Accupro 1534206 Hydraulic Chuck Sleeve 1/4 in Slotted

Product Description

The ACCUPRO 1534206 is a slotted hydraulic chuck sleeve designed to adapt smaller-shank cutting tools for use in hydraulic chuck toolholders. The sleeve features a 1/4 inch inside diameter and a 3/4 inch outside diameter, with a head diameter of 24.0 mm and a length under head of 50.50 mm. Constructed from alloy steel, it delivers the rigidity and wear resistance required for high-speed machining operations. The through-coolant design allows cutting fluid to pass directly to the tool tip, improving chip evacuation and extending tool life. This sleeve is installed by machinists and CNC setup technicians working with hydraulic chuck systems.

This sleeve is suited for machining centers, CNC milling operations, and similar metal-cutting applications where a hydraulic chuck requires a reducer sleeve to hold smaller-diameter tooling. The slotted configuration accommodates tools with drive flats or coolant ports and supports consistent clamping pressure across the sleeve bore. It is a single-piece replacement component sold individually, making it practical for spot replacement in production environments where a single chuck position requires a different bore size.

Key Features

• 1/4 inch inside diameter fits common small-shank end mills and drills
• 3/4 inch outside diameter for use in standard hydraulic chuck toolholders
• Slotted sleeve type accommodates tools with drive features or coolant passages
• Through-coolant compatible for direct flood or high-pressure coolant delivery to the cutting edge
• Alloy steel construction provides strength and resistance to deformation under clamping load
• 50.50 mm length under head suits standard reach requirements in hydraulic chuck assemblies

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck toolholders accepting a 3/4 inch outside diameter reducer sleeve. Per supplier data, this part replaces SKU 37313111.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Before inserting or removing a chuck sleeve, confirm the spindle is fully stopped and the machine is in a safe, locked-out state per shop lockout/tagout procedures. Clean the sleeve bore and chuck bore thoroughly before assembly to prevent contamination-related runout. Do not force the sleeve into the chuck body; the sleeve should seat smoothly under hand pressure before the hydraulic clamping mechanism is engaged.
