Crank bearings support rotational shaft movement within reciprocating and rotary tool assemblies, reducing friction and maintaining alignment under load. This part is sourced from DEWALT's parts and accessories line, making it a direct fit for applicable tool models requiring this bearing. Installation is typically performed by power tool technicians or experienced service professionals performing mechanical rebuilds or preventive maintenance.\u003c\/p\u003e\u003cp\u003eThis crank bearing is suited for use in DEWALT power tools that rely on a crankshaft-driven mechanism. Typical applications include reciprocating saws, rotary hammers, and similar tools where the crank assembly converts rotational motor output into linear or oscillating motion. Replacement is indicated when worn bearings produce abnormal noise, vibration, or reduced tool performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM DEWALT replacement crank bearing for power tool service\u003c\/li\u003e\n\u003cli\u003eSupports rotational shaft alignment under mechanical load\u003c\/li\u003e\n\u003cli\u003eReduces friction at the crank assembly interface\u003c\/li\u003e\n\u003cli\u003eDirect replacement for worn or failed original bearing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement crank bearing for applicable DEWALT power tools.

Disconnect and isolate the tool from any power source before beginning service. Use appropriate bearing press or installation tools to seat the bearing without applying force to the bearing race in a way that could damage internal components. Refer to the tool's service manual for disassembly sequence and reassembly torque guidance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Crank Bearing\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEWALT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 108121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51161584337202,"sku":"108121","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306256521.jpg?v=1778876902","url":"https:\/\/voomisupply.com\/products\/dewalt-108121-crank-bearing-1","provider":"Voomi Supply","version":"1.0","type":"link"}
