INA Bearings and engine components
INA is another division of the Schaeffler Group and was founded in
1946. They supply Mercedes-Benz with a wide range of bearings pulleys and
engine components.
INA pioneered the Hydraulic variable cam timers that Mercedes-Benz
introduced on the M104 engine in 1990.
Pictured here is the casting mark on a drive belt pulley support for an
