Product Introduction: FAGI 6307 2RS C3 P6
The FAGI 6307 2RS C3 P6 Single Row Deep Groove Ball Bearing is a precision-engineered component designed specifically for applications requiring thermal stability, smooth rotation, and low vibration. Built for 35mm shafts and medium-to-heavy industrial loads (6300 series), this bearing integrates two critical features: P6 high-precision accuracy and C3 increased internal clearance.
The P6 tolerance class (equivalent to ABEC-3 and ISO Class 6) signifies tighter tolerances and higher geometric accuracy than standard bearings (P0). This translates directly into reduced rotational run-out, minimal noise levels, and stable operation at higher speeds. Furthermore, the C3 specification provides the necessary expansion space for rings and balls during continuous operation, preventing seizing, excessive internal stress, and premature failure.
This FAGI industrial bearing comes equipped with 2RS contact rubber seals and is pre-lubricated with high-performance industrial grease, ensuring a Maintenance-Free operation, even in dusty or contaminated environments.
Technical Code Breakdown (6307 2RS C3 P6)
6: International designation for a Single Row Deep Groove Ball Bearing.
3: Dimension Series indicator (Medium Duty Series) featuring robust balls and a thicker outer ring compared to 60 or 62 series.
07: Bore/Shaft size code: 07 × 5 = 35 mm.
2RS: Equipped with two rubberized (NBR) contact seals with a reinforced steel cage on both sides to retain grease and block contaminants.
C3: Internal radial clearance larger than the standard (Normal) grade; prevents seizing due to thermal expansion under load or tight shaft fits.
P6: High dimensional and geometric accuracy based on ISO Class 6 (ABEC-3) for minimal run-out and vibration.
Standard Dimensions and Specifications
| Bore (d) | Outer (D) | Width (B) | Accuracy | Clearance | Sealing | Lubrication |
|---|---|---|---|---|---|---|
| 35 mm | 80 mm | 21 mm | P6 (Class 6) | C3 | 2RS (Rubber) | Factory Lifetime Grease |
Key Advantages and Features
P6 Precision (Reduced Noise & Run-out)
Tighter tolerances and ISO P6 geometric standards drastically reduce micro-vibrations and operational noise.
C3 Clearance for Thermal Shock
C3 clearance compensates for thermal expansion of the shaft and inner ring at high speeds, preventing seizing.
2RS Sealing Protection
Contact seals with a steel frame prevent ingress of dust, moisture, and debris, while ensuring excellent grease retention.
6300 Series Heavy Load Capacity
The robust 80mm outer diameter and high-strength balls provide reliable performance under heavy combined loads.
Hardened Alloy Steel (100Cr6)
Manufactured from high-grade chrome steel subjected to precision heat treatment for superior surface fatigue resistance.
Maintenance-Free
Factory-filled with premium industrial grease, eliminating the need for periodic relubrication.
Common Industrial Applications
Due to its unique blend of precision and thermal endurance, the FAGI 6307 2RS C3 P6 is a top choice for:
- Industrial VFD Electric Motors: Motors requiring C3 clearance and low run-out (P6) due to variable frequency and heat.
- Industrial Pumps & Turbopumps: Ideal for 35mm shafts operating at high speeds with continuous flow, requiring 2RS sealing.
- Industrial Gearboxes: Reducing vibration via P6 tolerance, ensuring durability under heavy radial loads.
- Refrigeration Compressors: Reliable resistance to thermal cycles during start/stop operations.
- Textile Machinery: Smooth, stable, and vibration-free operation in high-volume production lines.
Engineering Selection & Buying Guide
- Importance of C3: If your shaft requires an interference fit or the machine operates at high temperatures, C3 is mandatory. Standard clearance in these conditions can lead to ball binding and premature failure.
- The P6 Advantage: Using P6 accuracy instead of standard P0 extends bearing and shaft life by up to 30% and reduces operating temperature.
- Environmental Compatibility: 2RS rubber seals are the optimal barrier against dust and humidity. For supercritical speeds exceeding seal limits, steel-shielded (ZZ) versions should be considered.
- Brand Authenticity: When purchasing, check for precise laser etching of the code 6307 2RS C3 P6 and the FAGI brand on both the rings and the sealed packaging.
Critical Installation & Mounting Tips
1) Apply Pressure Only to the Shaft-Mounted Ring
When mounting on a 35mm shaft, force must be applied exclusively to the inner ring. Pressure applied through the rolling elements creates micro-dents on the P6 raceway, destroying the precision.
2) Never Use Open Flame for Heating
Open flames degrade the 2RS rubber and destroy the internal grease. If pre-heating is necessary, use a controlled induction heater (max 110°C).
3) Ensure Clean Seat Surfaces
Even a few microns of dirt or burrs on the housing or shaft will negate P6 accuracy. Polish and clean mating surfaces thoroughly.
4) Do Not Remove 2RS Seals
The bearing is factory-filled with the correct amount of high-quality grease; removing the seal to add extra or different grease will deform the lip geometry and cause leakage.
Troubleshooting & Symptoms
- Loud Whining Noise After Installation: Indicates an excessively tight shaft fit (even C3 clearance is insufficient) or impact damage to the raceway during mounting.
- Excessive Bearing Heat: Could be caused by misalignment between the shaft and housing, or operating speeds exceeding the limits of the 2RS contact seals.
- High-Frequency Vibration: Check for dynamic rotor imbalance or damage to the raceway.
Frequently Asked Questions (FAQ)
1) What are the dimensions of this bearing?
This bearing has a 35mm bore (inner diameter), 80mm outer diameter, and 21mm width.
2) Does this bearing need lubrication after installation?
No; the FAGI 6307 2RS is pre-filled with high-grade industrial grease at the factory and is maintenance-free.
Conclusion
The FAGI 6307 2RS C3 P6 deep groove ball bearing is an excellent choice for 35mm shafts operating under sensitive conditions. The combination of P6 rotational accuracy, C3 thermal resilience, and reliable 2RS sealing ensures smooth, long-lasting, and maintenance-free performance for your equipment.
