Product description
Heavy-duty lifting requires specialized components, and this 6-inch hole plunger is engineered to provide the power and stability needed for larger Rotary systems. As a replacement for the JG446, this plunger is a core element of the hydraulic cylinder assembly, responsible for supporting the lift carriage during operation. SVI International uses high-grade materials to ensure this part can withstand significant axial loads without compromising on surface smoothness. A damaged plunger can cause uneven lifting or even catastrophic seal failure, so replacing it at the first sign of wear is essential for maintaining shop safety. The 6-inch configuration is designed for high-capacity applications where additional stability and fluid displacement are required. This part is a direct-fit solution that minimizes downtime during lift overhauls.
Product highlights
- High Capacity: Designed for heavy-duty Rotary lift systems requiring 6-inch plunger assemblies.
- Surface Integrity: Polished finish reduces friction and extends the life of hydraulic packings.
- Structural Strength: Thick-walled steel construction provides maximum resistance to pressure.
- Reliable Seal Interface: Ensures a tight seal to prevent hydraulic fluid bypass and drift.
