Sandvik Coromant 5757140 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 5757140 is a hydraulic chuck sleeve designed for use with hydraulic tool-holding systems in CNC machining and precision turning applications. It provides a precision-fit interface between the hydraulic chuck body and the cutting tool shank, transmitting clamping force evenly for secure, vibration-resistant tool retention. The sleeve features through-coolant capability, allowing pressurized coolant to pass directly to the cutting zone for improved chip evacuation and tool life. With a 1-inch inside diameter, a 1.5-inch outside diameter, and a head diameter of 1.7362 inches, this steel sleeve is built for demanding metalworking environments. Machinists and CNC setup technicians are the primary installers.

This sleeve is suited for precision machining operations in both production and job-shop settings where hydraulic chucks are used to hold straight-shank cutting tools. The 3.937-inch length under head makes it compatible with deeper chuck bodies requiring extended reach without sacrificing rigidity. Through-coolant support at up to 20 psi makes it appropriate for high-speed or deep-pocket milling and boring operations where chip management is critical. It is packaged individually and is intended as a direct-fit component within compatible hydraulic chuck assemblies.

Key Features

• Through-coolant capable, supporting pressurized coolant delivery directly to the cutting zone
• 1-inch inside diameter and 1.5-inch outside diameter for precise tool shank engagement
• Head diameter of 1.7362 inches for proper seating against the chuck body
• 3.937-inch length under head accommodates deeper chuck configurations
• Steel construction for durability under high clamping pressures and machining loads
• Coolant pressure rating of 20 psi

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck assemblies requiring a 1-inch bore sleeve with through-coolant functionality. Refer to your chuck manufacturer documentation to confirm sleeve geometry before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Before servicing the chuck assembly, ensure the machine spindle is fully stopped, the control is in an E-stop or locked-out state, and coolant supply is depressurized. Sleeves should be inserted without force; if resistance is felt, inspect the bore and sleeve for contamination or burrs before proceeding. Do not exceed the rated coolant pressure for the chuck assembly.
