Product Detail
Deep Groove Ball Bearing FAGI 6301 2RS C3 P6 Heavy Industrial Series | 12mm Bore | P6 Precision Class | C3 Thermal Clearance | Dual NBR Contact Seals (2RS)
Engineered to withstand higher radial and axial loads compared to standard light series; features P6 precision class for smooth and low-vibration performance, C3 internal clearance for thermal stability under heavy loads, and NBR rubber contact seals for complete protection against contaminants.
Technical Overview of FAGI 6301 2RS C3 P6
The FAGI 6301 2RS C3 P6 deep groove ball bearing belongs to the ISO 63 size family (heavy industrial series). Featuring heavier rings and larger rolling elements, it offers significantly higher radial and shock load-carrying capacity compared to equivalent bore models in the 62 or 60 series. This component is designed for shafts with a 12 mm diameter, an outer diameter of 37 mm, and a width of 12 mm.
The integration of P6 precision dimensional classes with C3 internal clearance and reinforced 2RS contact seals makes this bearing an ideal choice for sensitive industrial applications, high-pressure electric motors, industrial gearboxes, and machinery subjected to both heavy mechanical stress and demanding thermal environments.
Part Number Anatomy (FAGI 6301 2RS C3 P6)
First Digit (6): Indicates single-row radial deep groove ball bearings.
Second Digit (3): Represents the heavy industrial dimensional series (Series 03 / 63) featuring thicker cross-sections and exceptional load capacity.
Last Two Digits (01): Standard bore size code (01 = 12 mm), denoting a shaft diameter of 12 mm.
2RS (or 2RSR): Steel-reinforced rubber contact seals on both sides to completely prevent lubricant leakage and ingress of moisture and dust.
C3: Radial internal clearance greater than standard normal, optimized for operating conditions involving high temperatures and material expansion.
P6: Precision manufacturing class higher than normal grade to reduce vibration, minimize frictional loss, and extend operational longevity.
FAGI: A trusted brand of rotational mechanical components built with advanced metallurgical standards, supplied exclusively by Kamyar Gostar Iranian (KGICO).

Engineering Comparison: Series 6301 vs. Series 6201 (Equivalent 12mm Shaft Diameter)
Evaluating structural differences for 12mm shafts:
| Bearing Model | Dimensions (Outer Dia × Width) | Load Capacity | Shock Load Resistance | Primary Application |
|---|---|---|---|---|
| 6301 (Heavy Series) | 37 × 12 mm | Very High (Thanks to larger balls and thicker rings) | Excellent | Alternators, heavy industrial equipment, industrial power tools, high-pressure pumps. |
| 6201 (Light Series) | 32 × 10 mm | Moderate | Standard | Light home appliances, electronic equipment, and shafts with limited radial loads. |
Key Engineering Advantages & Value Proposition

C3 Thermal Clearance
Prevents binding or unwanted pre-load stresses during high thermal fluctuations and heavy interference fits.
100Cr6 Alloy Steel
Through-hardened uniformly up to 60-64 HRC for exceptional resistance against material fatigue and surface spalling.
KGICO Authenticity Guarantee
Expert technical support, precise dimensional control, and authentic quality assurance provided by Kamyar Gostar Iranian.
Primary Industrial & Mechanical Applications
- Automotive & Industrial Alternators & Starters: Withstanding high rotational loads and continuous vibration in engine compartments.
- Heavy Industrial Power Tools: Angle grinders, bench grinders, and industrial hammer drills featuring high-stress 12mm shafts.
- Specialized Water Pumps & Electric Motors: Applications requiring a 12mm shaft due to space constraints yet demanding high radial load capability.
- Small Industrial Gearboxes: Intermediate shafts requiring bearings resistant to shock loads.
Installation Guidelines & Engineering Warnings
When fitting the bearing onto the 12mm shaft, apply pressing force only to the face of the inner ring. If fitting the component into a housing or bore, concentrate the pressure on the outer ring. Never transmit force through the rolling elements (balls), as this causes localized raceway indentation (Brinelling) and premature failure.
Ensure installation tools do not damage the 2RS rubber seal lip; harming the seal edge will lead to lubricant leakage and contaminant ingress. Avoid submerging sealed bearings in aggressive industrial solvents that degrade the NBR polymer structure.
Recommended Techniques for Size 6301
Considering fitting interferences in motor and power tool shafts, the use of precision mechanical or hydraulic presses equipped with aligned mounting sleeves is strongly advised to prevent angular damage to the rings.
Frequently Asked Questions (FAQ)
1. What is the main difference between the 6301 and 6201 bearings?
Both models share a 12mm shaft diameter, but the 6301 belongs to the heavy series and features a larger outer diameter (37mm vs. 32mm) and greater width, providing vastly superior load capacity and durability under harsh conditions.
2. What is the advantage of the P6 precision class in this bearing?
The P6 precision class provides significantly tighter dimensional tolerances than standard grade, reducing machinery vibration while substantially enhancing mechanical efficiency and service life.
3. Does this bearing require initial grease replenishment?
No; this bearing is factory-packed with an optimal quantity of high-grade grease and comes fully sealed, requiring no lubricant maintenance throughout its operational lifespan.
