The split bushing configuration allows technicians to clamp the indicator firmly in place without marring the instrument housing. With an inside diameter of 0.375 inches and an outside diameter of 0.5 inches, this bushing provides a snug, repeatable fit that maintains indicator alignment during measurement tasks. It is a small but critical accessory used in machine shops, production environments, and field service settings where accurate runout, deflection, or surface variation readings are required.\u003c\/p\u003e\u003cp\u003eThis split bushing is intended for use with 80 series dial indicators. It fits standard indicator holding fixtures, magnetic bases, and surface gauge arms that accept a 0.5-inch OD bushing. Machinists, quality control technicians, and precision measurement professionals will find it suited for both bench and in-machine applications where a secure indicator mount is essential for repeatable readings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSplit design allows tool-free or minimal-hardware clamping of the dial indicator stem\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.375 inches fits 80 series STARRETT dial indicator stems\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.5 inches compatible with standard indicator holders and fixtures\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.5 pounds, adding negligible mass to the measurement setup\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for targeted replacement or addition to existing setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with STARRETT 80 series dial indicators as stated by the manufacturer.

Ensure the indicator stem seats fully within the bushing bore before tightening the clamping mechanism on the holder. Do not overtighten the split clamp, as excessive force can distort the bushing bore and affect indicator alignment. Verify indicator freedom of movement along the spindle axis after mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Split Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 80 Dial Indicators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540431634738,"sku":"50154","price":22.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffbffbcac853a6718183d3b2ee4cbd97.jpg?v=1785854953","url":"https:\/\/voomisupply.com\/products\/starrett-50154-drop-indicator-split-bushing-80-dial-indicators","provider":"Voomi Supply","version":"1.0","type":"link"}
