SKF 6005 2RS 25x47x12 mm - Sealed Deep Groove Ball Bearing

SKF 6005 2RS 25x47x12 mm - Sealed Deep Groove Ball Bearing

SKF 6005 2RS 25x47x12 mm is a commonly used trade designation for a sealed single-row deep groove ball bearing from the SKF 6000 series. It has a 25 mm bore, 47 mm outside diameter and 12 mm width. 2RS is commonly used for a bearing sealed on both sides, while SKF uses specific catalogue suffixes such as 6005-2RSH and 6005-2RS1. The exact marking on the bearing should therefore be checked before replacement.

SKF 6005 2RS - Technical Data

SKF confirms the basic dimensions 25x47x12 mm for the 6005 bearing family. However, SKF distinguishes between specific closure variants, so technical parameters that depend on the exact suffix should only be assigned after confirming whether the actual product is, for example, 6005-2RSH or 6005-2RS1.

SKF 6005 Dimensions

The principal dimensions are:

d = 25 mm

D = 47 mm

B = 12 mm

Complete dimensional identification:

25x47x12 mm

The dimensions 25x47x12 mm identify the basic 6005 bearing size, but they do not define the complete bearing execution.

The same basic bearing size can be supplied as an open bearing, with metal shields or with seals.

For correct selection, both the 6005 basic designation and the suffix defining the specific execution should therefore be checked.

What Does SKF 6005 2RS Mean?

6005

6005 is the basic designation of a single-row deep groove ball bearing from the SKF 6000 series.

The bore code 05 corresponds to a nominal bore diameter of:

25 mm

The principal dimensions of the 6005 bearing are:

25x47x12 mm

2RS

2RS is widely used in the bearing trade as a general description for a bearing with seals on both sides.

However, 2RS should not automatically be treated as the exact SKF catalogue suffix.

Depending on the specific SKF product generation and market, exact SKF references can include designations such as:

6005-2RSH

or

6005-2RS1

Therefore, if the physical bearing or its original SKF packaging is marked 6005-2RSH, that complete designation should be used instead of the simplified 6005 2RS description.

This distinction is technically important and also helps search engines, purchasing systems and AI systems identify the exact bearing variant correctly.

SKF 6005 Construction

SKF 6005 is a single-row deep groove ball bearing.

Its basic construction consists of:

• inner ring
• outer ring
• balls as rolling elements
• cage separating and guiding the balls
• closures on both sides in a sealed version

The deep raceway grooves are characteristic of deep groove ball bearings.

This design is intended primarily to accommodate radial loads, while also being capable of accommodating axial loads in both directions within the operating limits of the bearing and arrangement.

Seals on Both Sides

A bearing described commercially as 6005 2RS is closed by seals on both sides.

This should be distinguished from 6005-2Z, where SKF uses metal shields on both sides.

A seal and a metal shield are different closure systems.

A sealed bearing provides a different balance of contamination protection, lubricant retention, friction and permissible speed compared with a bearing using non-contact metal shields.

For this reason, designations such as 2RS, 2RSH, 2RS1 and 2Z should not be used interchangeably without checking the exact SKF reference.

Technical Parameters of SKF 6005-2RSH

If the actual product is specifically marked SKF 6005-2RSH, SKF catalogue data specify:

C = 11.9 kN - basic dynamic load rating

C0 = 6.55 kN - basic static load rating

Pu = 0.275 kN - fatigue load limit

Limiting speed = 9,500 rpm

Mass = approx. 0.081 kg

These values should not automatically be assigned to every bearing sold under the generic description 6005 2RS unless the exact SKF suffix has been confirmed.

C and C0 are standardized bearing rating parameters and should not be interpreted simply as maximum permissible loads for the complete installed bearing arrangement.

SKF 6005 2RS vs SKF 6005-2Z

Both versions have the same principal dimensions:

25x47x12 mm

Their closure systems are different.

6005-2Z uses non-contact metal shields on both sides.

A version commonly described as 6005 2RS uses seals on both sides.

This difference affects bearing construction and can influence friction, contamination protection and permissible operating speed.

Identical dimensions therefore do not mean identical bearing execution.

SKF 6005 2RS vs Open SKF 6005

The basic SKF 6005 is an open bearing.

A version described as 6005 2RS is closed on both sides.

Both share the principal dimensions 25x47x12 mm, but their closure construction and operating characteristics differ.

The required variant should be selected according to the design and operating conditions of the bearing arrangement.

