SATA GL90638 3-Jaw Reversible Pullers 8"

Key specs include an 8" capacity, a reversible jaw mechanism for internal or external pulling, high-tensile strength construction, precision engineering for smooth operation, a pilot point on the screw tip for centering, and a phosphate-coated finish with heat-treated components for durability.

The jaws can be oriented to grip from the inside (internal pull) or from the outside (external pull). This provides flexibility to remove components without damaging teeth, shafts, or housings.

Common applications include removing bearings, gears, pulleys, and bushings from shafts in automotive, industrial, and mechanical setups where internal or external pulling is required.

Center the pilot point on the shaft, position the jaws on the component, ensure even grip, and apply steady, perpendicular pressure with the screw. Avoid sudden jerks, check alignment frequently, and stop if there’s noticeable resistance or misalignment.

Wear eye protection and gloves, secure the workpiece and puller firmly, avoid overloading beyond the tool’s capacity, keep hands clear of moving parts, and inspect the tool for wear or damage before use.

Keep moving parts clean, lightly lubricate the screw and pivot points, check jaw alignment for wear, and store in a dry location to prevent corrosion.

The GL90638 features reversible jaws for internal/external pulling. If you need different jaw configurations or additional jaw sets, check for compatible accessories from SATA on Fepy.

The standard package typically includes the 8" 3-Jaw Reversible Puller, the adjustable jaw assembly, and a screw-operated center point. A user manual is usually included as well.

Yes. It’s designed with high-tensile-strength materials and heat-treated components to handle demanding, heavy-duty pulling tasks while maintaining precision.

Both pullers offer 8" capacity and reversible jaws for internal/external pulling. The GL90639 may differ in slight jaw geometry or handle design, but both are built for durable removal of gears, bearings, and pulleys.

The GL90637 is a smaller 6" variant vs. the 8" GL90638, offering a lower capacity and potentially different leverage. Choose GL90638 for larger components and GL90637 for tighter spaces or smaller applications. Compare details here: https://fepy.com/product/sata-gl90637-3-jaw-reversible-puller-6

GL90632 is another 8" 3-jaw reversible puller option which may have different jaw geometry, weight, or handling features. If you’re choosing between them, review jaw design, centering features, and ease of use on the product pages: https://fepy.com/product/sata-gl90632-8in-3jaw-reversible-puller
