Horizontal Balancing Machines

Hofmann horizontal balancing machines provide accurate readings, time after time. Their sturdy design combines the precision of piezoelectric transducers in a reliable hard-bearing support system on a solid steel base. Standard designs include adjustable supports and changeable bearings, enabling different rotors types to be used on each machine size. Custom and special designs, such as side spindles for overhung rotors, are engineered to individual rotor specifications.

Hofmann horizontal machines meet a wide range of balancing requirements. Features include the following:

Standard machines available for a wide range of rotor sizes (from a few grams to 40,000 kg), special machines for larger rotors
Adjustable supports allow different size rotors for each size machine
Drive system options to meet rotor type requirements:

Belt, end, or combination drive systems
Under/over belt configuration
Larger ac and dc drives/motors
Gear transmissions
Auto-indexing of rotors
Rotor locking system for rotor correction
Remote angle

Optional pneumatics for clamping and adjustments
Roller bearings for wide range of journal diameters
V-bearings or half shells for rotors with their own bearings
Machine bed extensions or separate short beds
Proving rotors to Hofmann, ISO, or SAE ARP standards for machine calibration
Safety enclosures to meet OSHA and other specific safety standards
Special tooling for balancing complex and non-standard rotors
Integrated correction systems, like drilling, milling, and weight addition
Semi-automatic and fully automatic operations
Numerous standard and customer specific software
Custom colors
