Accessories & Spare Parts

EI-300 Balancing Machine has a wide range of optional accessories and spares to increase performace and realiability.

Negative Load Support

Negative Load Support SBS300

It’s an accessory for EI- 300 Balancing Machine required to secure rotors with high levels of vibration, like crankshafts.

Each support includes bearings and has adjustable height.

Transmission Belt

Power transmission V-belt made of EPDM (ethylene propylene diene monomer) rubber for resistance to weathering, oils, water, and some solvents. Its cords are bonded to the body are strongly bonded to the body of the belt for equal load distribution and reducing bending stress without deterioration of the cord. 

Axial Supports


Designed to limit the axial rotor’s displacement on the EI-300 balancing machine. It has 2 axes to adjust up to 1 meter shaft’s length from the supports. They include the mounting base to the balancing pedestal, an axial and radial arm and a rolling element at the tip.

Pulleys Set

SBS300 Pulley Set

Set of 3 bearing pulleys and 1 driver pulley for EI-300 flat belt.
