Gear machining accuracy grade comparison table (AGMA, DIN, JIS, ISO, etc.)

The comparison table of gear machining accuracy grades such as American standard AGMA, German standard DIN, Japanese standard JIS, international standard ISO is as follows, for reference and understanding, unclear places or relatedGear processingIf you need, you can consult EP for free.

Comparison table of different international gear machining accuracy grades

Reminder: Take the German DIN standard as an example. There are 1-12 accuracy grades. The smaller the number, the higher the gear accuracy. Other standards can be matched according to this table.The accuracy level of the gear should be determined according to the purpose of the transmission, use conditions, transmission efficiency and circumferential speed, as well as other economic and technical indicators. If you are unclear, you can ask the EP technician for help.
