NTN Corporation is one of the world’s leading manufacturers of bearings, constant velocity joints, and precision equipment. Headquartered in Osaka, Japan, and established in 1918, NTN is globally recognized for high-performance, reliable, and durable bearing solutions across a wide array of industries. 🛠️ 1. Types of Bearings Offered by NTN NTN manufactures a broad range of bearing types, each engineered for specific applications and conditions: A. Ball Bearings Deep Groove Ball Bearings Most widely used type Supports radial and moderate axial loads Available in open, shielded (ZZ), or sealed (LLB, LLU) versions Angular Contact Ball Bearings Designed to handle combined axial and radial loads Typically used in pairs or sets Common in machine tools and pumps Self-aligning Ball Bearings Accommodates misalignment Used in applications with shaft deflection B. Roller Bearings Cylindrical Roller Bearings High radial load capacity Good for high-speed applications Tapered Roller Bearings Handle large radial and axial loads Common in automotive and heavy machinery Spherical Roller Bearings Accommodate misalignment and heavy loads Ideal for harsh environments like mining and steel mills Needle Roller Bearings High load capacity in compact space Widely used in transmissions and gearboxes C. Thrust Bearings Designed to support axial loads Includes thrust ball bearings, cylindrical roller thrust, and spherical roller thrust bearings D. Special Bearings Ceramic Bearings: High-speed, low friction, used in aerospace and precision equipment Insulated Bearings: Designed to prevent electrical erosion, ideal for electric motors 🌟 2. Key Features of NTN Bearings High-quality steel for extended service life Advanced sealing technology to prevent contamination Grease retention and lubrication options for reduced maintenance Precision and quiet operation (especially in electric motors) Corrosion-resistant variants for food, chemical, and marine industries ⚙️ 3. Applications NTN bearings are used across diverse sectors: Automotive (wheel hubs, transmission, A/C systems) Industrial Machinery Aerospace Agriculture Railways Wind and Renewable Energy Medical Equipment 🔢 4. NTN Bearing Numbering System NTN uses standardized and proprietary codes to describe bearing types and features. Example: 6206ZZC3 6206 = Deep groove ball bearing with 30 mm bore ZZ = Double shielded C3 = Internal clearance (greater than normal) Additional codes may indicate: Seal type (LLU, LLB, ZZ) Internal clearance (C3, C4) Tolerance class (P5, P6) Special materials or heat treatment (e.g., ET for case carburized steel) 🧪 5.
