Accupro 1542811 Hydraulic Chuck Sleeve 1in Id Slotted

Product Description

The ACCUPRO 1542811 is a slotted hydraulic chuck sleeve designed to reduce the bore diameter of a hydraulic chuck, allowing it to securely grip tooling with a 1 inch shank. Machined from alloy steel for strength and wear resistance, this sleeve features a 1-1/4 inch outside diameter and a 39.0 mm head diameter. The slotted design and through-coolant capability allow cutting fluid to reach the tool tip during machining operations, supporting chip evacuation and thermal control. This sleeve is a direct-fit component used by machinists and toolroom technicians on CNC milling and machining center setups.

This sleeve is suited for production and job-shop environments where hydraulic chucks are used for high-precision milling, drilling, or reaming operations. It is particularly useful when the available hydraulic chuck bore exceeds the shank diameter of the tool being run, requiring a reduction sleeve to maintain concentricity and clamping force. The through-coolant feature makes it compatible with coolant-through spindle setups. The length under head is 60.50 mm, which affects tool stick-out and should be factored into setup calculations.

Key Features

• 1 inch inside diameter accepts standard 1 inch shank tooling
• 1-1/4 inch outside diameter for use in matching hydraulic chuck bores
• Slotted sleeve type supports through-coolant delivery to the cutting edge
• 39.0 mm head diameter with 60.50 mm length under head
• Alloy steel construction for rigidity and long service life

Compatibility

Replaces SKU 37313053. Designed as a direct OEM-style replacement hydraulic chuck sleeve for hydraulic chucks with a 1-1/4 inch bore accepting 1 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the hydraulic chuck is fully released and the spindle is powered down before inserting or removing the sleeve. Clean both the sleeve OD and the chuck bore thoroughly before assembly to prevent fretting and maintain concentricity. Verify tool stick-out and runout with an indicator before returning the setup to production.
