Contact SupplierThese Pneumatic shafts, Couplings, Chucks and Adapters are used in applications of winding / unwinding, materials e.g. paper, textile, plastic, aluminum, etc.
Expansion shafts:
Pneumatic expansion units can be used in almost all applications. These are avilable in various models of a diameter from 12.5 mm to 500 mm. Simple and well designed construction ensures a long service life. We also supply models with special shapes and individual clamping segments according to the customer requirements and designs.
Features:
Simple design on a modular principle
Minimal accumulation of dirt
They are removed by a high rate of rotation
In addition to shaft diameters from 12.5 mm to 500 mm
The individual clamping segments
They can be wound high weight and high torques
Security clap bearings are automatically closed at the start of rotation
Mounting of the foot or flange, the output shaft or the output shaft without
Choice bearings with interchangeable parts VT
Optional of the special equipment, such as. brakes, clutches, etc.
Ensure compatibility between the snap bearing and shaft expansion
Mechanical expansion shafts
Mechanical expansion shafts Vorwald can be supplied with individual clamping segments which can be used in all applications. Simple design allows for long service life. Mechanical expanding shafts with clamping sets, sheets and centering ledges are available for cores with internal diameters from 50 to 600 mm.
Features:
High load capacity for heavy coils
Centered clamping (therefore subject to very high speed)
High torques transmission
Easy handling
Little maintenance required
Expansion couplings
Vorwald expansion adapters are an economical alternative to expansion shaft. Expansion adapter may be used in both directions of winding and allows for secure and safe mounting of torque transmission with no-axial movement.
Features:
Fast adaptation to different diameters of tubes
Light weight adapter
Easy handling
Inner hole according to customer specifications
Notably suitable for narrow strips of material and tubes with thin walls
Different standard sizes: 70, 76, 100, 120, 150, 152 and 152.4 mm
Expansion chucks
Vorwald are suitable for unwinding without shaft for rewinding and unwinding machines. Simple design allows for long service life. There are several different types of expansion bolts with different types of clamping elements.
Features:
Transmission of high torques
Actual operating tolerance of +/- 0.1 mm
Quick clamping and clamping permission
There diameters of the pins of the expansion in the range of 50-500 mm
Absolutely concentric clamping tubes
Mechanical adapter
Vorwald adapters model series 900 with individual expansion jaws, expansion or rails are required when it is necessary to perform frequent changes because of different diameter tubes.
Features:
Transferring the highest torques
Actual operating tolerance of +/- 0.1 mm
Quick release clamping and clamping
Absolutely concentric clamping tubes
Adapters available diameters in the range 98-500 mm
