Accupro 1542814 Hydraulic Chuck Sleeve 1/4 in Sealed

Product Description

The ACCUPRO 1542814 is a sealed hydraulic chuck sleeve designed for use with hydraulic toolholding systems in precision machining applications. The sleeve accepts a 1/4 inch inside diameter shank and fits into a 1/2 inch outside diameter hydraulic chuck bore. Constructed from alloy steel, it provides the rigidity and wear resistance required for high-speed cutting operations. The sealed sleeve type retains hydraulic pressure within the chuck body, maintaining consistent clamping force on the tool. Through-coolant capability allows coolant to pass directly to the cutting zone, supporting longer tool life and improved chip evacuation during milling, drilling, and reaming operations.

This sleeve is suited for CNC machining centers and milling machines where hydraulic chucks are used to hold small-diameter tooling. It is a direct replacement component installed when the original sleeve shows wear, damage, or loss of clamping performance. The 45.00 mm length under head and 16.5 mm head diameter are consistent with standard hydraulic chuck sleeve geometry used in production and job-shop environments. Machinists and toolroom technicians performing chuck maintenance or tool setup are the primary installers of this component.

Key Features

• Sealed sleeve type maintains hydraulic clamping pressure for consistent tool grip
• Through-coolant design directs fluid to the cutting edge for thermal management and chip control
• Alloy steel construction provides durability under high rotational speeds and cutting loads
• 1/4 inch inside diameter accommodates standard small-shank cutting tools
• 45.00 mm length under head fits standard hydraulic chuck body geometry
• Replaces SKU 37313277 for direct maintenance replacement

Compatibility

Designed as a direct replacement component for hydraulic chuck bodies accepting a 1/2 inch outside diameter sealed sleeve with a 1/4 inch bore. Replaces SKU 37313277.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with hydraulic chuck service procedures. The machine spindle must be stopped and all motion fully arrested before servicing the chuck or removing any sleeve components. Hydraulic pressure within the chuck body should be fully released prior to sleeve removal to prevent injury or component damage. Follow the chuck manufacturer's service documentation for proper sleeve seating and pressure restoration procedures.
