Built from alloy steel with a black oxide finish, this unit features a Delrin ball contact element that pivots to conform to uneven or angled workpiece surfaces. The 4-40 threaded base mounts into tapped fixture plates, providing a low-profile, reliable contact point with a rated load capacity of 1,835 pounds. With a flat ball pad surface and a contact diameter of 5\/32 inches, it delivers consistent, repeatable part location in tooling, jigs, and fixture builds.\u003c\/p\u003e\n\u003cp\u003eThis gripper assembly is suited for use in machining fixtures, assembly jigs, and inspection tooling where swivel contact is needed to accommodate slight surface irregularities. The 5\/32-inch Delrin ball swivels up to 28 degrees, allowing positive contact on non-parallel surfaces without marring the workpiece. At 3\/4 inches overall height with a 1\/16-inch standoff, this base unit integrates cleanly into compact fixture designs. Machinists, toolmakers, and fixture builders working with precision metalworking setups are the primary installers of this component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSwivel angle of 28 degrees accommodates angled or uneven workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003e1,835-pound load rating for high-clamping-force fixture applications\u003c\/li\u003e\n  \u003cli\u003eDelrin ball contact element resists marring on finished or sensitive workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eFlat ball pad surface for consistent, predictable contact geometry\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide finish for corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eNon-replaceable pad design with 4-40 thread for direct installation into tapped fixture plates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a base-type swivel action gripper assembly for use with 4-40 tapped fixture plates and tooling setups requiring a low-profile, swiveling point-of-contact element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or fixture builders using standard hand tools sized for 4-40 threaded fasteners. Thread the base into a pre-tapped 4-40 hole to the specified 5\/16-inch thread depth before applying load. Verify the mating surface is clean and free of chips or debris prior to assembly to ensure accurate seating. Do not exceed the rated load capacity of 1,835 pounds during fixture operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Rating\u003c\/strong\u003e: 1,835 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Diameter\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandoff\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwivel Angle\u003c\/strong\u003e: 28 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Delrin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Pad Surface\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReplaceable Pad\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Base\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FAIRLANE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BBU-107-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FAIRLANE","offers":[{"title":"Default Title","offer_id":67910939541810,"sku":"BBU-107-D","price":43.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52969f2f5f00af7ca316848b4b5ca1dd.jpg?v=1791201859","url":"https:\/\/voomisupply.com\/products\/fairlane-bbu-107-d-swivel-gripper-assembly-base-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
