The 1615-6785-00 Atlas Copco OEM Drive Coupler is a Stromag Periflex-style flex gear coupling for Atlas Copco portable compressor platforms.
Flex gear couplings like the 1615-6785-00 use a different design principle than elastomeric couplers – they transmit torque through meshing gear teeth while accommodating misalignment through the flexibility of the gear mesh. This design is used in Atlas Copco compressors where the torque and speed requirements suit a gear-type coupling rather than an elastomeric element.
The 1615-6785-00 is a direct OEM replacement for the factory coupling. During installation, follow Atlas Copco’s service procedure including proper lubrication of the gear mesh if applicable, alignment verification, and torque specifications for all mounting hardware.
