SKF 6006 2RS C3 Ball Bearing (30x55x13 mm)

Benefits & Key Features

• Dual rubber seals (2RS): Provides robust protection against dust, debris, and moisture ingress, retaining the lubricant inside the bearing.

• Increased internal clearance (C3): Allows for thermal expansion and slight misalignment, especially in high-speed or high-temperature environments.

• Low friction and smooth operation: Deep groove geometry ensures low rotational resistance and quiet performance.

• Moderate axial and radial load handling: Designed primarily for radial loads, but capable of limited axial load support.

• Reduced maintenance: Sealed design means the bearing is factory-lubricated and often does not require relubrication in typical use.

• Trusted brand consistency: SKF’s reputation ensures match to industry standards and broad compatibility with other components.

Typical Applications

• Electric motors and drives

• Pumps, fans, blowers

• Gearboxes, transmission systems

• Industrial machinery, automation

• Home appliances, tools

• Conveyor systems, mechanical assemblies

Installation & Maintenance Advice

• Apply installation force only to bearing rings—not through seals.

• Use proper pressing or heating tools to avoid damaging seals.

• The bearing ships pre-lubricated; no relubrication is typically needed unless in extreme conditions.

• Monitor temperature and vibration during early operation for early fault detection.

• In extremely dusty or wet environments, consider alternatives with more robust sealing; however, 2RS often suffices in many industrial contexts.

FAQ - Frequently Asked Questions

Q: What does “6006 2RS C3” mean?
A: “6006” designates the size series (30x55x13 mm), “2RS” indicates dual rubber seals (both sides), and “C3” refers to higher-than-normal internal clearance.

Q: Why use C3 clearance instead of standard?
A: C3 allows for thermal expansion, reduces the risk of seizure at elevated temperatures and compensates for slight misalignment.

Q: How does 6006 2RS C3 compare to 6006 ZZ or standard 6006?
A: 6006 ZZ uses metal shields (less sealing) and standard internal clearance; 6006 2RS C3 offers better sealing and more radial clearance, although with slightly more seal friction.

Q: What is the maximum speed of this bearing?
A: The sealed 6006 2RS C3 is rated up to ~ 8,000 rpm (limiting) under typical conditions.

Q: Does it need relubrication?
A: In standard operating environments, no — the bearing is pre-lubricated and sealed for life. In special or long-duration conditions, periodic lubrication may be considered.
