Conveyor Shafts
Conveyor coupling shafts are used to join individual lengths of conveyor screws and allow for rotation within the hanger bearing. Steel couplings are normally furnished, however couplings with hardened bearing surfaces may be furnished where highly abrasive materials are being conveyed. Jig drilling allows for ease of installation.

Tsubaki® DS80A14 Type A Double Single Roller Chain Sprocket, 1 in Dia Bore, 4.98 in OD, 80 Chain, 14 Teeth, 1 in Pitch, Carbon Steel
This type of sprocket is commonly used in applications where two or more items are powered by a common drive shaft. The space between the sprocket plates is wider than a multi-strand sprocket and allows two separate strands of chain to engage without contacting each other. With this type of sprocket, one strand of chain may exit in a different direction than the other. For example, one strand exiting towards the ceiling and the other running parallel to the floor.
PTI 10B-31B Single Strand Hub Type B Roller Chain Sprocket, 20 mm Dia Bore, 163.9 mm OD, #10B-1 Chain, 31 Teeth, 15.875 mm Pitch, C45 Steel
Hub type metric sprockets are available with a minimum plain bore (pilot bore) and some stock finished bore sizes. Any shaft size is possible with our custom bore and keyway capability. Sprockets with hubs are typically fitted to the shaft as a clearance fit. They are held in place with two set screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press fit (or shrink fit to the shaft) is usually preferred for higher speeds or heavier loads as they fit to the shaft more securely than a clearance fit sprocket. Depending on the clearance of the shaft fit, sprockets may work slightly on the shaft causing possible fretting or shaft wear. All sprockets are available with hardened teeth from stock or on request. Press fits usually require the sprocket to be heated for installation to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A set screw can be used to secure the key. The TL taper bushed sprocket will function like the press fit sprocket and is generally easier to install.
