Schunk 224380 Hydraulic Chuck Sleeve 3/8 in Id 1/2 in Od

Product Description

The SCHUNK 224380 is a hydraulic chuck sleeve designed for use in hydraulic toolholding systems on CNC machining centers and milling machines. It features a 0.375-inch (9.53 mm) inside diameter and a 0.500-inch (12.70 mm) outside diameter, with a length under head of 1.7717 inches (45.00 mm). The sleeve supports coolant-through operation, allowing cutting fluid to pass directly to the tool tip for improved chip evacuation and thermal management. Constructed from steel, it delivers the wall rigidity required to maintain concentricity under high-speed cutting loads. Installation is handled by machinists or toolroom technicians as part of hydraulic chuck assembly and tool setup.

This sleeve is used in hydraulic expansion chucks where the sleeve transmits clamping pressure from the chuck body to the cutting tool shank. It is suited for high-precision applications in both production and job-shop environments. The coolant-through design makes it particularly well-matched to deep-cavity milling, drilling, and reaming operations where flood coolant at the tool tip reduces heat buildup and extends tool life. The 0.375-inch bore accommodates standard 3/8-inch shank tooling.

Key Features

• 0.375-inch (9.53 mm) inside diameter fits standard 3/8-inch tool shanks
• 0.500-inch (12.70 mm) outside diameter for hydraulic chuck body fitment
• Coolant-through design channels cutting fluid directly to the tool tip
• 1.7717-inch (45.00 mm) length under head for consistent tool projection
• Steel construction provides rigidity and resistance to deformation under clamping pressure
• Head diameter of 16.50 mm seats flush and securely in compatible chuck bodies

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck systems requiring a 3/8-inch bore and 1/2-inch outside diameter with coolant-through capability.

Installation Notes

Installation is typically performed by a machinist or toolroom technician during hydraulic chuck assembly or tool change procedures. Always release hydraulic pressure in the chuck body before removing or inserting a sleeve. Verify bore and outside diameter tolerances against the chuck manufacturer's specifications before assembly. Follow the machine tool builder's guidelines for clamping torque and coolant pressure limits.
