Electric motors account for some of the highest numbers of reliability incident reports involving rotating equipment and machinery. Widi bearings are applied on electric motors from a few hundred kilowatts to tens of megawatts.

Bearings

• Deep groove ball bearings
• Hybrid bearings
• Cylindrical roller bearings
• Angular contact ball bearings
• CARB toroidal roller bearings

Applications

General purpose motors

High-volume, generally off-the-shelf catalogue motors are small to medium-sized units, typically 1 to 500 kW. Adding to our complete offering of seals, standard bearings and greases, our electrically insulated bearings protect your motors against stray currents and help improve motor performance, maintain machine profitability and reduce costs over time.

Application-specific motors

As their name implies, application-specific motors are designed to meet very specific application requirements and operating conditions. Quite often, they are catalogue motors that have been modified to meet specific requirements.

• ELECTRIC TRACTION MOTORS
• TRACTION MOTORS FOR RAILWAYS
• TRACTION MOTORS FOR ELEVATORS
• VERY LARGE MOTORS

Controlled motors

The growing demand for precise and variable processes plus the increased focus on realizing potential energy savings require motors that can be accurately controlled. Widi offers a range of motor control feedback devices that – depending on the application requirements – either can be integrated in the bearing or mounted to the shaft.

Belt drive motors

Belt drive motors are a less costly alternative to direct drive. They can absorb significant amounts of shock and vibration, and, eliminating the need of gearboxes, speed and torque shifts are made possible by adjusting the size of the pulleys in the belt drive system.
