The standards for tapered roller bearings involve multiple aspects, including size, quality, performance, and testing methods. The following are some common standards for
tapered roller bearings:
1. ISO 355: This standard was developed by the International Organization for Standardization (ISO) and specifies the size series, external dimensions, tolerances, lubrication
requirements, and test methods of tapered roller bearings. The IS0355 standard divides tapered roller bearings into multiple series and provides detailed specifications.
2. ANSI/ABMA Standards: The American Bearing Manufacturers Association (ABMA) has issued a series of standards, including ANSI/ABMA 19.2 and ANSI/ABMA 19.1, to
standardize the dimensions, tolerances, quality control, and performance requirements of tapered roller bearings.
3. DIN standards: The German National Standards Institute (DIN) has also issued some standards, such as DIN720 and DIN ISO 355, to regulate the size and tolerance
requirements of tapered roller bearings.
4. GB/T standards: The National Organization for Standardization (SAC) of China has issued a series of standards, such as GB/T307.1 and GB/T 297, to standardize
the dimensions, tolerances, quality control, and test methods of tapered roller bearings.
It is necessary to select applicable standards for the design, manufacturing, and selection of tapered roller bearings based on specific applications and needs. It is
recommended that you refer to relevant international, national, or industry standards when purchasing or using tapered roller bearings to ensure that the quality
and performance of the product meet the requirements.
