| Code Segment | Technical Meaning |
|---|---|
| 3204 | Basic bearing designation: Double Row Angular Contact Ball Bearing, 20mm bore, 47mm OD, 20.6mm width |
| A | Contact angle of 30°, optimized for carrying significant axial loads |
| 2RS1 | Bearing fitted with rubber seals on both sides for effective protection against contaminants |
3204 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support substantial combined radial and axial loads from both directions, enhancing stability in demanding applications.
Sealed & Lubricated for Life: The 2RS1 rubber seals effectively shield the internal components from dust, moisture, and other contaminants. Combined with factory-applied high-performance grease, this ensures reliable operation and a long service life without the need for re-lubrication.
Precision & Speed Performance: Built to P6 tolerance class with a stainless steel cage, the bearing maintains precision under high-speed conditions, with a limiting speed of 10,000 rpm. The optimized internal geometry contributes to smooth running and low heat generation.
Durable Material Construction: Manufactured from chrome steel for rings and balls, and stainless steel for the cage, the bearing offers excellent resistance to wear and corrosion, ensuring consistent performance across its operating temperature range of -30°C to 110°C.
