SKF 6202-2Z 15x35x11 Deep Groove Ball Bearing

SKF 6202-2Z, commonly searched and sold as SKF 6202 ZZ, is a single-row deep groove ball bearing measuring 15x35x11 mm. Its bore diameter d is 15 mm, outside diameter D is 35 mm and width B is 11 mm. The 2Z configuration has non-contact metal shields on both sides, while the standard bearing has Normal CN radial internal clearance.

SKF 6202-2Z - Product Characteristics

SKF 6202-2Z belongs to the 62 dimensional series of single-row deep groove ball bearings. Its deep raceway geometry enables the bearing to accommodate primarily radial loads while also carrying axial loads in both directions.

The exact 6202-2Z configuration combines a cylindrical bore, two non-contact metal shields, Normal radial internal clearance and grease lubrication. The shields help retain lubricant within the bearing and restrict the ingress of contaminants without operating as rubbing contact seals.

Dimensions

The principal dimensions of SKF 6202-2Z are:

d - Bore Diameter: 15 mm
D - Outside Diameter: 35 mm
B - Width: 11 mm
Dimensions: 15x35x11 mm.

For this bearing, the dimensional notation 15x35x11 mm corresponds to d x D x B.

Although these dimensions identify the 6202 envelope, dimensions alone do not define the complete bearing. Closure type, radial internal clearance and other construction parameters must also be checked when selecting a replacement.

Bearing Construction

SKF 6202-2Z is a non-separable, single-row deep groove ball bearing.

The rolling elements operate between deep raceway grooves in the inner and outer rings. This construction enables the bearing to accommodate radial loads together with axial loads acting in both directions.

The product should therefore be distinguished from other bearing types that may share a 15 mm bore but have different raceway geometry or load-carrying characteristics.

2Z Non-Contact Metal Shields

The suffix 2Z is a key part of the exact product identification.

SKF specifies the 6202-2Z as:

Sealing: shield on both sides
Sealing type: non-contact.

The metal shields are positioned on both sides of the bearing. Their non-contact construction differs fundamentally from rubbing elastomer seals.

This configuration helps retain the factory grease while restricting contamination ingress, with lower seal friction than a contact-sealed configuration.

The commonly used commercial notation ZZ refers to the same general double-shield concept, but SKF's exact designation should be retained as:

6202-2Z

CN Radial Internal Clearance

The standard SKF 6202-2Z has Normal radial internal clearance, identified as CN in SKF product data.

This is important because SKF also lists:

6202-2Z/C3

as a separate product configuration.

C3 specifies radial internal clearance greater than Normal. Consequently, the two references should not be treated as identical:

SKF 6202-2Z: CN / Normal clearance
SKF 6202-2Z/C3: C3 / greater-than-Normal clearance

The clearance class should therefore be verified when selecting a replacement for a specific bearing arrangement.

Load Ratings and Operating Principle

SKF catalogue data for the 6202 bearing size and 2Z configuration specify:

C - Basic Dynamic Load Rating: 8.06 kN
C0 - Basic Static Load Rating: 3.75 kN
Pu - Fatigue Load Limit: 0.16 kN.

The deep groove raceway geometry enables radial load transmission while also allowing axial loading in either direction.

C, C0 and Pu are engineering parameters used in bearing calculations. They should not be interpreted as simple universal maximum loads that can be applied in every installation.

Speed Ratings

SKF catalogue data specify for 6202-2Z:

Reference Speed: 43,000 r/min
Limiting Speed: 22,000 r/min.

These are distinct engineering parameters.

Actual permissible operating speed depends on the bearing arrangement and operating conditions, including load, temperature, fits, lubrication and heat dissipation.

The speed ratings of a contact-sealed 6202-2RSH should not be transferred to this 2Z version. SKF catalogue data, for example, list a substantially lower limiting speed for the contact-sealed configuration.

Meaning of 6202-2Z

The complete designation identifies the bearing configuration:

6 - deep groove ball bearing

62 - dimensional series

02 - bore code corresponding to 15 mm

2Z - non-contact metal shields on both sides

The technically correct SKF product designation is therefore:

SKF 6202-2Z

The phrase SKF 6202 ZZ can be used naturally as a common commercial designation and search phrase, but it should not replace SKF's manufacturer designation in the technical specification.

SKF 6202-2Z vs 6202-2Z/C3

SKF lists both configurations with dimensions 15x35x11 mm.

The critical difference is internal clearance:

6202-2Z: CN / Normal radial internal clearance

6202-2Z/C3: C3 radial internal clearance greater than Normal

For a product catalogue, these should therefore remain separate technical variants and separate product pages.

SKF 6202-2Z vs 6202-2RSH

Both variants have the same principal dimensions of 15x35x11 mm, but their closure systems differ.

SKF 6202-2Z: non-contact metal shields on both sides

SKF 6202-2RSH: contact seals on both sides

SKF catalogue data also show different speed characteristics. The 6202-2Z has a limiting speed of 22,000 r/min, compared with 13,000 r/min for the contact-sealed 6202-2RSH.

Identical dimensions therefore do not make these variants technically identical.

Selection and Interchangeability

When selecting an alternative to SKF 6202-2Z, the complete technical configuration should be compared rather than dimensions alone.

Key parameters include:

• single-row deep groove ball bearing construction,
• d = 15 mm,
• D = 35 mm,
• B = 11 mm,
• non-contact metal shields on both sides,
• Normal CN radial internal clearance,
• dynamic and static load ratings,
• speed capability,
• lubrication conditions,
• shaft and housing fits.

A bearing described only as 6202 ZZ 15x35x11 from another manufacturer may share the same envelope dimensions and general closure concept, but this alone does not confirm complete technical equivalence.
