5206RS Sealed Ball Bearing 30x62x23.8 Angular Contact 2RS by Nsk

Description

Product Overview

The 5206RS sealed ball bearing is engineered by Nsk to meet demanding industrial standards. With a 30 mm inner diameter, 62 mm outer diameter, and a width of 23.8 mm, this bearing provides a compact yet robust solution for high‑speed rotational applications. Its angular contact geometry allows it to handle both radial and axial loads efficiently, while the double‑sealed (2RS) design prevents ingress of dust, moisture, and other contaminants, extending service life and reducing maintenance intervals. Constructed from high‑grade chrome steel, the bearing offers excellent hardness, wear resistance, and fatigue strength, ensuring consistent performance even under fluctuating temperature conditions. The precision‑ground raceways and uniformly distributed steel balls contribute to smooth operation, low vibration, and reduced noise, making the 5206RS an ideal choice for precision machinery, gearboxes, and power transmission equipment.

Usage

This bearing is suited for a wide range of industrial environments. It excels in high‑speed motor shafts, spindle drives, and precision tooling where both radial and axial forces are present. The sealed configuration makes it appropriate for dusty or humid settings such as manufacturing floors, automotive assembly lines, and outdoor power generation units. Engineers often select the 5206RS for applications that demand reliable operation over long periods without frequent lubrication checks, including conveyor systems, pumps, compressors, and robotic joints. Its compact dimensions enable integration into tight mechanical assemblies, while the angular contact design ensures stability under combined loading, reducing the risk of premature wear or misalignment.

Why Choose Us

Choosing the Nsk 5206RS bearing means selecting a product backed by rigorous quality control and decades of bearing manufacturing expertise.

FAQ

What does the 2RS designation mean?

2RS indicates that the bearing has two rubber seals—one on each side—to prevent contaminants from entering and to retain lubrication inside the bearing.

Can this bearing be used in high‑temperature environments?

Yes, the bearing’s chrome steel material and sealed design allow operation up to approximately 120 °C (248 °F) when properly installed, making it suitable for many industrial temperature ranges.

Is additional lubrication required for the 5206RS bearing?

No external lubrication is needed. The internal lubrication is sealed within the bearing, providing long‑term performance without routine greasing.

What load ratings does the 5206RS support?

The bearing is rated for dynamic radial loads up to 2,800 N and axial loads up to 1,200 N, depending on operating speed and temperature, as defined by ISO 281 calculations.

How do I ensure proper installation?

Follow Nsk’s installation guidelines: clean the shaft and housing, avoid impact loading, use a proper bearing press, and verify that the bearing sits flush without axial play. Proper alignment and handling prevent premature wear.
