Kennametal 1093526 Hydraulic Chuck Sleeve 16mm Id

Product Description

The KENNAMETAL 1093526 is a hydraulic chuck sleeve designed to adapt tooling within hydraulic chuck systems used in precision CNC machining operations. It features a 16 mm (0.6299 inch) inside diameter, a 19.05 mm (0.75 inch) outside diameter, and a head diameter of 24.99 mm (0.9840 inch). The length under head measures 1.969 inches (50.01 mm). Constructed from steel, this sleeve supports through-coolant delivery at up to 1500 psi, making it suitable for high-speed drilling, reaming, and boring applications where coolant management at the cutting zone is critical. Installation is performed by machinists and tooling technicians in shop environments.

This sleeve is used in hydraulic chucking systems on CNC machining centers, turning centers, and multi-axis machines where precise tool holding and coolant-through capability are required. It is a direct replacement or spare component for hydraulic chuck assemblies requiring a 16 mm bore sleeve. Typical applications include high-tolerance hole-making and finishing operations in aerospace, automotive, and general metalworking industries.

Key Features

• 16 mm inside diameter for accurate tool shank engagement
• Through-coolant capability rated to 1500 psi for effective cutting zone cooling
• Steel construction for durability under high clamping pressure
• 19.05 mm (0.75 inch) outside diameter for standard hydraulic chuck body fitment
• 1.969 inch length under head for consistent projection and tool positioning
• Head diameter of 24.99 mm provides positive seating and axial location

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck systems requiring a 16 mm bore, 19.05 mm outside diameter sleeve with through-coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Before handling, ensure the machine spindle is powered down and the hydraulic chuck pressure is fully relieved. Verify bore and outside diameter tolerances match the chuck body before seating the sleeve. Follow the chuck manufacturer's torque and clamping procedure specifications during reassembly.
