MAIN AND PINION SHAFT
Shaft is made of special alloy steel machined to close accuracy and fitted in bronze bushes for smooth working, longer life and accuracy. Gears: Gears are of steel cast or fabricated. Gear teeth are generated by precision hobbing machine.
AUTO LUBRICATION SYSTEM
The auto lubrication system with default monitor ensures high reliable operation.
GEARS
Gears are of steel cast of fabricated. Gear teeth are generated by precision hobbing machine.
PNEUMATIC DRY CLUTCH
The fail-safe, pneumatically operated clutch brake combination is designed to provide excellent slide motion control even at high speeds. Adequate energy required for blanking operation is ensured by optimised design of the flywheel.
DUAL SAFETY VALVE
