KATSU Tools 4 Inch 100mm Two Jaw Gear Bearing Puller Extractor Ultra Thin 2mm Claws Mini 2 Arm Extractor 450462
Product Overview
The KATSU Tools 4-Inch (100mm) Two-Jaw Gear and Bearing Puller (450462) is a specialized, compact mechanical extraction tool engineered for precision pulling in narrow, confined, and hard-to-reach spaces. Specifically designed for delicate components where standard puller claws are too thick to insert, this mini 2-arm extractor effortlessly removes small bearings, gears, flywheels, and belt pulleys without damaging surrounding housings.
Manufactured from high-grade drop-forged, heat-treated carbon steel, the tool features ultra-thin 1.8mm–2.0mm claws that slide into tiny gaps behind tight gears and bearings. Offering a transverse opening range of 18–50mm, an 80mm working reach, a 90mm working stroke, and a 125mm center lead screw, it provides balanced, stable extraction force for power tool maintenance, automotive repairs, and precision workshop mechanics.
Features
-
High-Grade Drop-Forged Carbon Steel: Heat-treated and tempered steel body provides maximum tensile strength and durability for tough extraction tasks.
-
Ultra-Thin 1.8–2.0mm Claw Footprint: Exceptionally slender claw tips easily slip into restricted gaps behind narrow bearings and gears.
-
2-Arm Balanced Pulling Action: Two-claw configuration ensures even force distribution to prevent tilting, binding, or shaft scoring.
-
Adjustable Clamping Depth: Multi-hole jaw positioning allows custom vertical and horizontal reach for various component sizes.
-
Extended 80mm Reach & 90mm Stroke: Deep working depth combined with a 125mm threaded center rod handles medium mechanical assemblies in confined spaces.
-
Ideal for Power Tools & Automotive Maintenance: Perfect for extracting armature bearings, alternator pulleys, motorcycle wheels, and machine gears.
