Agricultural ball bearings may be affected by the following factors:
Material
This is not a simple "GCr15" that can distribute everything. Steel quality varies from mill to mill.
craft
Even though a factory may have a different process, just doing it slowly or faster will make a difference.
design
Drawings vary, and when it comes time to try to save costs, there are more derivatives
equipment
Includes repairs, including heat treatment equipment, turning, grinding, superfinishing, cleaning, automated assembly
worker experience
Chinese workers are not as rich as they were a few years ago and wages have risen a lot, but al all factories still lack experienced workers
Quality testing equipment
different standard parts,
manage
It's an attitude towards quality control, not simply an ISO certificate that can be easily "purchased"
Part quality
This is very important for agricultural ball bearings, balls, rollers, cages, seals, greases, and even anti-rust oils.
It's not a standard, P0 (or ABEC-1, Z1, etc.) can tell you everything about the quality of agricultural ball bearings. Same as "GCr15" does not represent material. Many factors affect the quality of agricultural ball bearings. And usually, a combination of factors leads to the failure of agricultural ball bearings.
In terms of average demand, more than 80% of the total global demand for agricultural ball bearings can be replaced by Chinese agricultural ball bearings.
