixes such as C3, 2Z or 2RS should not be added unless they are present in the actual product designation.

Bearing Selection and Interchangeability

Before purchasing or replacing the bearing, verify:

• Complete manufacturer designation.

• Dimensions 50x110x27 mm.

• Open bearing construction.

• Normal radial internal clearance, CN.

• Required dynamic and static load ratings.

• Permissible rotational speed.

• Lubrication conditions.

• Shaft and housing fits.

• Operating temperature.

• Required bearing service life.

Bearings from different manufacturers with identical dimensions do not necessarily have identical technical characteristics.

Typical Applications of 6310 Series Bearings

Open single-row deep groove ball bearings can be used in rotating assemblies where suitable lubrication and bearing protection are provided.

Typical applications of this bearing design include:

• Industrial machinery shafts.

• Gearbox assemblies.

• Power transmission systems.

• Electric motors with suitable bearing requirements.

• Rotating mechanical systems.

• Production equipment.

These are general applications associated with the bearing type, not confirmed original equipment applications for this specific SKF product number.

Mounting and Operation

Before installation, clean the shaft and housing seating surfaces.

Inspect the mounting surfaces and verify the required fits and alignment.

Mounting force must be applied directly to the ring being installed with an interference fit.

Force must not be transmitted through the balls and raceways.

Because SKF 6310 is an open bearing, suitable lubrication and protection against contamination must be provided.

The lubricant type, lubricant quantity and maintenance intervals should be selected according to the operating conditions of the equipment.

Store the bearing in its original packaging in a clean, dry environment.
