SKF 6208-2RS1/C3 Dimensions

The principal dimensions are:

d = 40 mm - bore diameter

D = 80 mm - outside diameter

B = 18 mm - bearing width

Complete dimensions:

40x80x18 mm

These dimensions identify the basic 6208 size, but dimensions alone are not sufficient to confirm complete interchangeability.

The following parameters should also be verified:

2RS1 sealing

and:

C3 internal clearance

What Is SKF 6208-2RS1/C3?

SKF 6208-2RS1/C3 is a:

single-row deep groove ball bearing

The bearing uses one row of balls running between deep raceway grooves in the inner and outer rings.

This bearing type is primarily designed to accommodate radial loads, while its deep groove geometry also enables it to accommodate axial loads in both directions within the operating limits of the bearing arrangement.

What Does 6208 Mean?

The basic designation:

6208

identifies the bearing series and size.

For SKF 6208, the principal dimensions are:

40x80x18 mm

The basic designation does not define the complete bearing configuration.

For this exact reference, the important suffixes are:

2RS1

and:

C3

What Does 2RS1 Mean?

The SKF suffix:

2RS1

identifies:

contact seals on both sides of the bearing

The seals help retain lubricant inside the bearing and reduce contamination reaching the rolling elements and raceways.

This configuration is therefore different from:

6208 - open bearing

and:

6208-2Z - bearing with shields on both sides

What Does C3 Mean?

The suffix:

C3

identifies:

radial internal clearance greater than Normal

C3 is not a quality grade or tolerance class.

It refers specifically to the increased radial internal clearance range before mounting compared with a bearing having normal internal clearance.

This is one of the most important selection parameters for SKF 6208-2RS1/C3.

SKF 6208 2RS C3 vs 6208-2RS1/C3

Customers frequently search for this product as:

6208 2RS C3 SKF

or:

SKF 6208 2RS C3

The exact SKF designation for this configuration is:

6208-2RS1/C3

For SEO and technical identification, both forms can be used naturally.

The primary technical entity should remain:

SKF 6208-2RS1/C3

while:

6208 2RS C3 SKF

covers common commercial search intent.

Contact Seals on Both Sides

SKF 6208-2RS1/C3 has:

seals on both sides

Seal type:

contact

The integrated sealing system helps protect the internal bearing components against contamination and helps retain lubricant.

The 2RS1 design should not be confused with:

2Z

which identifies metal shields rather than contact seals.

C3 Radial Internal Clearance

This bearing uses:

C3 radial internal clearance

which means the internal radial clearance is greater than the Normal clearance range.

This distinguishes:

6208-2RS1/C3

from:

6208-2RS1

The two bearings share the same principal dimensions and sealing arrangement, but they do not have the same internal clearance specification.

Sheet Steel Cage

SKF specifies a:

sheet steel cage

for this bearing.

The cage maintains the correct spacing between the balls and guides the rolling elements during operation.

Cage construction forms part of the exact technical specification of SKF 6208-2RS1/C3.

Bearing Steel Construction

SKF identifies the bearing material as:

bearing steel

This applies to the standard bearing construction.

This reference should not be confused with special variants manufactured from stainless steel or supplied with special surface treatments.

Grease Lubrication

SKF 6208-2RS1/C3 is:

grease lubricated

and fitted with integral seals on both sides.

The bearing is supplied as a sealed bearing configuration intended to retain its lubricant internally.

The actual permissible operating conditions remain dependent on speed, temperature, load, mounting and environmental conditions.

SKF 6208-2RS1/C3 Load Ratings

Basic dynamic load rating:

Cr = 32.5 kN

Basic static load rating:

C0 = 19 kN

These ratings apply to the exact SKF bearing configuration.

Load ratings from another manufacturer's 6208 bearing should not be substituted simply because the nominal dimensions are also 40x80x18 mm.

SKF 6208-2RS1/C3 Limiting Speed

The specified limiting speed is:

5,600 rpm

The limiting speed should not automatically be interpreted as the recommended continuous operating speed in every application.

Actual operating speed depends on factors including:

load

temperature

fits

lubrication

and:

operating environment

What Loads Can SKF 6208-2RS1/C3 Accommodate?

As a deep groove ball bearing, SKF 6208-2RS1/C3 can accommodate:

radial loads

and:

axial loads in both directions

within the technical limits of the complete bearing arrangement.

For new machine designs, bearing life, load and operating conditions should be calculated according to the requirements of the application.

SKF Explorer

SKF identifies this reference as:

SKF Explorer

This is part of the manufacturer's performance classification.

When comparing possible replacements, however, the decision should not be based on the Explorer designation alone.

The exact dimensions, sealing, internal clearance, load ratings and operating conditions remain the key selection criteria.

SKF 6208-2RS1/C3 vs 6208-2RS1

Both bearings have:

40x80x18 mm dimensions

and:

2RS1 contact seals on both sides

The difference is radial internal clearance:

6208-2RS1 - standard internal clearance

6208-2RS1/C3 - increased C3 internal clearance

The two configurations should therefore not be treated as identical without checking the requirements of the bearing arrangement.

SKF 6208-2RS1/C3 vs 6208-2Z/C3

Both variants can have:

C3 internal clearance

and share the dimensions:

40x80x18 mm

Their protection systems differ:

2RS1 - contact seals on both sides

2Z - metal shields on both sides

This difference affects bearing operating characteristics and should be considered during selection.

SKF 6208-2RS1/C3 vs Open 6208/C3

The:

6208/C3

version is open.

The:

6208-2RS1/C3

version has contact seals on both sides.

Both share the same basic dimensions and C3 clearance, but differ in sealing configuration and lubrication environment.

2RS sealing

and:

C3 clearance

while differing in:

seal construction

cage

grease

load ratings

limiting speed

internal geometry

Complete technical specifications should therefore be compared before confirming interchangeability.
