What Does SKF 6013-2RS1 Mean?

6013 - Bearing Series and Basic Design

The designation 6013 identifies a single row deep groove ball bearing with dimensions of 65x100x18 mm.

In the basic designation:

• 60 identifies the dimensional series.

• 13 is the bore code corresponding to a nominal bore diameter of 65 mm.

The bearing consists of an inner ring, an outer ring, a single row of balls and a cage.

The deep raceway grooves allow the bearing to accommodate radial loads and axial loads acting in both directions.

2RS1 - Two SKF Contact Seals

The suffix 2RS1 identifies two RS1-type contact seals, one fitted on each side of the bearing.

These seals help retain the factory-applied grease and reduce the entry of contaminants into the bearing.

Unlike non-contact metal shields, RS1 contact seals operate with a sealing lip in contact with the mating ring surface.

This provides a different level of contamination protection but also introduces additional friction.

The 2RS1 designation does not mean that the bearing is completely waterproof or suitable for every chemical environment.

CN - Normal Radial Internal Clearance

SKF 6013-2RS1 has normal radial internal clearance, designated CN.

The full bearing designation does not include the C3 suffix.

Radial internal clearance is important because bearing fits and operating temperatures can reduce the clearance available after installation.

Selecting normal clearance or increased C3 clearance must be based on the operating conditions of the specific application.

Cage and Internal Construction

SKF specifies a pressed steel cage for this bearing execution.

The cage maintains the correct spacing between the rolling elements and guides them during rotation.

The bearing is manufactured from bearing steel and belongs to the SKF Explorer performance class.

Construction and Operating Principle

Inner Ring

The inner ring has a cylindrical bore with a nominal diameter of 65 mm.

It is designed to fit onto a shaft with an appropriately selected dimensional tolerance.

The shaft fit affects operating conditions, including the bearing's final internal clearance.

Outer Ring

The outer ring has a nominal outside diameter of 100 mm.

Its raceway guides the rolling elements, while the outside surface fits into the bearing housing.

The overall bearing width is 18 mm.

Balls and Cage

A single row of balls is arranged between the inner and outer rings.

The pressed steel cage maintains the correct spacing between the balls.

The deep groove construction allows the bearing to support radial loads and axial loads in both directions, within the limits established by its load ratings and operating conditions.

Contact Seals on Both Sides

Two RS1 contact seals protect the bearing interior.

Their main functions are to reduce contamination and help retain the lubricant inside the bearing.

The bearing is designed for operation with its factory-applied grease and does not have a standard relubrication feature.

SKF 6013-2RS1 Load Ratings and Operating Speed

Basic Dynamic Load Rating C - 31.9 kN

The basic dynamic load rating is used in bearing fatigue life calculations.

It must not be interpreted as a universal maximum permissible operating load.

Actual bearing life depends on equivalent load, rotational speed, lubrication and operating conditions.

Basic Static Load Rating C0 - 25 kN

The basic static load rating is used to evaluate loading conditions where permanent deformation at the rolling element and raceway contacts becomes relevant.

It is particularly important for heavily loaded bearings, very low rotational speeds or stationary loading conditions.

Fatigue Load Limit Pu - 1.06 kN

The fatigue load limit is a parameter used in SKF bearing life calculation methods.

It is not the maximum permissible force acting on the bearing and must not be interpreted as such.

Limiting Speed - 4,000 rpm

SKF specifies a limiting speed of 4,000 rpm for the 6013-2RS1 bearing.

The actual operating speed must also account for the contact seals, load, temperature and lubricant characteristics.

For high-speed applications, the operating requirements of the complete bearing arrangement must be verified.

Alternative Designations and Reference Numbers

Common written variations include:

• SKF 6013-2RS1

• 6013-2RS1 SKF

• SKF6013-2RS1

• 6013 2RS1 SKF

• 6013 2RS SKF

• SKF 6013 2RS

The designation 6013 2RS is a general commercial description, whereas SKF 6013-2RS1 identifies a specific manufacturer execution.

When ordering a replacement bearing, the complete designation printed on the original bearing or SKF packaging should be checked.

SKF 6013-2RS1 vs Other SKF 6013 Variants

These variants have the same basic dimensions of 65x100x18 mm but differ in sealing arrangements or radial internal clearance.

They are not automatically interchangeable.

SKF 6013-2RS1 vs SKF 6013-2Z

Both bearings have the same basic dimensions but use different protective arrangements.

SKF 6013-2RS1 features contact seals, while SKF 6013-2Z uses non-contact metal shields.

The 2Z design avoids the friction associated with contact sealing lips but provides different protection against contamination.

Selection should consider operating speed and environmental conditions.

SKF 6013-2RS1 vs SKF 6013

SKF 6013 is the basic open bearing configuration.

SKF 6013-2RS1 incorporates two contact seals and factory-applied grease.

An open bearing may operate with an oil or grease lubrication system provided by the surrounding machine design.

Replacing a sealed bearing with an open version requires verification of lubrication and contamination protection.

SKF 6013-2RS1 vs SKF 6013-2RS1/C3

These executions share the same basic dimensions and RS1 contact seal arrangement but differ in radial internal clearance.

• SKF 6013-2RS1 has normal internal clearance, CN.

• SKF 6013-2RS1/C3 has increased radial internal clearance, C3.

Substituting CN with C3, or vice versa, requires checking bearing fits and operating temperature.

Bearing Selection and Interchangeability

Before ordering SKF 6013-2RS1, verify the following requirements:

• Complete SKF designation 6013-2RS1.

• Shaft diameter of 65 mm.

• Housing bore diameter of 100 mm.

• Available installation width of 18 mm.

• RS1 contact seals on both sides.

• Normal radial internal clearance, CN.

• Required dynamic and static load ratings.

• Operating speed.

• Operating temperature.

• Inner and outer ring fits.

• Lubrication requirements.

• Environmental contamination.

• Equipment manufacturer's specifications.

The dimensions 65x100x18 mm establish the basic geometric compatibility but do not guarantee technical interchangeability.

A bearing from another manufacturer may have different seals, cage construction, lubricant or operating parameters.

Applications of SKF 6013-2RS1

SKF 6013-2RS1 is designed for rotating shaft arrangements requiring dimensions of 65x100x18 mm, contact seals on both sides and normal radial internal clearance.
