103 Chain Conveyor End Drive Unit
The 103 chain conveyor end drive unit pairs the 103 chain family with the 105 conveyor series. Fully enclosed, semi-enclosed and stainless steel construction options are selected to suit the assembly.

Identify the enclosure version and drive side. Matching the 103/105 family pair does not settle shaft geometry or the motor connection.
Engage the 103 Chain at the Conveyor End
The end drive locates the sprocket and shaft where the carrying chain turns toward the return. Its side plates and bearing supports maintain that position relative to the 105 beam.
Enclosure style changes the surrounding assembly. Select the fully enclosed, semi-enclosed or stainless steel version with the actual installation in mind, then compare the shaft projection and drive interface. The family pairing is the starting point for this match.

Dimensions & Fit
Show the chain reference, 105 beam section and required shaft side. Include the existing motor/reducer interface or a dimensioned shaft-end sketch.
Check the carrying level at the entry to the unit and the clearance on the return. Allow access to the bearing support and drive-side fasteners.
Carry the Chain From the Loaded Run to the Return
The driven end engages the chain as products approach discharge. The product should pass to the next support before its base loses the required carrying contact.
Check the receiving conveyor height and gap separately from the chain wrap. A drive unit that fits the beam still needs the product handoff assessed at the discharge.

Discuss a 103 End Drive
Send the 103 chain reference, enclosure version and shaft-side details. Include the 105 beam section, load, speed and quantity.
