FAGI 6310 2RS C3 P6 Deep Groove Ball Bearing
Whenever a large electric motor, industrial pump, or conveyor roller starts spinning, the entire weight, pressure, and torque of that rotation rest on a small yet vital component: the ball bearing. If a bearing fails to handle this pressure or overheats, the production line grinds to a halt, leading to costly repairs. Among various rotating parts, the FAGI 6310 2RS C3 P6 Deep Groove Ball Bearing stands out as a titan for 50mm shaft applications.

Product Detail
FAGI Deep Groove Ball Bearing 6310 2RS C3 P6 Unmatched Power, Thermal Management, and Long-Lasting Durability for 50mm Shafts
The beating heart of heavy-duty industrial machinery, high-torque motors, pressure pumps, and industrial manufacturing plants.
Why is the 6310 a Staple in Industrial Engineering?
Whenever a large electric motor, industrial pump, or conveyor roller starts spinning, the entire weight, pressure, and torque of that rotation rest on a small yet vital component: the ball bearing. If a bearing fails to handle this pressure or overheats, the production line grinds to a halt, leading to costly repairs. Among various rotating parts, the FAGI 6310 2RS C3 P6 Deep Groove Ball Bearing stands out as a titan for 50mm shaft applications.
The "10" in the code signifies a 50mm inner diameter, a critical size where loads move from light to medium-heavy duty. When combined with the "63" series designation—which features thicker steel walls and larger balls—this bearing is built to endure relentless, high-temperature industrial environments. With the added protection of 2RS rubber seals and the thermal flexibility of C3 clearance, this bearing is designed for those who demand reliability and want to avoid frequent maintenance.
Decoding the Technical Specs
- 6: Indicates a Deep Groove Ball Bearing. This design excels at handling both vertical (radial) and side-load (axial) forces.
- 3: Specifies the "Heavy" series. It has greater metal thickness and larger balls than the 60 or 62 series, providing superior impact resistance.
- 10: Defines the bore size. For bearing codes above 04, multiply by 5. 10 × 5 = 50mm inner diameter.
- 2RS: Dual-sided rubber seals. These keep high-quality lubricant inside and block dust, debris, and moisture from the outside.
- C3: Higher internal clearance. This allows the bearing to expand safely during high-heat operation, preventing seizure.
- P6: Superior manufacturing precision. Tighter tolerances result in minimal vibration, lower noise, and smoother rotation.
Geometric Dimensions
- Inner Diameter (Bore): 50 mm
- Outer Diameter: 110 mm
- Width (Thickness): 27 mm
Note: Do not confuse 6310 with 6210. While both fit a 50mm shaft, 6310 is much more robust with an 110mm outer diameter, whereas 6210 is only 90mm.
Key Advantages
High Load Capacity
The robust 63 series design withstands sudden shocks and heavy weights that would crush lighter bearings.
Zero-Maintenance
2RS seals ensure the pre-applied factory lubricant stays in place, eliminating the need for constant re-greasing.
Thermal Stability
C3 clearance allows for thermal expansion, ensuring the bearing runs cool and smooth in high-temperature cycles.
Precision Performance
P6 precision reduces vibration and operational noise, extending the lifespan of connected equipment.
Best Practices for Installation
1. Absolute Cleanliness
Clean the shaft and housing thoroughly. Even tiny metal shavings can damage the race and cause premature failure.
2. Apply Force Correctly
When fitting on a shaft, press the inner ring. When inserting into a housing, press the outer ring. Never press on the seals or balls.
3. Avoid Direct Hammering
Direct steel hammer blows cause micro-cracks in the hardened steel. Use a hydraulic press or proper fitting sleeves.
4. Heat Carefully
If thermal mounting is needed, use an induction heater. Never use an open flame, as it will ruin the rubber seals and grease.
Frequently Asked Questions (FAQ)
1) Can I replace 6310 with 6210?
No. 6310 is physically larger (110mm outer vs 90mm) and designed for heavier loads. They are not interchangeable in the same housing.
2) Is 2RS better than ZZ (metal shield)?
2RS offers superior protection against dust and moisture. While ZZ is good for very high speeds, 2RS is the ideal all-rounder for most industrial applications.
3) Why choose C3 clearance?
C3 clearance is essential for electric motors and high-heat applications to account for metal expansion during operation.
4) Do I need to grease before installing?
No. FAGI 2RS bearings are pre-lubricated with high-grade grease at the factory for their entire service life.
