Horizontal Balancing Machines

Hofmann horizontal balancing machines provide accurate readings, time after time. Sturdy design combines the precision of piezoelectric transducers in a reliable, hard-bearing support system on a solid-steel base.

Hofmann horizontal balancing machines meet a wide range of requirements.

Standard designs include adjustable supports and changeable bearings, enabling your to run different rotors types on the same balancing machine. We engineer custom and special designs, such as whip sensors for flexible rotors and side spindles for overhung rotors, to individual rotor specifications.

Balancer Features

• Standard balancing machines for rotor sizes from a few grams to 40,000 kg, special balancing machines for larger rotors up to 90,000 kg
• Adjustable supports allow different size rotors for each size balancing 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
• 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
• Balancing 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
• Various electronic measuring instruments available
• Custom colors
