Mitee-bite 31750 Id Expansion Clamp 1900 Lb Stainless Steel

Product Description

The MITEE-BITE 31750 is a stainless steel internal-diameter (ID) expansion clamp designed for precision bore and bushing installation applications. It expands within a bore to create a secure, repeatable hold without external clamping forces that could distort workpieces or fixtures. With a rated holding force of 1,900 pounds and a mounting screw size of 1/4-20, the 31750 suits demanding fixturing setups where reliable clamping and consistent repeatability are required. Machinists, toolmakers, and fixture builders working in production and job-shop environments are the primary users of this clamp type.

The MITEE-BITE 31750 is used in machining and workholding applications where a part or fixture must be located and held from an internal bore. It is suited for precision fixtures, tombstone setups, and modular workholding systems where repeatable positioning is critical. The expansion mechanism locks into the bore without requiring external clamp arms, keeping the work envelope clear. This clamp is appropriate for use in both manual and CNC machining environments.

Key Features

• 1,900 pound holding force for secure, high-load workholding
• Stainless steel construction resists corrosion and coolant exposure
• Expands within the bore from 0.5 inches minimum to 0.525 inches maximum expansion diameter
• 1/4-20 mounting screw for standard tooling plate and fixture compatibility
• Single mount hole design with 0.5 inch mount hole diameter for straightforward installation
• Precision bore and bushing installation capability for repeatable locating

Compatibility

Designed as an OEM-style replacement and standard fitment expansion clamp for workholding fixtures, tombstones, and modular fixturing systems that accept a 0.5 inch bore ID expansion clamp with a 1/4-20 mounting screw.

Installation Notes

Installation is performed by qualified machinists or toolmakers familiar with precision workholding practices. Ensure all machine power is off and the spindle is fully stopped before adjusting or removing the clamp. The bore or bushing receiving the clamp should be clean, deburred, and within the specified diameter range before seating the clamp. Do not exceed the rated holding force or overtorque the mounting screw, as doing so can deform the expansion element or damage the fixture bore.
