6418 Deep Groove Ball Bearing Heavy Duty Design for Industrial Motors and Pumps | 90×225×54 mm

The 6418 is a single-row deep groove ball bearing with an open design, engineered for heavy-duty industrial applications requiring high load capacity and reliable performance. Featuring a 90 mm bore, 225 mm outer diameter, and 54 mm width, this bearing accommodates substantial radial loads as well as bidirectional axial loads. Its open configuration allows for easy relubrication, making it ideal for high-speed operations, elevated temperatures, or environments where maintenance intervals require periodic lubrication. Manufactured from premium chrome steel, the 6418 ensures long service life under demanding conditions.



6418 Deep Groove Ball Bearing 90×225×54 mm | ISO 64 Series – Heavy Duty | Open Design (Unsealed)

This bearing handles moderate to heavy radial loads and light to moderate axial loads from both directions. With a dynamic load rating of 186 kN and a static load rating of 150 kN, it delivers robust performance in industrial machinery. The 6418 achieves a reference speed of 6,700 r/min (oil lubrication) and a limiting speed of 4,300 r/min (grease lubrication), making it suitable for a wide range of rotating equipment including electric motors, pumps, gearboxes, and conveyors.

Key Performance Features

01. High Load Capacity & Durability

Designed with optimized internal geometry and robust chrome steel construction, the 6418 delivers exceptional radial and axial load ratings. Its large cross‑section and precision‑ground raceways ensure reliable performance under heavy loads and shock conditions.

02. Open Design for Flexible Lubrication

The open configuration permits direct lubrication of the rolling elements, allowing users to select the optimal grease or oil for their specific operating conditions. This flexibility extends bearing life in high‑speed or high‑temperature applications where re‑lubrication is required.

03. Precision Manufacturing for Smooth Operation

Manufactured to standard P0 precision class, the 6418 features tightly controlled tolerances, quiet running characteristics, and low vibration. This makes it suitable for general industrial applications where consistent performance and minimal noise are valued.
