FAG 6208-2RSR-C3 40x80x18 Deep Groove Ball Bearing 2RSR C3

FAG 6208-2RSR-C3 40x80x18 Deep Groove Ball Bearing 2RSR C3

FAG 6208-2RSR-C3 is a single row deep groove ball bearing with dimensions 40x80x18 mm, featuring seals on both sides (2RSR) and C3 radial internal clearance greater than Normal. The 6208 belongs to the widely used 62 series of deep groove ball bearings. This bearing design primarily accommodates radial loads while also being capable of supporting axial loads in both directions.

FAG 6208-2RSR-C3 – Technical Characteristics

FAG 6208 Bearing Dimensions – 40x80x18 mm

The principal dimensions are:

d = 40 mm – bore diameter

D = 80 mm – outside diameter

B = 18 mm – bearing width

Complete dimensional format:

40x80x18 mm

Buyers who know the bearing size rather than its complete designation may search for it as:

40x80x18 bearing

FAG 40x80x18 bearing

6208 bearing 40x80x18

40x80x18 C3 bearing

40mm bore 80mm OD bearing

Dimensions alone, however, do not fully identify this specific FAG bearing. The required 2RSR sealing configuration and C3 internal clearance must also be verified.

Single Row Deep Groove Ball Bearing

FAG 6208-2RSR-C3 is a single row deep groove ball bearing.

Its basic construction consists of:

inner ring

outer ring

one row of balls

and:

a cage separating and guiding the rolling elements.

The deep raceway geometry is characteristic of this bearing family.

Deep groove ball bearings are designed primarily for radial loads, while their raceway geometry also enables them to accommodate axial loads in both directions.

This allows them to operate under radial as well as combined radial and axial loading, provided the operating conditions remain within the limits required for the bearing arrangement.

What Does 6208 Mean?

6208 is the basic bearing designation.

The 62 identifies the dimensional series, while bore code:

08

corresponds to a bore diameter of:

40 mm.

The principal dimensions of a 6208 bearing are:

40x80x18 mm.

However, the basic designation does not define the complete configuration.

For this exact product, the complete designation is:

6208-2RSR-C3.

What Does 2RSR Mean on a FAG Bearing?

The suffix:

2RSR

identifies a bearing sealed on both sides.

The seals help protect the internal rolling-contact area against contamination and help retain lubricant inside the bearing.

This is why the following versions should not automatically be considered identical:

6208

6208-2Z

6208-2RSR

6208-2RSR-C3.

They can share the same principal dimensions but differ in construction and operating characteristics.

6208 2RS vs 6208 2RSR

Many buyers search for this bearing using the simplified designation:

6208 2RS

or:

6208 2RS C3.

For this exact FAG product, however, the complete manufacturer designation is:

6208-2RSR-C3.

2RS is widely used in the bearing market as a general search term for bearings sealed on both sides, while FAG uses the 2RSR designation for this version.

Therefore, searches such as:

6208 2RS C3 FAG

FAG 6208 2RS C3

6208 2RS C3 bearing

may be used by customers looking for this product.

For technical identification and ordering, verify the complete designation:

FAG 6208-2RSR-C3.

What Does C3 Mean on a 6208 Bearing?

The suffix:

C3

specifies radial internal clearance greater than Normal (CN).

C3 does not indicate:

a higher quality grade

or:

a higher precision class.

It defines a specific internal-clearance group.

For this reason, C3 is an important part of the full bearing designation.

Why Is C3 Clearance Important?

The initial internal clearance of a bearing can change after installation and during operation.

Factors influencing operating clearance include:

shaft fit

housing fit

interference mounting

inner-ring temperature

outer-ring temperature

and:

operating conditions.

Therefore, a standard-clearance 6208 bearing should not automatically replace:

FAG 6208-2RSR-C3.

The clearance required for the original bearing position should always be maintained.

FAG 6208-2RSR-C3 vs 6208-2RSR

Both bearings can have the same principal dimensions:

40x80x18 mm

and both can be sealed on both sides.

The difference is the internal-clearance specification.

6208-2RSR-C3 has C3 radial internal clearance greater than Normal.

A 6208-2RSR version without the C3 suffix may have a different internal-clearance group.

Therefore, identical dimensions do not confirm full interchangeability.

FAG 6208-2RSR-C3 vs 6208-2Z-C3

Both variants may have:

40x80x18 mm dimensions

and:

C3 internal clearance.

However, their closure designs differ.

2RSR – seals on both sides.

2Z – shields on both sides.

These versions should not automatically be considered interchangeable without checking the requirements of the original bearing arrangement.

Selection and Interchangeability

When selecting a replacement for FAG 6208-2RSR-C3, verify:

bearing type – single row deep groove ball bearing

bore diameter – 40 mm

outside diameter – 80 mm

width – 18 mm

cylindrical bore

sealing on both sides

C3 radial internal clearance

and:

the operating and mounting requirements of the bearing position.

Matching only the:

40x80x18 mm

dimensions does not confirm complete interchangeability.

6208 2RS C3 FAG – Is This the Same Bearing?

The search phrase:

6208 2RS C3 FAG

is commonly used to describe a FAG 6208 bearing with seals on both sides and C3 internal clearance.

For the product described here, the exact FAG designation is:

6208-2RSR-C3.

Therefore, 6208 2RS C3 can be useful for finding the correct bearing family, but the full manufacturer's designation should be checked before ordering.

6208 C3 Bearing – What Must Be Checked?

Searching for:

6208 C3 bearing

identifies the basic 6208 size and the C3 clearance group, but it does not fully specify the sealing arrangement.

For this product, the complete configuration is:

6208 + 2RSR + C3.

This distinction matters because other 6208 C3 variants can use a different closure configuration.

40x80x18 Bearing – How to Identify the Correct Version

A search such as:

40x80x18 bearing

primarily identifies the principal dimensions.

It does not specify:

manufacturer

sealing configuration

or:

internal clearance.

For the exact product on this page, the complete identification is:
