SKF 6306-2RS1/C3 – Technical Characteristics

SKF 6306 Bearing Dimensions – 30x72x19 mm

The principal dimensions of SKF 6306-2RS1/C3 are:

d = 30 mm – bore diameter

D = 72 mm – outside diameter

B = 19 mm – bearing width

Complete dimensional designation:

30x72x19 mm

Users searching primarily by dimensions may enter:

30x72x19 bearing

SKF 30x72x19 bearing

6306 bearing 30x72x19

30x72x19 C3 bearing

30x72x19 sealed bearing

30mm bore 72mm OD bearing

Dimensions alone do not fully identify the bearing. The sealing configuration and C3 internal clearance must also be verified.

Single Row Deep Groove Ball Bearing

SKF 6306-2RS1/C3 is a single row deep groove ball bearing.

The bearing consists principally of an inner ring, outer ring, one row of balls and a cage that separates and guides the rolling elements.

Deep groove ball bearings are primarily designed to accommodate radial loads, while their raceway geometry also allows them to carry axial loads in both directions.

The actual permissible load and operating conditions depend on the complete bearing arrangement, speed, fits, temperature and other application parameters.

What Does 6306 Mean?

6306 is the basic bearing designation.

The bore code:

06

corresponds to a nominal bore diameter of:

30 mm.

The principal dimensions are:

30x72x19 mm.

The basic 6306 designation alone does not identify the sealing arrangement or radial internal clearance.

For this product, the complete designation is:

SKF 6306-2RS1/C3.

What Does 2RS1 Mean on an SKF Bearing?

2RS1 identifies a bearing sealed on both sides.

The seals help protect the rolling-contact area from contaminants and help retain lubricant within the bearing.

Therefore, variants such as:

6306

6306-2Z

6306-2RS1

and:

6306-2RS1/C3

should not automatically be treated as identical simply because their principal dimensions are the same.

SKF 6306 2RS C3 vs SKF 6306-2RS1/C3

Many buyers search for this bearing as:

SKF 6306 2RS C3

or:

6306 2RS C3 SKF.

These are useful and common simplified search formats for a 6306 bearing sealed on both sides with C3 clearance.

For technical identification, the exact designation of the product described here is:

SKF 6306-2RS1/C3.

Therefore:

6306-2RS1/C3 = exact product identification

while:

6306 2RS C3 = commonly used search terminology.

The complete manufacturer designation should be verified before ordering.

What Does C3 Mean?

C3 specifies radial internal clearance greater than the Normal clearance group.

C3 is not a quality grade and does not mean that the bearing is automatically more precise or stronger.

It identifies a specific internal-clearance group and is therefore an important part of the bearing designation.

Why Is C3 Clearance Important?

A bearing's internal clearance can change after installation and during operation.

Factors influencing operating clearance include:

shaft fit

housing fit

interference mounting

inner-ring temperature

outer-ring temperature

and:

operating conditions.

For this reason, an SKF 6306 bearing without C3 should not automatically be substituted for 6306-2RS1/C3 solely because the dimensions match.

Basic Dynamic Load Rating Cr – 29.6 kN

The basic dynamic load rating is:

Cr = 29.6 kN.

Cr is a standardized bearing parameter used when calculating bearing rating life under dynamic loading.

It should not be interpreted simply as the maximum load that may be applied under all operating conditions.

Basic Static Load Rating C0 – 16 kN

The basic static load rating is:

C0 = 16 kN.

This parameter is used when evaluating bearings under static loading, very slow movement or comparable operating conditions.

SKF 6306-2RS1/C3 Limiting Speed

The specified limiting speed is:

6300 rpm.

The actual acceptable operating speed in a machine also depends on factors such as load, temperature, fits, lubrication and the surrounding bearing arrangement.

SKF 6306-2RS1/C3 vs 6306-2RS1

The important difference is:

C3 radial internal clearance.

The 6306-2RS1/C3 version has radial internal clearance greater than Normal.

Therefore, a 6306-2RS1 bearing without the C3 suffix should not automatically be considered equivalent.

SKF 6306-2RS1/C3 vs 6306-2Z/C3

Both variants can share the principal dimensions:

30x72x19 mm

and the:

C3 clearance group.

However, the closure configuration differs.

2RS1 – sealed on both sides.

2Z – shielded on both sides.

The correct version should be selected according to the original bearing position and operating requirements.

Selection and Interchangeability

When selecting an alternative for SKF 6306-2RS1/C3, verify:

bearing type – single row deep groove ball bearing

bore diameter – 30 mm

outside diameter – 72 mm

width – 19 mm

cylindrical bore

double-sided sealing

C3 radial internal clearance

required load ratings

required operating speed

and:

mounting and operating conditions.

Matching only the 30x72x19 mm dimensions does not confirm full interchangeability.

6306 2RS C3 SKF – Is This the Same Bearing?

The search phrase:

6306 2RS C3 SKF

is commonly used for an SKF 6306 bearing sealed on both sides and manufactured with C3 internal clearance.

For the product described here, the exact SKF designation is:

6306-2RS1/C3.

Therefore, 6306 2RS C3 is useful search terminology, while the full SKF designation should be used for technical verification and ordering.

SKF 6306 C3 Bearing – Is This Search Specific Enough?

A search for:

SKF 6306 C3

identifies the manufacturer, basic bearing size and C3 internal-clearance group.

It does not, however, fully specify the closure configuration.

For this product, the complete configuration includes:

6306 + 2RS1 + C3.

The full product designation is therefore:

SKF 6306-2RS1/C3.

30x72x19 Bearing – How to Identify the Correct Version

Buyers who know only the dimensions may search for:

30x72x19 bearing

30x72x19 C3 bearing

30x72x19 sealed bearing

or:

30x72x19 2RS C3 bearing.

These dimensions identify the basic bearing size but not its complete construction.
