FAQ

What is Mersen grade EG313 suitable for?

EG313 is a carbon-graphite grade known for its good commutating properties and low friction. It is typically used for DC motors and generators with medium to high speeds and current densities, often in industrial applications like traction motors or heavy-duty machinery.

How do I confirm if this brush is the correct size for my motor?

This brush has a specific part number (513866-1,000) which corresponds to precise dimensions (length, width, thickness). You must measure your existing brush or consult the motor’s technical manual to ensure the dimensions match exactly for a proper fit and safe operation.

Can I replace a brush of a different grade with this EG313 brush?

It is not recommended. Different brush grades have specific electrical and mechanical properties such as resistivity, hardness, and friction coefficient. Using the wrong grade can lead to poor performance, excessive commutator wear, or even motor failure. Always replace with the manufacturer-specified grade.
