Gisholt 2U Masterline Balancer | Size 500 | 5.5" Shaft Capacity | Ideal for Digital Upgrade

Gisholt 2U Masterline Horizontal Balancer (Size 500)

Type: 2U | Size: 500 | Condition: Mechanical Base Only / Retrofit Candidate

The Gold Standard for Rebuilds

The Gisholt Masterline series is legendary for its massive, vibration-dampening cast-iron bed. While the legacy analog electronics may no longer hold tight production tolerances, the mechanical integrity of this frame remains superior to many modern lightweight alternatives. It is the preferred platform for digital retrofits from leading providers like BalanStar, ABRO, or Precibalance.

Unit as-is powers on and functions as intended. The ability for it to hold tight tolerances over heavy usage is in question due to the age of the machine.

Technical Specifications

• Weight Capacity: 25 lbs (min) to 500 lbs (max).
• Swing Capacity: Massive 68" overall diameter.
• Distance Between Centers: Up to 60" between coupling and opposite bearing.
• Shaft Diameter: Capacity up to 5.5" at bearing surfaces.
• Balancing Speed: Rated for approximately 300 RPM.
• Footprint: Approx. 120" L x 48" W.
• Net Weight: Approximately 5,500 lbs of high-density cast iron.

Why Retrofit This Frame?

• Cost Efficiency: Retrofitting this frame typically saves 40–70% compared to purchasing a new 500-lb capacity machine.
• Enhanced Precision: Modern digital instrumentation can "read through" mechanical age, often resulting in better-than-factory accuracy once the legacy vacuum-tube or analog systems are removed.
• Industrial Durability: Modern machines of this weight class are extremely expensive to ship and manufacture; this Gisholt offers a 2.5-ton foundation that eliminates floor-induced vibration.

Dealer Note

"This Gisholt 2U represents the best 'project' value in the balancing industry. The mechanical work supports and bed are in solid condition, making it ready for a modern touchscreen control and hard-bearing sensor package. Once upgraded, this machine will easily compete with systems costing $35,000 or more."
