NSK Single Row Deep Groove Ball Bearing 17 mm ID, 47 mm OD, 14 mm Width, Steel Cage & Balls, Sealed, Model 6303DDUC3

NSK 6303DDUC3 is a single row deep groove ball bearing featuring a 17 mm inside diameter, 47 mm outside diameter, and 14 mm race width. It employs a steel cage and steel balls, sealed on both sides with synthetic rubber seals (type DDU) to protect against lubricant leakage and contaminants such as dust and water. This bearing type is engineered to sustain both radial and axial loads efficiently, making it ideal for a variety of industrial machinery and mechanical applications.

The internal clearance is rated as C3, providing extra radial internal clearance necessary for conditions involving heat expansion or high-speed operation. With a static load rating of 6.65 kN and a dynamic load rating of 13.6 kN, this bearing is suitable for medium duty applications commonly found in manufacturing, conveyor systems, and other mechanical power transmission tasks.

The bearing design incorporates a parallel bore type facilitating straightforward mounting and integration within shafts and housings. As part of NSK's 3 Medium series, this bearing balances performance and durability for medium load applications.

The sealed construction with 2 synthetic rubber contact seals (DDU type) helps maintain bearing cleanliness and lubrication over extended service life. This feature is critical in environments exposed to dust, moisture, or other contaminants.

Steel cage and balls ensure strength and wear resistance. Seals prevent ingress of dirt and lubricant loss. Accepts combined radial and axial loads. Internal clearance class C3 for precision and heat tolerance. Medium duty series suited for broad industrial uses.

Parallel bore for ease of mounting. Durability ensured by high static and dynamic load ratings.

This NSK 6303DDUC3 Ball Bearing serves a wide range of applications in industrial tools, manufacturing equipment, and mechanical power transmission. Its sealed design and robust steel construction make it a reliable choice for long-term performance in demanding environments.
