QI C HANGZHOU OCEAN INDUSTRY CO., LTD. BTLW/WH weld-on hubs This type of taper bore weld-on bubs adopt the Europe standards. Taper Bore Weld-on Hubs are made of steel; drilled, tapped and taper bored to receive standard taper bushes. The extended flange provides a convenient means of welding hubs into fan rotors, steel pulleys, plate sprockets, impellers, agitators and many other devices which must be firmly fastened. These are entirely suitable for severe operating conditions. Tightening the screws will contract the bores of the bush thereby locking it to the shaft with the equivalent of a press...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Adapters for Taper Bushings are recommended for usage where it is more convenient to use a straight bore rather than to drill and tap to accommodate the bushings. The adapter is a taper bored sleeve of grey cast iron which fits into the straight bore of a hub. The bushing simply fits inside the adapter which is tapped for the bushing screws. When tightening the locking screws, the adapter is expanded against the hub bore, pressing the bushing tightly upon the shaft. TAPER ADAPTERS

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Taper Bolt-On Hub is one type of bolt-on hubs that are specially designed for bushes. It’s characteristics are simple structures with easy on and easy off capabilities and the ability to use on both sides simultaneously. It applies to vane wheels, fans and other parts which must be fixed closely with shafts. Taper Bolt-On Hubs are made of high standard grey cast iron GG25 which have enough intensity. The surface is phosphate, attractive and anti-rust. They are a standardized product and highly interchangeable which will lower stock costs. TAPER BOLT - on...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. QTL Taper Bushings are made of GGG40 ductile iron and the surface is phosphate. They are fixed with UNC bolts (12.9 grade) and packed individually. QTL Taper Bushing and JA-E with inner bore and keyways in standard measurements can be sold off the shelf with immediate delivery. F-S are produced against orders with prompt delivery.
