Introduction of Non Standard Bearings

Non-standard bearings are bearings that do not conform to the external dimensions specified by the national standards, that is, the external dimensions are different from all bearings specified by the national standards.

Its main characteristics are low versatility, mostly special equipment, special occasion applications, small batches, and new research and development equipment trial products accounted for the majority; but because of its non-scale and batch production, there are not many manufacturers and the cost is high , The price is more expensive.

The inner or outer diameter, width (height) and dimensions of standard bearings conform to the outer dimensions of the bearing specified in GB/T 273.1-2003, GB/T 273.2-1998, GB/T 273.3-1999 or other relevant standards.

Non-standard bearings are bearings that are not compatible with the standard bearing size structure, that is, bearings produced according to customer requirements. Non-standard internal and external 49 standard 50, everything else is the same. Then 49 is a non-standard. You have to compare the size and structure in the customer book, otherwise you know whether 49 is the national standard or 50.

ZZ BEARINGS are Non Standard Bearings Manufacturers can also produce other different non-standard bearings, such as non-standard materials (such as ceramic bearings, stainless steel bearings, plastic bearings) , non-standard shapes (U-slot bearings, U-slot bearings, arc bearings), and work at High Temperature Bearings (150 ° high temperature bearing, 200 ° high temperature bearing, 250 ° high temperature bearing, etc.).
