⚙️ Applications
The VS290 Spacer Element is suitable for various industrial applications, including:
-
Pumps
-
Compressors
-
Blowers
-
Mixers
-
Conveyors
-
Fans
Its design allows for easy replacement without disturbing the hubs or connected equipment, making it ideal for maintenance and repair scenarios.
✅ Advantages
-
No Lubrication Required: Reduces maintenance needs and associated costs.
-
Torsionally Flexible: Accommodates angular, axial, and parallel misalignments.
-
Durable Material: Polyurethane construction provides superior chemical and environmental aging resistance compared to rubber-based solutions.
-
Easy Installation and Replacement: Split-in-half design allows for quick and easy replacement without the need to disturb the hubs or connected equipment.
-
Cost-Effective: The design allows for the use of a smaller-sized coupling, ultimately lowering the Total Cost of Ownership (TCO).
