SKF 6206-2RS1 C3 30x62x16 Deep Groove Ball Bearing

SKF 6206-2RS1 C3 30x62x16 Deep Groove Ball Bearing

SKF 6206-2RS1 C3 is a single-row deep groove ball bearing manufactured by SKF, measuring 30x62x16 mm. It has a 30 mm bore, 62 mm outside diameter and 16 mm width. The 2RS1 suffix identifies contact seals on both sides, while C3 specifies radial internal clearance greater than Normal.

The official SKF designation is:

6206-2RS1/C3

For this exact SKF reference, the basic dynamic load rating is 20.3 kN, the basic static load rating is 11.2 kN, and the limiting speed is 8,000 r/min.

SKF 6206-2RS1 C3 - Characteristics

SKF 6206-2RS1/C3 is a single-row deep groove ball bearing from the 62 dimension series.

Its construction uses one row of balls running in deep raceway grooves in the inner and outer rings.

This geometry is designed primarily for radial loads while also allowing the bearing to accommodate axial loads in both directions within the operating limits of the bearing.

Two suffixes are particularly important when identifying this exact version:

2RS1 - contact seals on both sides

C3 - radial internal clearance greater than Normal

These features should not be omitted when selecting a replacement.

SKF 6206-2RS1 C3 Dimensions

The principal dimensions are:

d - Bore diameter: 30 mm
D - Outside diameter: 62 mm
B - Width: 16 mm

Complete dimensions:

30x62x16 mm

For this bearing, the third dimension is correctly identified as bearing width:

B = 16 mm

The bearing has a:

cylindrical bore

Bearing Construction

SKF 6206-2RS1/C3 is a:

single-row deep groove ball bearing

The confirmed construction includes:

Number of rows: 1
Bore type: Cylindrical
Sealing: Both sides
Seal type: Contact seal
Radial internal clearance: C3
Cage: Sheet metal
Bearing material: Bearing steel
Lubricant: Grease

The bearing is supplied as a sealed, grease-lubricated unit.

SKF product data do not specify a relubrication feature for this version.

What Does 2RS1 Mean?

The SKF suffix 2RS1 identifies a bearing equipped with contact seals on both sides.

The seals help retain lubricant inside the bearing while restricting the ingress of external contaminants into the rolling contact area.

This construction should not be confused with:

6206-2Z/C3

The 2Z version uses non-contact metal shields rather than the contact seals used in the 2RS1 version.

Although the principal dimensions can be identical, the closure design is technically different.

What Does C3 Mean?

The suffix C3 identifies a radial internal clearance range greater than Normal.

Internal clearance is an important bearing selection parameter because the remaining operating clearance can be affected by:

shaft fit, housing fit, temperature differences and operating conditions.

C3 does not mean that the bearing is universally better than a Normal-clearance version.

When the original machine specification requires 6206-2RS1/C3, the C3 clearance designation should be retained unless the operating conditions are reassessed.

Loads and Operating Principle

The deep groove raceway geometry enables SKF 6206-2RS1/C3 to accommodate primarily:

radial loads

and also:

axial loads in both directions

within the operating limits of the bearing.

SKF specifies the following basic load ratings:

Basic dynamic load rating C: 20.3 kN
Basic static load rating C0: 11.2 kN

These values are engineering parameters used for bearing selection and life calculations.

They should not be interpreted as simple maximum permissible machine loads without considering load direction, rotational speed, fits, operating temperature and required bearing life.

Limiting Speed

For SKF 6206-2RS1/C3, the confirmed limiting speed is:

8,000 r/min

This value applies to the specific sealed and grease-lubricated bearing configuration.

The limiting speed should not automatically be treated as the recommended continuous operating speed for every installation.

Actual permissible operating conditions depend on the complete bearing arrangement.

Sheet Metal Cage

SKF specifies a:

sheet metal cage

for this exact bearing reference.

The cage maintains separation and circumferential spacing of the rolling elements during operation.

When comparing a potential replacement, cage construction should be checked if it is relevant to the machine specification or operating conditions.

SKF 6206-2RS1 C3 vs 6206-2RS1

The principal dimensions and sealing arrangement can be identical, but the internal clearance specification differs.

6206-2RS1: version without the C3 suffix.

6206-2RS1/C3: C3 radial internal clearance greater than Normal.

The C3 suffix should therefore not be removed when identifying an existing 6206-2RS1/C3 bearing.

SKF 6206-2RS1 C3 vs 6206-2Z C3

These versions can share the same 30x62x16 mm principal dimensions and C3 clearance, but they use different closure systems.

6206-2RS1/C3: contact seals on both sides.

6206-2Z/C3: non-contact metal shields on both sides.

The two versions should not automatically be considered technically identical solely because their dimensions and internal clearance class match.

Meaning of SKF 6206-2RS1/C3

The complete manufacturer designation provides important information about the bearing:

6206 - basic designation of the deep groove ball bearing

2RS1 - contact seals on both sides

C3 - radial internal clearance greater than Normal

Official manufacturer designation:

SKF 6206-2RS1/C3

For internal search purposes, the same product can also be identified as:

SKF 6206-2RS1 C3

This preserves the technical meaning of the designation while allowing identification without the slash character.

Selection and Interchangeability

When selecting a replacement for SKF 6206-2RS1/C3, compare at least:

Bearing type: Single-row deep groove ball bearing
d: 30 mm
D: 62 mm
B: 16 mm
Closure: Contact seals on both sides
Internal clearance: C3
Dynamic load rating: 20.3 kN for this SKF reference
Static load rating: 11.2 kN for this SKF reference
Cage: Sheet metal
Bore: Cylindrical
Speed capability: Appropriate for the operating conditions

The same 6206 basic designation and identical 30x62x16 mm dimensions do not by themselves establish complete interchangeability.

Other manufacturers can also use different suffix systems to describe seals, shields, internal clearance and other design features.
