The insert is standard on eligible hollow quill-input configurations across Cyclo, Helical BuddyBox and Bevel BuddyBox 4 gearboxes, with no change to model number, price or lead time.\n\n## How the Quill Bushing Works on NEMA Inputs\n\nSmall movements between the motor shaft and quill bore can cause fretting corrosion over time, making the motor hard to separate from the gearbox and lengthening maintenance downtime. The Quill Bushing separates the metal surfaces at the connection so the motor can be removed more easily when service is needed. It also removes the need to apply anti-seize paste to the motor shaft during assembly.\n\nA patent-pending retaining lever locks the insert in the quill shaft so it cannot back out during operation. \"Fretting corrosion is a common maintenance problem on quill-input gearboxes, especially in high-cycle conveyor applications,\" the company said in the announcement.\n\nInternal R&D laboratory testing found no corrosion, and field test units have operated for three years at major parcel carrier facilities at about 400 starts per day, remaining in service with no reported issues. The Quill Bushing covers Cyclo sizes 606 through 616 and NEMA motor frames 56C through 250TC. The original all-steel keyed hollow bore quill remains available on request, and spare inserts can be ordered separately for equipped units.\n\n## Sumitomo's Broader Gearbox Lineup\n\nAccording to akta.pro [company records](https://akta.pro/company-data), Sumitomo Drive Technologies has launched the Fine Cyclo B-Series precision gearboxes, zero-backlash units covering 120–231mm outer diameters, 417–4,000 Nm acceleration torques and up to 8,000 Nm peak torque for automation, robotics and machine tool applications. The same records list the Smartris Compact Plus servo drive for AGV and AMR applications, which adds EtherCAT and PROFINET interfaces plus SIL3-certified STO and SBC safety functions.\n\nThe company also launched the NEO Essential Series at SPS Nuremberg, four gearmotor lines (Prest NEO, Altax NEO, Hyponic NEO and Planetra NEO) starting at €172. Sumitomo Drive Technologies traces its Cyclo technology origins to 1925, according to the same records.\n\n## Where to Get Configuration Details\n\nSumitomo directs customers to its [customer service contact](https://emeia.sumitomodrive.com/en-de) for configuration details and spare parts for the Quill Bushing.\n","publisher":{"name":"News for Agent","url":"https://newsforagent.com"}}
