Tsubaki 6020SB Plain Bore Roller Chain Coupling","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe U.S. TSUBAKI 6020SB is a plain bore roller chain coupling designed to connect two shafts in power transmission applications. It accepts a 1-inch bore diameter and features a coupling outer diameter of 5.04 inches, making it suitable for moderate-torque drive systems. The coupling uses a standard roller chain design, allowing the chain to flex slightly and accommodate minor shaft misalignment during operation. Licensed technicians and mechanical contractors typically install this component in industrial and commercial machinery settings where shaft coupling is required.\u003c\/p\u003e\u003cp\u003eThis coupling is used in a range of power transmission setups including conveyor systems, pumping equipment, fans, and general industrial machinery. The plain bore configuration means the installer machines or specifies the keyway and set screw arrangement on-site to suit the specific shaft. It is appropriate for both new installations and replacement of worn or failed couplings in existing drive trains.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePlain bore design allows field-machined keyways and set screws to match shaft specifications\u003c\/li\u003e\n\u003cli\u003e1-inch bore diameter for compatibility with standard shaft sizes\u003c\/li\u003e\n\u003cli\u003e5.04-inch coupling outer diameter suitable for moderate-torque applications\u003c\/li\u003e\n\u003cli\u003eRoller chain coupling style provides minor misalignment tolerance between connected shafts\u003c\/li\u003e\n\u003cli\u003eCompact package dimensions of 6 x 6 x 4.5 inches for straightforward handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation plain bore roller chain coupling for standard power transmission drive systems requiring a 1-inch bore shaft connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical technician. Disconnect and lock out all power sources before removing the existing coupling or fitting the new one. The plain bore must be finish-machined to the required keyway and set screw pattern before mounting on the drive and driven shafts. Verify shaft alignment after installation to minimize coupling wear and bearing load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Plain Bore Roller Chain Coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Outer Diameter\u003c\/strong\u003e: 5.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 x 6 x 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: U.S. TSUBAKI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6020SB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"U.S. TSUBAKI","offers":[{"title":"Default Title","offer_id":67911807762738,"sku":"6020SB","price":102.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0fc3cd8279bace4a8311d33237a980e.jpg?v=1791220028","url":"https:\/\/voomisupply.com\/products\/u-s-tsubaki-6020sb-plain-bore-roller-chain-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
