VSK-15A — 3-jaw self-centring reversible chuck (380 mm)

A VSK-15A chuck engineered for secure, repeatable workholding in heavy-duty turning and versatile internal/external clamping applications.

• Self-centring 3-jaw operation
• Reversible function for inside/outside clamping
• 380 mm nominal diameter
• Stable mass, 64.7 kg for reduced vibration

Reliable heavy-duty clamping for machining accuracy

The self-centring three-jaw layout provides rapid, repeatable clamping that reduces setup time and helps maintain concentricity across serial workpieces. With a nominal 380 mm diameter, the chuck suits larger components while the high mass contributes to stability during cutting, lowering the risk of chatter. The result is consistent part quality and fewer reworks thanks to precise axial alignment and repeatability.

Flexible mounting and internal/external clamping capability

A reversible jaw design allows safe transition between external gripping and internal gripping operations without changing major fixtures, supporting a wider range of turning tasks. Mounting is provided via a three-point thread pattern (3xM16) that simplifies integration with standard lathe mounting plates and fixtures. The chuck’s 156.5 mm height and substantial 64.7 kg weight contribute to a low centre of gravity and improved holding force translation from spindle to workpiece.

Durable construction and easy identification for procurement

Built for workshop longevity, the clamping unit combines a compact profile with a robust mass to withstand continuous use in industrial environments. Minimal moving-part complexity reduces routine maintenance needs, while the clear product identifiers aid ordering and inventory: SKU VSK-15A and GTIN 4061905091612. As a component designed for reliable, long-term operation, the chuck supports higher throughput and stable process capability when paired with correct mounting and machining parameters.

FAQ

What is the nominal diameter of the chuck?
The chuck has a nominal gripping diameter of 380 mm, suitable for larger turning components.

Can the chuck be used for both external and internal clamping?
Yes, the reversible jaw arrangement enables both external gripping and internal clamping without major fixture changes.

How is the chuck mounted to the spindle or backplate?
Mounting is provided via three M16 threaded fixings (3xM16) to integrate with common lathe backplates and mounting interfaces.

What does the chuck’s mass mean for machining performance?
At 64.7 kg, the elevated mass improves stability and vibration damping during cutting, which supports higher surface quality and process stability.

Which product identifiers should be used when ordering?
Refer to SKU VSK-15A and GTIN 4061905091612 for procurement and stock management.
