Boeing 787 Air Shafts
Precision balancing air shafts that end up on the Boeing 787 is an art. The corrections are made in a milling machine using carbide end mills with very specific corner radii. The part is gripped on one end in an index head and is supported in a lathe steady rest to mill to precision requirements. These parts are extremely delicate and have fragile labyrinth seals that can be destroyed with a very light bump. The value of the shaft as you see here is over $10,000 USD.
Permanent Magnet Rotor
Permanent magnet rotor sits in our custom 2500 pound balancer.
16,000 pound Impeller for Providence Rhode Island Hurricane Barrier Pump Station
A large 16,000 pound impeller for Providence Rhode Island Hurricane Barrier Pump Station is loaded into the 30,000 pound soft bearing balancing machine. This machine is particularly suited for precision balancing large rotors. It can measure unbalance at speeds as low as 80 rpm and as high as 5,000 rpm. The machine supports sit on a bed custom built at HI-TEK Balancing and the stations are Gisholt with our own self aligning bearing blocks designed in house. The balancing electronics are IRD 236. The combined weight of the arbor and rotor is 21,000 pounds.

Paper Machine Rolls
Paper machine rolls are balanced and material is removed or added by drilling to remove, or slugs are added deeper into the hollow roll shell to add weight.
Pneumatic Belt Grinder
A 75 kw natural gas power turbine rotor is two plane balanced. Weight removal is by pneumatic belt grinder. The grinder is mounted to the tool post grinder to control the grinding and keep within the specified material removal zone.
Large Freshwater Pump Impeller
A large freshwater pump impeller for a municipality pumping water from a reservoir to the treatment plant. The arbor was made and fitted in-house and the rotor was balanced to API balancing standards.
22000 pound Overhead Bridge Crane
Our facility is equipped with a 22000 pound overhead bridge crane to allow for unloading large and heavy parts in a safe manner. Large flat bed trucks can be backed under the 14 foot hook height 10 ton crane.
400 HP Industrial Fan
A 400 HP industrial fan is completely rebuilt in our shop. A new shaft was machined, the spherical roller bearings were replaced and the bearing clearances were set. The blower wheel buckets were flame-spray hard-coated to prevent further wear. The fan wheel was balanced and the housing was cleaned and painted. The fan has been in service for 4 years without any further attention.
11000 pound Fluid Friction Dynamometer Rotor
11000 pound fluid friction dynamometer rotor resting in our soft bearing high speed balancer. The rotor will be balanced at 1500 rpm. Soft bearing balancers are particularly suited for high precision balancing as they do not have structural resonance problems. This soft bearing machine can easily balance large rotors below ISO g1.0.
