Schunk 224412 Hydraulic Chuck Sleeve 0.75 in Id 1.25 in Od

Product Description

The SCHUNK 224412 is a hydraulic chuck sleeve designed for use in hydraulic toolholding systems on CNC machining centers and milling machines. It features a 0.75 inch bore and a 1.25 inch outside diameter, with a length under head of 2.3819 inches. Constructed from steel, this sleeve transmits clamping force from the hydraulic chuck body to the cutting tool shank. It supports coolant-through delivery, directing cutting fluid directly to the tool tip for improved chip evacuation and thermal control. Installation is performed by qualified machinists or toolroom technicians as part of a hydraulic chuck assembly.

This sleeve is suited for precision metal-cutting applications where repeatable tool runout and rigid clamping are required. Typical use cases include high-speed milling, drilling, and reaming operations in production and job shop environments. The coolant-through feature makes it well matched to deep-hole drilling and long-reach tooling setups where flood coolant alone is insufficient. It is sized for 3/4 inch shank tooling, a common diameter in both inch and metric tooling inventories.

Key Features

• 0.75 inch inside diameter accepts standard 3/4 inch tool shanks
• 1.25 inch outside diameter for fitment in compatible hydraulic chuck bodies
• Coolant-through design routes cutting fluid directly to the cutting zone
• 2.3819 inch length under head provides adequate shank engagement depth
• Steel construction for rigidity and durability under high clamping pressures
• Head diameter of 1.3976 inches (35.50 mm) for proper seating against the chuck face

Compatibility

Designed as a replacement or spare sleeve for SCHUNK hydraulic chuck bodies that accept a 1.25 inch OD sleeve with a 0.75 inch bore. Verify chuck body bore diameter and sleeve length specification against your toolholder documentation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with hydraulic toolholding systems. Ensure the machine spindle is fully stopped and the hydraulic chuck is depressurized before removing or installing any sleeve. Clean the chuck bore and sleeve OD thoroughly to remove chips, oil film, or debris that could affect runout. Consult the chuck manufacturer's documentation for torque and clamping procedures specific to the chuck body model.
