Introduction to NTN Oil Retaining Bearings

NTN Oil Retaining Bearings are engineered to deliver long-lasting performance with minimal maintenance. By utilizing oil-impregnated porous metal structures, these bearings provide continuous lubrication during operation. This self-lubricating design reduces friction, extends service life, and ensures reliable performance across demanding industrial environments.

Key Design Features and Advantages

· Self-Lubricating Technology – Porous bearing material absorbs and retains oil, enabling automatic lubrication throughout operation.

· Reduced Maintenance Costs – No frequent re-lubrication required, lowering downtime and maintenance expenses.

· High Wear Resistance – Strong alloy structure enhances durability under heavy loads and extended use.

· Thermal and Load Stability – Consistent performance under variable temperature and load conditions.

· Low Noise Operation – Smooth motion makes them suitable for applications requiring quiet, precise operation.

Size Range and Specifications

NTN Oil Retaining Bearings are available in multiple size ranges, covering both metric and inch series. Standard bore diameters typically range from 6 mm to 100 mm, with the option for custom dimensions to match specific equipment designs. This wide availability ensures compatibility across a broad spectrum of machinery.

Industry Applications

· Automotive – Starters, alternators, wiper motors, and small electric components.

· Home Appliances – Fans, washing machines, and compact electric motors.

· Textile & Paper Machinery – Continuous lubrication supports high-speed production.

· Industrial Equipment & Power Tools – Long life cycle and stable performance under high loads.

· Food Processing & Packaging – Clean lubrication reduces contamination risk.
