A Tradition of Excellence
NTN Corporation has built its reputation on producing bearings that combine cutting-edge technology with reliable performance. NTN bearings are widely used in automotive applications, industrial machinery, and precision equipment. They are known for their robust design and ability to withstand high loads and speeds.
Interpreting NTN Model Numbers
NTN’s part numbering system is methodical, much like its competitors, with each digit or letter in the sequence providing key product details. For example, an NTN deep groove ball bearing might be labeled 6001-2RS1 or include additional designations for precision or specialized seals. Key aspects include:
- Basic Series Number (e.g., 6001): Defines the bearing’s dimensions and general classification.
- Suffixes (e.g., -2RS1): Indicate the sealing type or any specialized modifications, such as internal clearance adjustments or special material coatings.
NTN also provides specialized designations for:
- Tapered Roller Bearings: With additional letters to signify variations in design for improved load distribution.
- Needle Roller Bearings: Which may include extra digits or letters to denote the bearing’s specific geometry and performance attributes.
Key NTN Series and Their Applications
- Deep Groove Ball Bearings: NTN’s standard series is widely used in applications ranging from small electric motors to large industrial machines. They offer excellent balance between load capacity and speed.
- Tapered Roller Bearings: Ideal for automotive applications (such as wheel hubs) and heavy-duty industrial equipment, these bearings excel in environments with combined radial and axial loads.
- Needle Roller Bearings: Perfect for compact applications where space is at a premium, these bearings are used in transmissions, pumps, and agricultural machinery.
- Spherical Roller Bearings: Designed for heavy loads and misalignment, NTN’s spherical bearings are often employed in mining equipment and large industrial drives.
