What is non-standard bearing?
Non-standard bearings, generally speaking, are bearings that do not conform to the overall dimensions specified in the national standard, that is, all bearings with different overall dimensions from those specified in the national standard.
Its main characteristics are: low versatility, mostly used for special equipment and special occasions, and the majority of small batch, new research and development; D. Trial production of equipment; However, due to its non-scale and mass production, there are not many manufacturers, so the cost is high and the price is expensive.
The inner diameter or outer diameter, width (height) and size of the standard bearing shall comply with the bearing dimensions specified in GB/T 273.1-2003, GB/T 273.2-1998, GB/T 273.3-1999 or other relevant standards.

Non-standard bearings refer to bearings that do not match the size and structure of standard bearings, that is, bearings produced according to customer requirements. For example, non-standard internal and external 49 and standard 50 are the same. So 49 is non-standard. You have to follow the size and structure proportion in the customer's book, otherwise you will know whether 49 is the national standard or 50. There are also different structures. For example, some steel ball rollers are more or less. This rare material can generally be called non-standard bearing.
1. Features:
(1) Low versatility, mostly used for special equipment, special occasions, small batch, new
(2) Products used for research and development; D Equipment accounts for the majority; However, due to its non-scale and mass production, there are not many manufacturers, so the cost is high and the price is expensive.
2. Standard bearing:
The inner diameter or outer diameter, width (height) and size of the standard bearing shall comply with the bearing dimensions specified in GB/T273.1-2003, GB/T273.2-1998, GB/T273.3-1999 or other relevant standards.
3. Non-standard bearings are standard bearings.
Non-standard bearings are bearings that do not match the size and structure of standard bearings, that is, bearings produced according to customer requirements.
For example:
(1) Non-standard internal and external 49, standard 50, all the same. Then 49 is non-standard, which needs to be based on the size and structure proportion in the customer's book. Otherwise, whether 49 is a national standard or not is unknown.
(2) Other structures are different. For example, some steel ball rollers are more or less. This rare material can generally be called non-standard bearing.
