SKF W 6206-2RS1 30x62x16 Stainless Steel Deep Groove Ball Bearing

SKF W 6206-2RS1 is a single-row stainless steel deep groove ball bearing with dimensions of 30x62x16 mm. It has a 30 mm bore diameter, 62 mm outside diameter and 16 mm width. The W prefix identifies the stainless steel SKF bearing series, while 2RS1 identifies the sealed configuration. SKF catalogue data specify C = 16.5 kN, C0 = 11.2 kN and a limiting speed of 7000 r/min for this exact size and configuration.

SKF W 6206-2RS1 - Product Characteristics

The exact bearing belongs to SKF's stainless steel deep groove ball bearing range.

Verified catalogue parameters are:

Designation: W 6206-2RS1
Bearing type: Single-row deep groove ball bearing
Material series: Stainless steel
Dimensions: 30x62x16 mm
Basic dynamic load rating C: 16.5 kN
Basic static load rating C0: 11.2 kN
Fatigue load limit Pu: 0.48 kN
Limiting speed: 7000 r/min
Mass: approximately 0.196 kg

The stainless steel construction is a fundamental part of this bearing's identification. W 6206-2RS1 should therefore not be treated as the same product as a standard SKF 6206-2RS1, even though both share the principal dimensions 30x62x16 mm.

Dimensions

The principal dimensions of SKF W 6206-2RS1 are:

d - Bore Diameter: 30 mm
D - Outside Diameter: 62 mm
B - Width: 16 mm
Commercial Size: 30x62x16 mm

SKF additionally specifies:

r1,2 - Minimum chamfer dimension: 1 mm
da - Shaft abutment diameter: min. 35 mm, max. 40.5 mm
Da - Maximum housing abutment diameter: 57 mm
ra - Maximum shaft or housing fillet radius: 1 mm.

For this bearing, the commercial dimensional sequence 30x62x16 mm corresponds to d x D x B.

Stainless Steel Construction - W Prefix

The W prefix is essential in the SKF designation.

SKF classifies W 6206-2RS1 under its stainless steel deep groove ball bearing range.

This differentiates the bearing from the standard 6206 series manufactured as conventional bearing-steel variants.

The distinction also affects technical parameters. For example, SKF catalogue data give a dynamic load rating of 16.5 kN for W 6206-2RS1, so load ratings from a conventional SKF 6206 variant should not simply be copied to this stainless steel version.

The W prefix must therefore remain in the product designation during identification, ordering and replacement selection.

Deep Groove Ball Bearing Design

SKF W 6206-2RS1 is a single-row deep groove ball bearing.

The balls operate between deep raceway grooves in the inner and outer rings. This geometry enables the bearing to support radial loads and also accommodate axial loading in both directions.

The bearing has a cylindrical 30 mm bore and belongs to the metric 6200 dimensional series.

Its deep groove construction should not be confused with angular contact, self-aligning or other bearing designs that may have different axial-load characteristics.

2RS1 Sealed Configuration

The designation 2RS1 identifies the sealed version of the bearing. SKF catalogue listings distinguish W 6206-2RS1 from the shielded W 6206-2Z and open W 6206 variants.

The seals help retain lubricant within the bearing and reduce the ingress of contaminants into the rolling contact area.

This construction difference matters when selecting a replacement. An open W 6206 or shielded W 6206-2Z has the same 30x62x16 mm envelope dimensions but a different closure arrangement.

Load Ratings

SKF specifies the following load ratings for W 6206-2RS1:

Basic Dynamic Load Rating C: 16.5 kN
Basic Static Load Rating C0: 11.2 kN
Fatigue Load Limit Pu: 0.48 kN.

These values are particularly important because they differ from some conventional bearing-steel SKF 6206 variants.

The dynamic load rating C should not be interpreted as a simple maximum permissible machine load. Bearing selection requires consideration of load magnitude and direction, required rating life, speed, fits, temperature and actual operating conditions.

Speed

SKF lists a limiting speed of 7000 r/min for the sealed W 6206-2RS1 stainless steel bearing.

This value belongs to the exact stainless steel sealed configuration and is therefore more appropriate for this product page than speed data copied from a conventional 6206 bearing.

Actual permissible operating speed can be influenced by load, temperature, lubrication, fits and surrounding operating conditions.

Meaning of W 6206-2RS1

The complete designation is important:

W - identifies SKF's stainless steel bearing series.

6206 - identifies the deep groove ball bearing dimensional series and size; code 06 corresponds to a 30 mm bore.

2RS1 - identifies the sealed configuration, with seals on both sides.

The complete designation W 6206-2RS1 should therefore be preserved. Removing the W changes the technical identity of the product.

W 6206-2RS1 vs Standard 6206-2RS1

These bearings have the same principal dimensions:

d: 30 mm
D: 62 mm
B: 16 mm

However, they should not be treated as identical products.

W 6206-2RS1 belongs to SKF's stainless steel bearing range and has its own catalogue load ratings. SKF gives C = 16.5 kN for this stainless steel version.

Therefore, replacing a standard 6206-2RS1 with W 6206-2RS1, or vice versa, should be based on the complete technical requirements rather than dimensions alone.

W 6206-2RS1 vs W 6206-2Z

SKF also lists W 6206-2Z in the same stainless steel series.

Both versions measure 30x62x16 mm, but their closure systems differ. SKF catalogue data also show different speed characteristics: W 6206-2RS1 has a limiting speed of 7000 r/min, while W 6206-2Z is listed with reference and limiting speeds of 26,000 and 13,000 r/min respectively.

They should therefore not be considered identical solely because their dimensions match.

Selection and Interchangeability

When selecting a replacement for SKF W 6206-2RS1, compare:

• complete designation including prefix W,
• stainless steel construction,
• deep groove ball bearing type,
• d = 30 mm,
• D = 62 mm,
• B = 16 mm,
• sealed 2RS1 configuration,
• radial internal clearance,
• dynamic load rating C,
• static load rating C0,
• speed requirement,
• operating environment.

A standard 6206 bearing or another manufacturer's 30x62x16 bearing is not automatically a complete technical equivalent.

The W prefix should never be omitted during technical comparison.
