Product Detail
Deep Groove Ball Bearing 6212 2RS C3 P6 by FAGI Smooth Operation, Protective Rubber Seals, Thermal Clearance & P6 Precision
A reliable and powerful choice for heavy electric motors, industrial pumps, gearboxes, and 60mm shafts requiring durability and quiet performance.
Introduction to FAGI 6212 2RS C3 P6 Ball Bearing
In any machinery where a metal shaft rotates, a bearing is a vital component. Its main job is to support the shaft, handle the load, and allow the machine to rotate smoothly without unnecessary vibration or friction. Using a standard, high-quality bearing ensures the machine operates efficiently and quietly. Poor-quality bearings, however, can fail prematurely, leading to potential motor damage or shaft misalignment.
The FAGI 6212 2RS C3 P6 Deep Groove Ball Bearing is a robust and widely used solution for 60mm shaft applications. It consists of two polished steel rings with high-precision steel balls rolling inside. Due to its deep-groove design, it can effectively manage both radial and moderate axial loads.
This specific model offers a comprehensive set of features: dual rubber seals (2RS) to protect against dust and moisture, internal C3 clearance to accommodate thermal expansion, and P6 precision engineering for reduced noise and vibration. FAGI brand products are known for consistent manufacturing quality, making them a reliable choice for various industrial workshops and production lines.
Understanding the Technical Code (6212 2RS C3 P6)
Bearing part numbers follow a global standard. Here is a simple breakdown of what these codes mean:
- 6: Indicates a "Single-Row Deep Groove Ball Bearing," the most versatile and common type of bearing globally.
- 2: Represents the series (width and thickness). The "2" series indicates a standard, sturdy build for general industrial loads.
- 12: Indicates the inner bore diameter (where the shaft goes). In global standards, multiply this by 5 to get the size in mm (12 × 5 = 60). Therefore, the inner diameter is 60 mm.
- Geometric Dimensions: Inner Diameter: 60 mm, Outer Diameter: 110 mm, Width: 22 mm (60x110x22).
- 2RS Suffix: Means there are two flexible rubber seals on both sides. These prevent dirt, metal shavings, and moisture from entering and keep the internal grease inside.
- C3 Suffix: Indicates "Greater-than-normal internal clearance." This provides a microscopic gap to prevent the bearing from seizing or binding when the shaft heats up during long operating hours.
- P6 Suffix: Signifies a higher precision class than standard bearings. This ensures the rings and balls are manufactured to tighter tolerances for smoother, more stable rotation.
Key Advantages of FAGI 6212 2RS C3 P6
Quiet & Smooth Operation
With P6 precision, the internal raceways are polished to minimize friction, resulting in quieter operation in your workspace.
Reliable 2RS Sealing
The reinforced rubber seals effectively block dust, debris, and moisture, protecting the internal components from contamination.
Thermal Resistance (C3)
C3 clearance prevents the bearing from binding or overheating in equipment that generates heat during operation.
High Precision Stability
The P6 grade reduces shaft wobble, minimizing stress on motor mounts and surrounding connections.
Maintenance-Free
Pre-lubricated with high-quality grease at the factory, this bearing requires no daily maintenance or re-greasing.
Robust Build
With a 110mm outer diameter and 22mm width, it is engineered to handle heavy radial loads with stability.
Common Applications
- Industrial Electric Motors: Large dynamos, crushers, and industrial grinders.
- Heavy-Duty Pumps: Main water supply stations, large volute pumps, and high-pressure booster pumps.
- Large Fans & Exhaust Systems: Blowers in steel or cement plants and industrial shed ventilation.
- General Machinery: Shaft systems with a 60mm diameter requiring high-standard reliability.
Buying & Selection Guide
- Measure First: Always use calipers to confirm your shaft measures 60mm, the outer housing 110mm, and the width 22mm.
- Choose the Right Seal: 2RS (Rubber) is ideal for environments with dust or moisture. ZZ (Metal) shields are better for high-temperature applications without moisture.
- Check for C3 Requirement: If your equipment generates significant heat, C3 clearance is essential to prevent binding.
- Precision (P6): Choose P6 if your machine operates at high speeds or requires minimal vibration for accuracy.
- Check Packaging: Ensure the packaging is factory-sealed and free from moisture, rust, or impact damage.
Installation & Maintenance Tips
1. Cleaning
Thoroughly clean the shaft and housing. Remove any rust or burrs using fine sandpaper.
2. Proper Mounting
Use an induction heater (max 110°C) for installation. If using a mechanical press, use a bushing that matches the inner ring size.
3. No Direct Hammering
Never strike the outer ring, inner ring, or balls directly with a hammer, as this causes micro-damage that leads to premature noise.
Frequently Asked Questions
1) What are the dimensions of the 6212 bearing?
It has an inner bore of 60mm, an outer diameter of 110mm, and a width of 22mm (60x110x22 mm).
2) Why is C3 clearance recommended?
In heavy electric motors, heat causes shaft expansion. C3 clearance provides extra space, preventing the bearing from binding during thermal expansion.
3) Can I use direct flame for installation?
No. Open flames damage the rubber seals (2RS) and degrade the factory-packed grease. Use an induction heater only.
4) How do I verify FAGI bearing quality?
Look for clear markings on the rings, neat packaging, and purchase from reputable suppliers like KGICO.
Conclusion: Reliability for Your Production Line
