Kubit Head Shaft Pulley (Pulley Head Shaft Kubit) is one of the critical components in the power transmission system of Kubit impact crushers (such as HS and NS models) manufactured by Novincsm. This component plays a key role in coupling the electric motor to the rotor.

This circular pulley, equipped with belt grooves, transfers torque from the motor to the main shaft, ensuring high-speed rotor rotation required for impact crushing of medium to hard stones. With a standard diameter of 30 cm and a capacity for 5–7 belts, it is well suited for sand and aggregate production lines in riverbed and mountain mines, as well as in cement industry applications.

Manufactured from high-quality forged steel and fitted with an advanced taper bushing, this pulley offers excellent resistance to wear, corrosion, and looseness. Its service life can reach 12–18 months under severe operating conditions. Key advantages include reduced friction, ease of maintenance, and compatibility with various Kubit crusher models, significantly lowering maintenance costs. Novincsm supplies this product with warranty and after-sales support.
