SKF 6207-2RS1 35x72x17 Deep Groove Ball Bearing

SKF 6207-2RS1 - Product Characteristics

SKF 6207-2RS1 belongs to the 62 dimensional series of single-row deep groove ball bearings.

Verified data for this bearing include:

Manufacturer / Brand: SKF
Designation: 6207-2RS1
Bearing Type: Single-row deep groove ball bearing
Dimensions: 35x72x17 mm
Number of Rows: 1
Bore Type: Cylindrical
Sealing: Both sides
Basic Dynamic Load Rating C: 27 kN
Basic Static Load Rating C0: 15.3 kN
Fatigue Load Limit Pu: 0.655 kN
Limiting Speed: 6300 r/min
Mass: approximately 0.30 kg.

The complete 6207-2RS1 designation should be retained because SKF also catalogues other 6207 configurations with the same 35x72x17 mm principal dimensions.

Dimensions

The principal dimensions of SKF 6207-2RS1 are:

d - Bore Diameter: 35 mm
D - Outside Diameter: 72 mm
B - Width: 17 mm
Commercial Size: 35x72x17 mm

For this bearing, the commercial dimension 35x72x17 mm corresponds to d x D x B. SKF's product search confirms these dimensions specifically for 6207-2RS1.

Bearing Construction

SKF 6207-2RS1 is a single-row deep groove ball bearing.

Its rolling elements operate between deep raceway grooves in the inner and outer rings. This geometry is primarily designed to accommodate radial loading while also allowing axial loads to be supported in both directions.

The bearing has a cylindrical bore and a non-separable basic construction. The deep groove geometry makes the complete bearing designation important when comparing it with other bearing types having the same bore diameter.

2RS1 Sealing

The 2RS1 configuration is sealed on both sides. SKF's product data identify 6207-2RS1 as a sealed single-row deep groove ball bearing.

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

SKF also lists other versions of the same basic size, including:

6207 - open bearing
6207-2RS1 - sealed on both sides
6207-2Z - shielded on both sides
6207-2Z/C3 - shielded version with C3 clearance.

These products share the principal 35x72x17 mm dimensions but are not identical configurations.

Load Ratings and Operating Principle

SKF catalogue data for 6207-2RS1 specify:

C - Basic Dynamic Load Rating: 27 kN
C0 - Basic Static Load Rating: 15.3 kN
Pu - Fatigue Load Limit: 0.655 kN.

The bearing's deep groove raceway geometry enables it to accommodate radial loads and axial loads acting in both directions.

These catalogue ratings should not be interpreted as simple maximum permissible machine loads. Correct bearing selection also depends on actual load conditions, required rating life, rotational speed, fits, internal clearance, lubrication, temperature and the operating environment.

Speed Rating

SKF catalogue data specify a limiting speed of 6300 r/min for the sealed 6207 configuration listed as 6207-2RS1.

This is substantially different from the speed data for open or shielded 6207 variants, which is another reason why the exact closure configuration should be retained when identifying a replacement.

Meaning of 6207-2RS1

The designation can be interpreted as follows:

6 - deep groove ball bearing family

62 - dimensional series

07 - bore code corresponding to a 35 mm bore

2RS1 - sealed configuration with seals on both sides

The complete designation 6207-2RS1 is therefore more precise than the commonly used commercial description 6207 2RS.

SKF 6207-2RS1 vs 6207

Both bearings have the same principal dimensions:

d = 35 mm
D = 72 mm
B = 17 mm

The principal difference is the closure arrangement. 6207 is an open bearing, whereas 6207-2RS1 is sealed on both sides. SKF lists these as separate product configurations.

They should therefore not be treated as identical solely because the dimensions match.

SKF 6207-2RS1 vs 6207-2Z

Both versions measure 35x72x17 mm, but the closure systems differ.

6207-2RS1: seals on both sides
6207-2Z: shields on both sides

The type of closure can affect contaminant protection, lubricant retention, friction and permissible speed. Consequently, 2RS1 and 2Z should not automatically be considered technically identical.

SKF 6207-2RS1 vs 6207-2RS1/C3

This distinction is especially important when selecting this product.

SKF separately catalogues 6207-2RS1/C3 with:

Dimensions: 35x72x17 mm
Sealing: seals on both sides
Sealing type: contact
Radial internal clearance: C3
Cage: sheet metal
Lubricant: grease
Bearing material: bearing steel.

Therefore:

6207-2RS1 ≠ 6207-2RS1/C3

The C3 suffix must not be added to a standard 6207-2RS1 product unless it is present in the actual SKF designation.

Selection and Interchangeability

When selecting a replacement for SKF 6207-2RS1, compare:

• complete bearing designation,
• single-row deep groove construction,
• d = 35 mm,
• D = 72 mm,
• B = 17 mm,
• sealing arrangement,
• radial internal clearance,
• dynamic load rating C,
• static load rating C0,
• speed requirement,
• shaft and housing fits,
• lubrication and operating conditions.

A 35x72x17 mm bearing from another manufacturer is not automatically a complete technical equivalent.

Particular attention should be paid to C3. If the original bearing does not have the C3 suffix, it should not automatically be replaced by a C3 version merely because the dimensions and sealing arrangement are the same.

What type of bearing is SKF 6207-2RS1?

It is a single-row deep groove ball bearing.

What does 2RS1 mean on SKF 6207-2RS1?

The designation identifies the sealed configuration with seals on both sides of the bearing.

What is the load rating of SKF 6207-2RS1?

SKF catalogue data specify C = 27 kN, C0 = 15.3 kN and Pu = 0.655 kN.

What is the limiting speed of SKF 6207-2RS1?

SKF catalogue data list a limiting speed of 6300 r/min for 6207-2RS1.

Can SKF 6207-2RS1 carry axial loads?

Yes. Its deep groove raceway geometry allows the bearing to accommodate axial loads in both directions in addition to radial loading.

Is SKF 6207-2RS1 the same as 6207-2RS1/C3?

No. The C3 version has increased radial internal clearance. SKF catalogues 6207-2RS1/C3 separately.

Can another 6207 2RS 35x72x17 bearing replace SKF 6207-2RS1?

Not automatically. Dimensions, bearing type, sealing, internal clearance, load ratings, speed capability and operating requirements should all be compared before confirming interchangeability.
