SKF 607 2RS C3 Deep Groove Ball Bearing 7x19x6 mm

What Is the SKF 607 2RS C3 Ball Bearing?

The SKF 607 2RS C3 is a single-row deep groove ball bearing with dimensions of 7x19x6 mm. It features contact rubber seals on both sides (2RS/2RSH), C3 radial internal clearance and is supplied factory lubricated. The bearing is designed primarily for radial loads while also accommodating axial loads in both directions. The increased C3 clearance makes it suitable for applications where operating temperatures, high rotational speeds or interference fits may reduce the internal clearance during operation.

Construction

The bearing consists of:

• Inner ring
• Outer ring
• Single row of precision steel balls
• Ball cage
• Two contact rubber seals
• Factory-filled grease

The contact seals retain lubricant inside the bearing while protecting the raceways and rolling elements from contamination.

How Does It Work?

The balls roll between precision raceways, minimizing friction while ensuring smooth rotation.

The 2RS seals:

• Retain grease inside the bearing
• Prevent dust ingress
• Protect against moisture
• Reduce contamination
• Extend bearing service life

The C3 internal clearance provides additional radial clearance before operation. During running conditions, thermal expansion or tight shaft and housing fits reduce this clearance toward its optimal operating value.

Why Choose C3 Internal Clearance?

Compared with a standard clearance bearing, C3 offers:

• Increased radial internal clearance
• Better performance at elevated operating temperatures
• Improved suitability for high rotational speeds
• Compensation for interference fits
• Reduced risk of preload caused by thermal expansion

C3 clearance should only be selected when required by the application or equipment manufacturer.

Typical Applications

The SKF 607 2RS C3 is commonly used in:

• Electric motors
• High-speed miniature drives
• Cooling fans
• Small pumps
• Industrial automation
• Precision mechanisms
• Power tools
• Laboratory equipment
• OEM machinery
• Industrial MRO maintenance

Its compact size makes it suitable where installation space is limited and reliable sealed operation is required.

Bearing Selection

Before selecting this bearing, verify:

• Shaft diameter: 7 mm
• Housing bore: 19 mm
• Bearing width: 6 mm

Frequently Asked Questions (FAQ)

What does 2RS mean?

It indicates two contact rubber seals, one fitted on each side of the bearing.

What does C3 mean?

C3 indicates greater radial internal clearance than Normal, allowing proper operating clearance after thermal expansion or interference fits.

Is the bearing pre-lubricated?

Yes. The bearing is supplied factory greased and is ready for installation.

Does the SKF 607 2RS C3 support axial loads?

Yes. Like other deep groove ball bearings, it supports radial loads together with moderate axial loads in both directions.

Does the bearing require relubrication?

Under normal operating conditions, the factory grease is intended for the bearing's service life.

Where is the C3 version typically used?

It is commonly selected for electric motors, high-speed equipment and applications where operating temperature or interference fits reduce the bearing's internal clearance.
