NTN Bearing Cross Reference Chart and Interchange Guide
In the global bearing market, there are many brands and model numbers, and bearings from different brand manufacturers vary in size, material, structure and performance. Therefore, quickly finding replacement equivalents for the corresponding bearing model has become an important issue. Understanding cross-reference tables and interchange guides for bearings is critical for mechanical engineers and maintenance personnel. This article will detail the cross-reference table and interchange guide for NTN bearings to help engineers and technicians provide a reference when they need to replace or find equivalent models.

ToggleIntroduction to NTN bearings
NTN is one of the world’s leading bearing manufacturers, founded in 1918 and headquartered in Japan. NTN bearings are known for their high precision, high performance and high reliability, and are widely used in automobiles, aerospace, machine tools, mining equipment, heavy machinery and other fields. NTN’s product lines include deep groove ball bearings, tapered roller bearings, cylindrical roller bearings, aligning ball bearings, thrust bearings and other types.

Bearing model naming rules
NTN bearing model naming rules usually consist of a set of letters and numbers, representing the type, size, structure and characteristics of the bearing. For example, the model number is 6205, where “6” represents the deep groove ball bearing, “2” represents the series, and “05” represents the inner diameter of the bearing is 25mm. In addition, there are some letter suffixes used to indicate special characteristics of the bearing, such as C3 for large internal clearance, LLB for non-contact with rubber seals, etc.

Bearing Interchange Guide
In actual applications, bearing interchange should not only consider the model, but also pay attention to some key parameters such as size, tolerance, internal structure and material. Here are some key considerations:
Size Matching
The inner diameter, outer diameter and width of the bearing are the most basic parameters. When interchanged, it is necessary to ensure that the size is completely matched, otherwise it will affect the installation and operation. For example, the inner diameter of the 6205 bearing is 25mm, the outer diameter is 52mm, and the width is 15mm. If the size of the replacement bearing is inconsistent, it will not be installed normally.
Tolerance and clearance
The tolerance and clearance of the bearing directly affect its running performance and life. Tolerances indicate the manufacturing accuracy of the bearing components, while clearances indicate the internal clearance of the bearing. Different applications have different requirements for tolerances and clearances. When interchanging, ensure that the tolerances and clearances of the new bearings are similar to those of the original bearings.
Materials and lubrication
The bearing material and lubrication method also affect its performance and life. NTN bearings are usually made of high-carbon chromium bearing steel, which has excellent wear resistance and fatigue resistance. When interchanging, ensure that the material and lubrication method of the new bearing are the same or similar to those of the original bearing.
Load and speed
The rated loads and allowable speeds of different bearing models are different. When selecting a replacement model, ensure that the rated load and allowable speed of the new bearing are not lower than those of the original bearing to ensure the normal operation of the equipment.
Bearing Interchange Case Analysis
Case 1: A certain automobile wheel hub bearing is damaged and needs to be replaced. The original model is NTN 6205LLB, and SKF 6205-2RSH is found as an alternative model through the cross-reference table. When interchanging, it is necessary to check the size, tolerance, clearance and seal form of both. 6205LLB means the bearing has double-sided rubber seals, while 2RSH means the bearing has double-sided contact seals. The two are slightly different in sealing form, but the basic performance is similar and can be used interchangeably.
Case 2: Interchange of machine tool spindle bearings
The spindle bearing of a machine tool needs to be replaced. The original model is NTN 7204B. FAG 7204B.TVP is found as an alternative model through the cross-reference table. When interchangeable, it is necessary to focus on the accuracy grade and clearance of the two. 7204B means angular contact ball bearing, with an accuracy grade of P5, suitable for high-speed and high-precision occasions. After the interchange, a trial run is required to ensure that the performance of the new bearing meets the requirements.
Conclusion
Through the introduction of the NTN bearing cross-reference chart and interchange guide in this article, engineers and technicians can quickly find a suitable replacement model when they need to replace bearings. In practical applications, in addition to paying attention to model matching, key parameters such as size, tolerance, clearance, material and load should also be paid attention to to ensure the normal operation of the equipment and extend the service life of the bearing. The selection and interchangeability of bearings is a systematic project that requires comprehensive consideration of specific applications and working conditions. I hope this article can provide readers with valuable references and help solve problems in actual work.
