6205-2RS C3 Deep Groove Ball Bearing

The 6205-2RS C3 deep groove ball bearing combines two rubber contact seals with C3 internal clearance. This configuration is designed for applications where additional internal clearance is required to accommodate operating temperature, thermal expansion or specific operating conditions.

The 6205-2RS C3 is based on the widely used 6205 single-row deep groove ball bearing design. It has the same basic boundary dimensions as other 6205 variants, while the C3 clearance and 2RS sealing configuration provide different operating characteristics.

Key Features of 6205-2RS C3

• C3 internal clearance: The C3 specification provides greater radial internal clearance than Normal clearance and can be useful in applications involving heat and thermal expansion.
• Double rubber seals: 2RS seals help retain lubricant and protect the internal bearing components from dust, dirt and moisture.
• Standard 6205 dimensions: The basic dimensions remain 25 mm bore, 52 mm outside diameter and 15 mm width.
• Suitable for rotating equipment: The bearing is commonly considered for electric motors and other machinery where temperature and clearance must be taken into account.
• Reduced maintenance requirements: The sealed construction helps retain factory-applied grease and reduces the need for external lubrication.
• Easy sourcing: The internationally recognized 6205 designation makes cross-reference and replacement sourcing straightforward.

What Does C3 Mean on a Bearing?

C3 indicates an internal radial clearance greater than the Normal clearance range. Internal clearance is the amount of relative movement between the rolling elements and raceways before the bearing is installed or operating under load.

When a bearing operates at elevated temperature, the inner ring can expand relative to the outer ring. In suitable applications, additional internal clearance can help compensate for this thermal expansion and prevent excessive reduction of operating clearance.

The correct clearance should always be selected according to the equipment design, shaft and housing fits, operating temperature, speed and load. C3 should not automatically be considered better than Normal clearance for every application.

6205-2RS C3 Applications

6205-2RS C3 is commonly considered for rotating equipment where both sealing and increased internal clearance are required. Typical applications include:

• Electric motors
• Industrial motors
• Pumps
• Fans and blowers
• Conveyors
• Agricultural machinery
• Industrial machinery
• Gearboxes
• General rotating equipment

6205-2RS C3 Bearing Replacement

When selecting a replacement bearing, it is important to match the complete bearing designation. A standard 6205, 6205-2RS, 6205-ZZ and 6205-2RS C3 may share the same basic boundary dimensions, but their sealing and internal clearance configurations are different.

For applications involving electric motors, elevated operating temperatures or specific shaft and housing fits, the C3 clearance should be confirmed before replacing a Normal-clearance bearing.

FAQ About 6205-2RS C3

What is a 6205-2RS C3 bearing?

6205-2RS C3 is a single-row deep groove ball bearing with double rubber seals and C3 internal clearance. It combines contamination protection with greater-than-normal radial internal clearance.

What are the dimensions of 6205-2RS C3?

The standard boundary dimensions are 25 mm bore, 52 mm outside diameter and 15 mm width.

What does C3 mean?

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

Is 6205-2RS C3 suitable for electric motors?

6205-2RS C3 is commonly used in motor-related applications, particularly where operating temperature and thermal expansion make increased internal clearance appropriate. The final selection should be based on the motor design and operating conditions.

What is the difference between 6205-2RS C3 and 6205-ZZ?

6205-2RS C3 uses double rubber seals and C3 internal clearance, while 6205-ZZ uses double metal shields and normally has standard internal clearance unless otherwise specified.
