China National Technical Committee on Plain Bearings: Part National Standards Under Development for Plain Bearings
As of now, China has issued national standards for sliding bearings. These standards cover multiple fundamental areas such as materials, terminology, dimensional tolerances, and performance testing for sliding bearings.
At the same time, multiple standards are being developed/revised, involving areas such as sliding bearing fatigue and shell support. The following are the national standards being drafted by the National Sliding Bearing Standardization Technical Committee for the direction of sliding bearings:

MG-1A Aluminum matrix composite bearings：
MG-1A is a composite material of PTFE compound tape on aluminum shell, the PTFE is tape up to 0.20 mm thickness, enabling the bearing can be sized after being fixed, meanwhile the thick PTFE layer isolates noise. The bearing is widely applied in OA machinery, shock absorber for light design bicycle.
