SKF 6202-2Z/C3 Dimensions

Principal dimensions:

d = 15 mm

D = 35 mm

B = 11 mm

Complete size:

15x35x11 mm

These boundary dimensions identify the 6202 bearing size, but they do not identify the complete bearing variant. The 2Z and C3 suffixes are essential parts of the specification.

What Does 2Z Mean?

In SKF nomenclature:

2Z

identifies a bearing with a metal shield on both sides.

For the exact SKF 6202-2Z/C3, the shields are specified as:

non-contact

This design should be distinguished from SKF sealed variants using elastomer sealing elements.

The correct SKF designation is:

6202-2Z/C3

The notation:

6202 ZZ C3

is commonly used in trade and product searches, but is not the primary SKF catalogue designation.

What Does C3 Mean?

The suffix:

C3

identifies radial internal clearance greater than Normal.

This is a technically important distinction between:

SKF 6202-2Z - Normal radial internal clearance

and:

SKF 6202-2Z/C3 - C3 radial internal clearance.

The two bearings share the same basic 15x35x11 mm dimensions but should not be treated as identical variants.

Load Ratings

SKF specifies for 6202-2Z/C3:

C = 8.06 kN - basic dynamic load rating

C0 = 3.75 kN - basic static load rating

These catalogue ratings are used in bearing selection and life calculations. They are not universal maximum machine-load values.

Speed Ratings

SKF specifies:

Reference speed = 43,000 rpm

Limiting speed = 22,000 rpm

Reference speed and limiting speed are different technical parameters and should not be used interchangeably.

Actual permissible operating speed depends on the complete bearing arrangement and operating conditions.

6202-2Z/C3 vs 6202-2Z

The principal difference is radial internal clearance:

6202-2Z/C3 → C3 clearance

6202-2Z → Normal clearance

Both variants have:

15x35x11 mm dimensions

and:

metal shields on both sides

but the internal clearance specification is different.

Therefore, C3 should not be omitted when identifying or ordering this exact bearing.

6202-2Z/C3 vs Sealed 6202 Bearings

The 2Z suffix identifies non-contact metal shields.

A sealed 6202 variant can use elastomer sealing elements instead.

Although the basic bearing dimensions may remain 15x35x11 mm, the closure design can influence friction, contamination protection and operating characteristics.

For replacement selection, the closure type must therefore be checked rather than relying only on the 6202 basic designation.

Selection and Interchangeability

When selecting an equivalent for SKF 6202-2Z/C3, verify:

d = 15 mm

D = 35 mm

B = 11 mm

single-row deep groove ball bearing design

metal shields on both sides

non-contact shield configuration

C3 radial internal clearance

required load ratings

required operating speed

shaft and housing fits

A bearing marked only 6202 should not automatically be considered technically equivalent to 6202-2Z/C3.

FAQ

What are the dimensions of SKF 6202-2Z/C3?

The dimensions are 15x35x11 mm: d = 15 mm, D = 35 mm and B = 11 mm.

Are SKF 6202 ZZ C3 and 6202-2Z/C3 the same designation?

6202 ZZ C3 is commonly used as a commercial/search description. The official SKF designation is 6202-2Z/C3.

What does 2Z mean?

2Z identifies non-contact metal shields on both sides of the bearing.

What does C3 mean?

C3 means that the bearing has radial internal clearance greater than Normal.

What are the load ratings of SKF 6202-2Z/C3?

SKF specifies C = 8.06 kN dynamic load rating and C0 = 3.75 kN static load rating.

What is the limiting speed?

The SKF limiting speed is 22,000 rpm. The reference speed is 43,000 rpm.

Is 6202-2Z the same as 6202-2Z/C3?

No. Their dimensions and shield configuration are the same, but 6202-2Z/C3 has C3 internal clearance, while the standard 6202-2Z has Normal clearance.

Can any 15x35x11 bearing replace SKF 6202-2Z/C3?

No. In addition to dimensions, verify the bearing type, 2Z shield configuration, C3 clearance, load ratings, speed requirements and operating conditions.
