Stepped Bushing Body with Threaded Flange Bushing and Internal Keyway Slot

Shaft coupling interfaces, gear hub connections, and conveyor drive shaft installations use a threaded flange bushing with internal keyway slot where the keyway width tolerance and thread-to-keyway angular position together determine whether the key engages the shaft groove without rocking or backlash. Ningbo Bhin Precise Machinery (established 2009, Ningbo, Zhejiang) machines this aluminium stepped bushing body with threaded flange and internal keyway slot using CNC turning and milling, with thread specification, keyway width, and keyway angular position controlled to your drawing callouts. IATF16949 and ISO 9001 certification at Bhin's Ningbo facility (about 4,000 m²) governs traceability for electric motor, hydropower, and pump shaft bushing applications. Anodizing is available in-house for aluminium bushing bore surface hardness. End markets span aerospace, medical equipment, and robotics. Include your drawing with thread standard, keyway dimensions, and alloy grade so our Ningbo facility can quote the job.
