Model 11.1 Horizontal, Universal Balancer

Product catalog summary

Overview: The Model 11.1 Horizontal, Universal Balancer is a versatile two-plane balancing machine designed for high-precision applications such as armatures, spindles, shafts, and more. It utilizes hard-bearing technology and force-measuring transducers for accurate unbalance measurement.

Key Features:

Rugged piezo-electric transducers that are resistant to temperature and humidity changes and are sealed against dust and dirt.
Fully traversable work supports along parallel support rails.
Options for V-block, roller bearing, or half-shell supports.
Adjustable end-thrust assemblies with precision ball bearings for axial load in belt-drive systems.
RPM detection via photocell or phase-coil.
Optional safety guard compliant with OSHA and CE standards.
Available in table mounting or precision-machined steel floor stand.
Custom hardware and software options.
Various electronic measuring instruments available upon request.
All-metric design.
