Product Detail
Deep Groove Ball Bearing KGI 6410 Extra Heavy Industrial Series | 50mm Bore | Maximum Dynamic Load & Shock Resistance
An engineering masterpiece from the 64 series featuring maximum ring thickness and exceptionally large rolling elements; engineered for the harshest heavy-duty industrial applications, extreme concentrated radial loads, and continuous vibrations under the strict quality control of Kamyar Gostar Iranian (KGICO).
Technical Overview of KGI 6410
The KGI 6410 deep groove ball bearing belongs to the rarest, most robust, and powerful family of deep groove bearings: the 64 Series (Extra Heavy Series). Designed for shafts with a 50 mm diameter, it features an impressive outer diameter of 130 mm and a width of 31 mm, offering a significantly bulkier body and vastly superior physical strength compared to 60, 62, and 63 series bearings.
Engineers turn to the 64 series when facing severe shock loads, crushing dynamic forces, and harsh environmental conditions where standard bearings would quickly suffer from premature surface fatigue (flaking) or ring fracture. The KGI brand utilizes ultra-pure alloy chrome steel (100Cr6) combined with precision heat treatment to guarantee maximum mechanical strength and dimensional stability under intense operating conditions.

Technical Specifications & Boundary Dimensions
| Bore Diameter (d) | Outer Diameter (D) | Width (B) | Structural Series | Load Capacity | Shock Resistance | Approx. Weight | Material Alloy |
|---|---|---|---|---|---|---|---|
| 50 mm | 130 mm | 31 mm | Extra Heavy Deep Groove (Series 64) | Very High (Dynamic & Static) | Exceptional against sudden impacts | ~1.95 kg | 100Cr6 Chrome Alloy Steel (Uniform Hardening) |
Engineering Comparison: Why Series 6410 Stands Out (Equivalent 50mm Shaft Diameter)
To understand the engineering strength of the 6410 bearing, evaluate its dimensional and mass specifications against other 50mm shaft series:
| Bearing Model | Weight Class | Dimensions (d × D × B) | Approx. Weight | Dynamic Load Capacity | Primary Application Area |
|---|---|---|---|---|---|
| 6010 | Extra Light | 50 × 80 × 16 mm | ~0.26 kg | Low / Suitable for very high speeds | Compact radial spaces |
| 6210 | Light | 50 × 90 × 20 mm | ~0.46 kg | Standard Industrial | General electric motors |
| 6310 | Heavy | 50 × 110 × 27 mm | ~1.07 kg | Very Good | Industrial pumps and gearboxes |
| 6410 (KGI) | Extra Heavy | 50 × 130 × 31 mm | ~1.95 kg (Approx. 2x of 6310!) | Maximum in Deep Groove Class | Vibrating equipment, crushers, massive fans, severe shock loads |
Key Engineering Advantages & Value Proposition
Extra-Thick Ring Walls
Reinforced internal and external steel ring bodies prevent deformation, cracking, or failure under abnormal stresses.
Maximum Size Rolling Elements
The use of extra-large balls increases effective contact surface area, maximizing torque handling and heavy radial load capacity.
Unrivaled Shock Load Resistance
Due to high mass and ideal metallurgical hardness, sudden shocks and mechanical impacts on production lines will not damage raceways.
Dimensional Stability in Harsh Conditions
100Cr6 steel with specialized tempering preserves metallurgical structure stability under continuous industrial temperatures and loads.
Robust Ball Guide Cage
Equipped with a sturdy riveted steel or machined brass cage ensuring orderly ball movement and optimal lubrication flow.
KGI Authenticity & Quality Assurance
Comprehensive dimensional checks and metallurgical testing under the direct supervision of Kamyar Gostar Iranian with sustainable performance warranty.
Primary Industrial Applications
- Mining Crushing & Screening Machinery: Industrial screens, stone crushers, and vibrating feeders subjected to constant vibration and heavy impact loads.
- Heavy Industrial Gearboxes & Reducers: High-pressure input or intermediate shafts operating under torque and crushing radial loads.
- Massive Centrifugal Blowers & Fans in Steel and Cement Plants: Supporting high impeller weight and preventing radial runout.
- Heavy Woodworking & Processing Machinery: Gatler saws, rolling mill tension rollers, and continuous power transmission equipment.
- Massive Piston & Hydraulic Injection Pumps: Absorbing shocks caused by water hammer and sudden fluid pressure fluctuations.
Installation Guidelines & Engineering Warnings
Due to heavy ring thickness and severe interference fit requirements on a 50mm shaft, never use hammers or direct levers. The standard mounting method for this bearing is using an induction heater up to a maximum temperature of 110°C to 120°C, allowing the inner ring to expand smoothly and seat easily onto the shaft journal.
Due to its large ball dimensions and ring volume, the 6410 bearing requires a high-viscosity lubricating film (oil or lithium-base greases with EP additives for extreme pressure). Ensure the housing cavity is filled and rotates smoothly prior to initial startup.
Golden Rule of Force Application During Cold Assembly
If using a hydraulic press, force must be applied exclusively to the ring with the interference fit (on shaft: inner ring | in housing: outer ring). Transmitting press force through the rolling elements will cause raceway indentation (Brinelling), resulting in abnormal noise and premature failure.
Frequently Asked Questions (FAQ)
1. What is the main difference between the 6410 and 6310 bearings?
Both bearings share a 50mm shaft diameter, but the 6410 features a larger outer diameter (130mm vs. 110mm), greater width (31mm vs. 27mm), and approximately double the weight of the 6310, providing a dramatic increase in load capacity and impact resistance.
2. Is the 6410 bearing suitable for very high rotational speeds?
Due to its heavy rolling elements and high inertia, the 64 series is optimized for heavy loads and moderate-to-low speeds. For applications requiring exceptionally high speeds, lighter series such as 6010 or 6210 are preferred.
3. Is this bearing available in sealed versions (2RS / ZZ)?
Because of its heavy industrial housing placement, the 64 series is typically used in open format operating within oil baths or housing grease; however, custom variants can be supplied upon special project inquiry via Kamyar Gostar Iranian.