SKF 6005-2RSH vs SKF 6005-2RSH/C3

The suffix C3 has a separate technical meaning.

6005-2RSH identifies a specific sealed bearing execution.

6005-2RSH/C3 additionally specifies C3 radial internal clearance, meaning clearance greater than Normal.

If C3 does not appear in the complete bearing designation, C3 clearance should not be assumed.

Two bearings can therefore have identical dimensions of 25x47x12 mm and the same seal arrangement but still differ in their internal-clearance specification.

The exact marking on the bearing or SKF packaging should always take priority over a shortened trade description.

If the actual product is marked 6005-2RSH or 6005-2RS1, that exact SKF designation should be retained in technical documentation and purchasing records.

Selection and Interchangeability

Before purchasing a 6005 bearing, check:

• complete manufacturer designation
• dimensions 25x47x12 mm
• exact seal or shield arrangement
• required radial internal clearance
• cage requirements where specified
• accuracy requirements where specified
• radial and axial loads
• rotational speed
• operating temperature
• lubrication conditions
• shaft and housing fits
• requirements of the specific machine

It is particularly important to distinguish between 6005-2RSH, 6005-2RS1, 6005-2Z, an open 6005 and variants with additional suffixes such as C3.

A 25x47x12 mm bearing from another manufacturer should not automatically be considered fully interchangeable with an SKF bearing.

Dimensions are only one part of bearing identification.

Typical Applications of the 6005 Design

Single-row deep groove ball bearings from the 6000 series are used in a wide range of rotating assemblies where radial loads and certain axial loads must be accommodated in a compact bearing arrangement.

Sealed versions are used where the bearing arrangement requires the bearing interior to be closed on both sides.

This description does not assign SKF 6005 2RS to any specific motor, gearbox, vehicle or machine without verified OEM or equipment-manufacturer documentation.

Installation and Handling

Before installation, verify the complete bearing designation and inspect the shaft and housing seating surfaces.

Installation should be carried out under clean conditions.

Mounting force should be applied directly to the ring being installed with an interference fit. Force should not be transmitted through the balls and raceways, as this can damage the rolling-contact surfaces.

The seals should be protected from mechanical damage during handling and installation.

The bearing should preferably remain in its original packaging until installation and should be stored in clean, dry conditions.

FAQ - SKF 6005 2RS

What are the dimensions of SKF 6005 2RS?

The basic 6005 bearing dimensions are 25x47x12 mm: bore diameter d = 25 mm, outside diameter D = 47 mm and width B = 12 mm.

What does 2RS mean in SKF 6005 2RS?

2RS is commonly used in the bearing trade to describe a bearing sealed on both sides. For SKF products, however, the exact manufacturer suffix should be checked, for example 2RSH or 2RS1.

Are SKF 6005 2RS and SKF 6005-2RSH exactly the same designation?

No. 6005 2RS is a general trade description, while 6005-2RSH is a specific SKF designation. If the physical bearing is marked 6005-2RSH, the complete manufacturer designation should be used.

Are SKF 6005 2RS and SKF 6005-2Z the same size?

Their basic dimensions can both be 25x47x12 mm, but the closure design is different. 2Z identifies metal shields, while a 2RS description refers generally to a bearing sealed on both sides.

Does SKF 6005 2RS have C3 clearance?

This cannot be determined from the description 6005 2RS alone. If C3 clearance is required, it should be explicitly identified in the complete bearing designation.

Can a 6005 bearing accommodate axial loads?

Yes. A single-row deep groove ball bearing primarily accommodates radial loads but can also accommodate axial loads in both directions within the operating limits of the bearing and arrangement.

Is a sealed SKF 6005 bearing lubricated at the factory?

SKF sealed deep groove ball bearings are supplied with lubricant inside the bearing. However, the exact grease specification should only be stated after the complete SKF reference has been confirmed.

Can a 6005 2RS from another manufacturer replace an SKF bearing?

Full interchangeability should not be assumed from the 25x47x12 mm dimensions alone. The exact seal design, internal clearance, load ratings, speed capability, tolerances and application requirements should also be compared.

SKF 6005 2RS - Key Information

SKF 6005 2RS is a common trade description for a sealed single-row deep groove ball bearing from the 6000 series with dimensions 25x47x12 mm. For exact identification, check the SKF suffix, such as 6005-2RSH or 6005-2RS1, because 2RS is a generic trade description rather than one universal SKF catalogue designation.
