⚙ Technical Specifications & Dimensional Parameters
The table below provides complete specifications for the 6008 2RS model so you can confidently replace it in your system.
💎 Engineering Advantages of KGI Brand for This Model
🔒 Complete Enclosure Sealing
Dual NBR (Nitrile Rubber) seal rings on both sides completely block contaminants, moisture, and dust while retaining the internal factory grease.
🌀 Ultra-Low Noise Level
High precision in raceway polishing and ball sizing guarantees ultra-quiet performance for sensitive applications like electric motors and cooling fans.
Self-Lubricated Design
This bearing comes fully pre-greased and sealed from the factory, eliminating the need for periodic re-lubrication in most standard operations.
📖 Comprehensive Practical Guide & Installation Tips
The 6008 bearing, featuring a 40 mm inner diameter, is commonly installed on electric motor shafts, pumps, and workshop machinery, serving as a core component for a wide range of industrial power units.
Key Tips to Extend Service Life:
- Proper Press-Fit Installation: Never use a sledgehammer or direct impacts to drive the bearing onto the shaft. Direct shocks deform the rubber seals (RS), leading to seal failure and particle contamination.
- Operating Temperature Control: Avoid using this standard model in environments exceeding 120°C unless specialized high-temperature grease and seals are specified.
- Do Not Wash Sealed Bearings: Sealed bearings should never be washed with solvents or liquid cleaners, as this flushes out the essential internal grease.
- External Surface Protection: When needed, only the outer metallic surfaces of the bearing rings should be lightly coated with suitable protective grease or anti-rust oil.
The 6000 series is highly popular due to its excellent operating speed range (RPM). This specific model, featuring robust contact seals, prevents grease leakage during operation near electric motor windings.
❓ Frequently Asked Questions
What is the difference between 2RZ and 2RS models?
The 2RS model uses full-contact rubber seals offering maximum protection against dust and moisture ingress. The 2RZ model uses non-contact or light-contact seals, making it better suited for higher speeds and lower friction requirements.
Can this bearing be used in low-temperature environments?
Yes, the nitrile rubber seals and standard synthetic grease in this model are engineered for an operating temperature range of -40°C to +120°C, making it ideal for cold operating conditions.
Is this size suitable for domestic water pumps?
If your pump shaft has a 40 mm diameter, yes. The 2RS rubber seals provide excellent protection against moisture and water splash, making it highly reliable for motor pumps.
