SKF 6206-2RS1 30x62x16 Deep Groove Ball Bearing

SKF 6206-2RS1 - Product Characteristics

The exact SKF product specification identifies 6206-2RS1 as a metric, single-row deep groove ball bearing.

Verified characteristics include:

Bearing type: Deep groove ball bearing
Number of rows: 1
Bore type: Cylindrical
Sealing: Seal on both sides
Sealing type: Contact
Radial internal clearance: CN
Cage design: Sheet metal
Lubricant: Grease
Bearing material: Bearing steel
Coating: None
Net weight: approximately 0.20 kg

These parameters are important because a bearing identified only as “6206 2RS” does not communicate the complete SKF specification as precisely as 6206-2RS1.

Dimensions

The principal dimensions of SKF 6206-2RS1 are:

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

For this bearing, the dimensional notation 30x62x16 mm corresponds directly to d x D x B. SKF's current product page confirms all three dimensions for the exact 6206-2RS1 variant.

Deep Groove Ball Bearing Construction

SKF 6206-2RS1 is a single-row deep groove ball bearing. Its balls run between deep raceway grooves in the inner and outer rings.

This geometry is designed primarily for radial loading but can also accommodate axial loads acting in both directions. This distinguishes the construction from bearing types designed to support axial load predominantly or exclusively in one direction.

The bearing has a cylindrical 30 mm bore and a sheet-metal cage. SKF specifies bearing steel as the bearing material for this exact product.

2RS1 Sealing

The 2RS1 suffix is technically important because this exact SKF version is equipped with contact seals on both sides.

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

The sealed construction also differentiates 6206-2RS1 from other SKF 6206 configurations such as open 6206 and shielded 6206-2Z. These products share the same principal 30x62x16 mm dimensions but should not automatically be treated as identical variants. SKF lists these configurations separately.

Internal Clearance, Cage and Lubrication

For the exact SKF 6206-2RS1 product, SKF specifies:

Radial Internal Clearance: CN
Cage: Sheet metal
Lubrication: Grease

CN identifies the normal radial internal clearance group for this version.

This is particularly relevant when comparing the bearing with a 6206-2RS1/C3 or another variant carrying an additional clearance suffix. A C3 bearing has a different internal-clearance specification and should not automatically be substituted for a CN bearing simply because the principal dimensions are identical.

Load Ratings and Operating Principle

For the standard SKF 6206 bearing size, SKF catalogue data give:

Basic Dynamic Load Rating C: 20.3 kN
Basic Static Load Rating C0: 11.2 kN
Fatigue Load Limit Pu: 0.475 kN

SKF catalogue data for the sealed 6206-2RSH configuration also show a 7,500 r/min limiting speed.

However, because the exact current product page retrieved for 6206-2RS1 does not expose a speed value, I would not automatically assign the 2RSH speed specification to 6206-2RS1 on the product page.

The values C and C0 are bearing load ratings, not simple maximum permissible operating loads. Actual bearing selection requires consideration of load direction and magnitude, speed, required service life, shaft and housing fits, temperature and operating conditions.

Meaning of SKF 6206-2RS1

The designation identifies the bearing more precisely than the generic phrase “6206 2RS”.

6206 identifies the basic deep groove ball bearing size and dimensional series.

06 corresponds to a nominal bore diameter of 30 mm.

2RS1 identifies the SKF sealed configuration, with the exact product data confirming contact seals on both sides.

The complete designation should therefore be retained when identifying or ordering the bearing.

SKF 6206-2RS1 vs 6206-2Z

SKF lists both 6206-2RS1 and 6206-2Z with principal dimensions of 30x62x16 mm.

They are not the same execution.

6206-2RS1 uses contact seals on both sides.

6206-2Z uses shields rather than the 2RS1 contact-seal configuration.

Consequently, matching d, D and B does not by itself establish that two 6206 variants are operationally interchangeable.

Selection and Interchangeability

When selecting a replacement for SKF 6206-2RS1, compare more than the 30x62x16 mm dimensions.

The critical parameters include the bearing type, 30 mm bore, 62 mm outside diameter, 16 mm width, sealing arrangement, internal clearance, cage design, load ratings, speed requirements and operating conditions.

Particular attention should be paid to additional suffixes. For example, 6206-2RS1/C3 should not automatically be treated as identical to 6206-2RS1, because the internal-clearance specification differs.

Likewise, a 6206 bearing from another manufacturer is not proven to be a complete technical equivalent solely because it has the same dimensions.

FAQ

What are the dimensions of SKF 6206-2RS1?

SKF 6206-2RS1 measures 30x62x16 mm: 30 mm bore diameter, 62 mm outside diameter and 16 mm width.

What type of bearing is SKF 6206-2RS1?

It is a single-row deep groove ball bearing with a cylindrical bore and seals on both sides.

What does 2RS1 mean on SKF 6206-2RS1?

For this exact SKF product, 2RS1 identifies the version with contact seals on both sides.

What internal clearance does SKF 6206-2RS1 have?

SKF specifies CN normal radial internal clearance for the exact standard 6206-2RS1 product.

What cage does SKF 6206-2RS1 use?

SKF specifies a sheet-metal cage for this exact variant.

What loads can SKF 6206 accommodate?

The deep groove ball bearing design accommodates primarily radial loads and can also support axial loading in both directions. SKF catalogue ratings for the standard 6206 size are C = 20.3 kN and C0 = 11.2 kN.

Is SKF 6206-2Z the same as 6206-2RS1?

No. Both have 30x62x16 mm principal dimensions, but the sealing arrangements differ. SKF lists them as separate product variants.

Can 6206-2RS1/C3 replace 6206-2RS1?

Not automatically. The additional C3 suffix identifies a different radial internal clearance group, so the required clearance must be checked for the specific bearing arrangement.
