1) Crank shafts are available for both the type
of compressor that is Air cooled & Water
cooled
unit.
2) Crank shaft for Air cooled compressors
rotates on heavy duty ball Bearings which are
hydraulic
pressed with axial
alignment. These Crank shaft
are dynamic balanced for vibration free working of unit & properly drilled for
mounting of
centrifugal unloaders to release pressurised Air
/ Gas from Intercoolers during unload position.
3) Forged heavy duty Crank shafts are for water
cooled heavy duty compressors. These crank
shaft are machined
and ground on Main Bearing
Journal & crank pin Journal by maintaining diameteral tolerance and axial tolerance
perfectly with main Bearing bushing & crank pin
bushing. Also Internally perfectly drilled for
oil path for proper
lubrication & to maintain
oil pressure.
