Applications & Industrial Use
The SKF 6204 ZZ C3 GJN is a deep groove ball bearing featuring double metal shields (ZZ), enhanced internal clearance (C3), and premium grease fill (GJN). With dimensions 20 mm bore x 47 mm outer diameter x 14 mm width, it is widely used in industrial sealing, rotational systems, and mechanical assemblies requiring durable, low-friction support.
This bearing unit is suitable for hydraulic motors, gearboxes, electric motors, fans, pumps, transmission systems, and other industrial applications where a compact, shielded, and high-precision rolling bearing is needed. Its construction allows stable performance under radial loads, occasional axial loads, and moderate speeds, while shielding protects against contamination.
Key Features & Benefits
-
Double-metal shielding (ZZ) on both sides protects internal components from dust and solid particles, retaining lubricant and increasing service life.
-
C3 internal clearance offers additional axial and radial play, accommodating thermal expansion and high-speed operation without binding.
-
GJN grease fill indicates factory lubrication optimized for operational stability, reducing maintenance requirements and ensuring consistent performance.
-
Robust construction and high durability: premium bearing steel and precise manufacturing provide reliable performance under load, vibration, and moderate shock.
-
Low friction & quiet operation: deep groove design reduces drag and vibration, facilitating smooth rotation for precision equipment.
-
Compact dimensions allow integration into tight assemblies and standard bearing housings (bearing blocks or casings) without redesign.

FAQ - Common Questions & Answers
1. What does “ZZ C3 GJN” signify?
-
ZZ = double metal shields, protecting both sides.
-
C3 = increased internal clearance, which allows for thermal expansion and higher speed tolerance.
-
GJN = factory grease specification, meaning the bearing comes pre-lubricated for service use.
2. Why is C3 clearance used instead of standard?
C3 clearance is employed when bearings operate at elevated temperatures or high speeds, or when dimensional changes may occur. It prevents the bearing from binding under these expansions.
3. Are shielded bearings suitable in harsh environments?
Yes—with metal shields (ZZ), these bearings resist dust and light contamination. They are suited for industrial environments, though not for immersion or heavy slurry exposure.
4. What loads can this bearing support?
As a deep groove bearing, it primarily handles radial loads, but it can also support modest axial loads in both directions. Exact load capacities depend on the operating conditions and installation.
5. When can I receive it?
