Kreatos EMG 20

A specialist low-noise bearing grease for electric motors and robotics. Built for the ball and roller bearings in actuator motors, fan motors, pump motors and precision robotic assemblies, where quiet running and long bearing life matter most. This is a bearing grease, not a gearbox or plastic-gear grease.

What it is

EMG 20 is a polyurea NLGI 2 grease built on the performance concept of a low-noise electric motor bearing grease (Mobil Polyrex EM-type technology). Its job is bearing lubrication: low oil separation keeps the grease stable in the bearing, the polyurea structure gives long high-temperature life, and the formulation is tuned for quiet ball and roller bearing operation with controlled torque. Use it where the manufacturer specifies an electric motor bearing grease or a low-noise polyurea NLGI 2 grease.

Best for

• Electric motor ball and roller bearings
• Robotics actuator and servo motor bearings (where specified)
• Fan motor and pump motor bearings
• Low-noise bearing applications
• Precision robotic bearing assemblies
• Elevated-temperature bearings needing low oil separation

What it does well

• Low bearing noise, its main strength
• Long motor bearing life at elevated temperature
• Low oil separation for stable lubrication
• Protects against rust and corrosion
• Stable polyurea grease structure
• Controlled torque in ball and roller bearings

Not the right grease for

EMG 20 is a bearing grease only. For other robot jobs, reach for the right product instead: robot or actuator gearboxes need a semi-fluid gearbox grease; plastic servo gears need a plastic-safe silencing grease; electrical contacts need ECG 37 (protection) or CCG 4 / SCG 47 (conductive); damping joints need a damping grease. Do not use EMG 20 on belts, print beds, exposed dusty rails, thermal interfaces, or rubber seals unless compatibility is confirmed.
