AbolishedTest method for PV limit of plastics bearings
塑料轴承极限PV试验方法
Application Summary AI generated
This standard specifies a test method for determining the pressure-velocity (PV) limit of plastic bearings, which defines the maximum product of load and sliding speed before failure. It is applied in the design and material selection of unlubricated or self-lubricating plastic bearings used in mechanical systems, such as automotive components, office equipment, and light industrial machinery. The test evaluates thermal and mechanical limits under controlled conditions to ensure reliable performance in low-friction, dry-running applications.
