Sandvik Coromant 5759523 Hydraulic Chuck Sleeve C4

Product Description

The SANDVIK COROMANT 5759523 is a hydraulic chuck sleeve machined from steel, designed to interface between a hydraulic chuck body and a cutting tool shank in modular tooling systems. The sleeve features a C4 inside modular connection, making it compatible with C4-series modular tool assemblies used in CNC turning, milling, and boring applications. With an outside diameter of 85 millimeters and an overall footprint of approximately 5.43 inches in length, this sleeve delivers the rigid, concentric clamping geometry that precision machining demands. It weighs 4.24 pounds and is sold as a single unit.

This sleeve is suited for use in production machining environments where hydraulic chuck systems are employed for high-precision tool holding. Typical applications include CNC machining centers and turning centers running tight-tolerance work where runout control and vibration damping are critical. The C4 modular connection integrates directly with SANDVIK COROMANT Capto and compatible modular quick-change tooling interfaces. Machinists and tooling technicians install this sleeve as part of a complete hydraulic chuck assembly during tool changes or when rebuilding existing chuck bodies.

Key Features

• Steel construction provides durability and dimensional stability under high clamping forces
• C4 inside modular connection for integration with C4-series modular tooling systems
• 85 millimeter outside diameter for use in corresponding hydraulic chuck bodies
• Single-piece sleeve design simplifies installation and replacement
• Precision-machined geometry supports accurate tool runout performance in CNC applications

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck assemblies requiring a C4 inside modular connection with an 85 millimeter outside diameter.

Installation Notes

Installation should be performed by a qualified tooling technician or machinist familiar with hydraulic chuck systems. Ensure the chuck body and spindle are fully de-energized and the machine is in a safe, locked-out state before disassembling any tooling components. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when seating or removing modular sleeves. Do not force the sleeve into the chuck body; verify that mating surfaces are clean and free of debris before assembly.
