ساحبات عكسية ثلاثية الفكوك من ساتا قياس (4") موديل (ST90634SC)

Key specs include a reversible jaw design for internal/external pulling, durable heat-treated steel construction, precision-machined threads and jaws for smooth operation, adjustable jaws to fit different bearing/gear sizes, heavy-duty capacity for professional use, an ergonomic handle for comfort, an anti-rust coating, and a compact, portable form. The spindle is phosphate-coated to resist corrosion.

To switch between internal and external pulling, detach or rotate the jaws as specified in the tool’s adjustment mechanism, then resecure them in the desired orientation. The reversible jaw design is intended to simplify configuring the tool for the target component, whether you’re pulling bearings from the outside or drawing components from the inside.

This puller is well-suited for pulling bearings, gears, pulleys, and similar components where precise alignment and controlled force are needed. The adjustable jaws accommodate different sizes, and the 3-jaw configuration helps distribute pulling force securely across irregular shapes.

The tool is designed for professional mechanical and automotive use, with corrosion resistance thanks to the spindle coating and anti-rust finish. Its heat-treated steel construction makes it capable of handling heavy-duty pulling tasks in workshops and job sites.

After use, keep the tool clean and dry. Apply a light coat of oil to moving threads to reduce wear and ensure smooth operation. Store in a dry place to preserve the anti-rust coating and prevent corrosion. Periodically inspect jaws and threads for wear and re-tighten as needed.

The 3-jaw design provides more contact points and greater grip stability on irregular parts, improving pulling security and alignment. The SATA 2-Jaw option is typically lighter and simpler, but may offer less even load distribution on larger or irregular components.

The 4-jaw version distributes pulling force across four contact points, which can offer even load distribution on challenging parts and tighter centering. The 3-jaw model provides a strong, versatile solution with excellent grip for most jobs. For an optional four-jaw alternative, see: https://fepy.com/products/sata-4-jaw-reversible-pullers

If you’re evaluating options, you might compare with the SATA Bearing Puller Set for more specialized bearing removal tasks. See: https://fepy.com/products/sata-bearing-puller-set

Common use cases include removing bearings from shafts, extracting gears from hubs, pulling pulleys from shafts, and servicing components where precise, controlled pulling is required without damaging parts. The reversible jaws make it adaptable to both internal and external pull tasks in daily workshop activities.

Yes. Always align the puller straight with the component to avoid slippage, apply steady, even force rather than sudden jerks, wear eye protection, and ensure clamps and jaws are properly secured before applying pressure. Use the internal/external configuration appropriate for the task to minimize component damage and tool wear.
