NSK Single Row Deep Groove Ball Bearing, Sealed, Steel Cage and Balls, 45 mm ID, 100 mm OD, 25 mm Width 6309DDU

NSK 6309DDU is a high-quality single row deep groove ball bearing designed for industrial, mechanical, and fluid power applications. This bearing features a sealed design with two synthetic rubber contact seals (DDU) to effectively prevent ingress of dust, water, and other contaminants, ensuring extended lubrication retention and bearing lifespan.

It has an inside diameter of 45 mm, outside diameter of 100 mm, and a race width of 25 mm. The cage and balls are made of durable steel, providing robust performance under both radial and axial loads. The bearing has a dynamic load rating of 53 kN and a static load rating of 32 kN, making it suitable for medium-load applications.

The internal clearance level is CN (normal), and it uses a parallel bore type to facilitate precise shaft fitting. The race type is plain, which helps maintain smooth rotation and reduces noise and vibration during operation. The bearing belongs to the 3 Medium series, balancing size and load capacity for versatile use.

This sealed ball bearing is ideal for various industrial uses such as machinery manufacturing, automotive assemblies, agricultural equipment, HVAC systems, and general mechanical engineering.

Key features include the sealed construction with synthetic rubber seals, high-quality steel materials, capability to withstand radial and axial forces, and design optimized for durability and maintenance ease.

Designed to accept both radial and axial loads for versatile applications. Equipped with two synthetic rubber seals to prevent lubricant leakage and ingress of contaminants. Constructed with steel cage and steel balls for strength and longevity.

Features a 25 mm race width suitable for medium-duty load scenarios. Internal clearance CN ensures accurate fit and smooth operation. Parallel bore type for easy mounting and reliable shaft fitment. Dynamic and static load ratings of 53 kN and 32 kN respectively for dependable performance.
