Accurate balancing is essential to the Operation, Maintenance, and Repair of rotating equipment.

Whether you are dealing with a turbine in a power plant, a fan in a chemical facility, a rotor or an armature from an electric motor, or a roll in a paper mill, your rotating equipment needs to be balanced as precisely as possible.

Sandrin Services Inc. has recently acquired two Balancing Machines. Our "B5" has a 1 - 500 pound capacity with a 36" rotor diameter and a 47.25" maximum journal separation. Our larger unit, the "B150" has a capacity up to 15,000 pounds with a 115" rotor diameter.

By extending the outer support of the B150 to the length of your rotor, we have the ability to increase the journal separation to accommodate all of your balancing requirements.

At Sandrin Services Inc., We Balance Innovation with Technology.
