The electric motor is a device that can be mounted on the concrete base or metal base. For large electric motor, the most suitable is the one with concrete bases, but the small electric motor can make use of metal bases.
Both the metal base and the concrete is possible that there is a sliding system. Typically, this system makes use applications where the drive is done by pulleys and belts.
Usually more flexible, it is allowed mounts and dismounts faster to the electric motor, but is allowed to be made adjustments to belt tension. Another important factor is the position of the screws that hold the electric motor sh-n-350 locking the base and they should be arranged opposite and diagonal way. The nearest rail should be placed closer to the drive pulley which is placed so that the positioning screw is placed between the electric motor and the driven machine.
