3204 2RS ZEN 20x47x20.6 mm Angular Contact Ball Bearing

High-Quality Bearing for Precision and Durability

The 3204 2RS ZEN Angular Contact Ball Bearing (20x47x20.6 mm) is a robust and precision-engineered component designed for demanding industrial and mechanical applications. Manufactured by ZEN Bearings, this model combines high durability, precision alignment, and reliable sealing, ensuring smooth operation even under heavy loads and variable conditions.

This sealed double-row angular contact bearing features the 2RS type rubber seals on both sides, effectively protecting the bearing from dust, moisture, and lubricant loss. Its angular contact design allows it to carry both radial and axial loads, providing excellent performance in motors, gearboxes, and units requiring high stiffness and long service life.

Applications

The 3204 2RS ZEN bearing is widely used in industrial machinery, agricultural equipment, electric motors, pumps, and transmission systems. Its versatility makes it suitable for:

• Bearing housings and bearing units that demand precise alignment and stability.

• Machine tools and gear systems requiring minimal maintenance and low friction.

• Heavy-duty drive systems where high rotational accuracy and load-bearing capacity are critical.

• Industrial applications exposed to contaminants, where sealed bearings significantly extend operational life.

Advantages

• Double-row angular contact design - supports combined loads (radial and axial) in both directions, ensuring high stiffness and precision.

• 2RS sealing system - rubber seals on both sides prevent ingress of dust and moisture while retaining grease.

• Compact dimensions (20x47x20.6 mm) - ideal for compact bearing assemblies and units.

• High durability and resistance to wear - reliable under continuous load, vibration, and speed variation.

• ZEN quality assurance - European engineering standards ensure consistent performance and cost-effective operation.

FAQ

1. What does “2RS” mean in the bearing code?
“2RS” indicates rubber seals on both sides of the bearing, providing full protection from contaminants and preventing lubricant leakage.

2. What are the main advantages of an angular contact bearing compared to a deep groove bearing?
Angular contact bearings can handle both radial and axial loads simultaneously, providing higher rigidity and longer life in precision applications.

3. Can 3204 2RS bearings be used in high-speed applications?
Yes. Thanks to their optimized contact angle and sealing design, they maintain stability and lubrication even at elevated speeds.

4. What type of lubrication is used in ZEN 3204 2RS bearings?
They come factory pre-lubricated with high-performance grease, requiring minimal maintenance throughout their operational life.

5. How can I ensure the correct fit for a bearing housing or shaft?
Measure the shaft diameter (20 mm) and housing bore (47 mm) to confirm compatibility. Ensure proper press fit and avoid excessive misalignment during installation.
