Sprocket for 50 Chain

This finished-bore sprocket fits single-strand 50 chain and carries 14 teeth on a 1 1/8 in bore with keyway. It is built from steel with a black-oxide finish for corrosion resistance. The component suits power-transmission builds that need a fixed-bore driver or driven element.

Build integration

The one-sided hub measures 2 1/8 in diameter and projects .657 in through the bore, leaving the opposite face clear for flush mounting. Two set screws lock onto the keyed shaft, eliminating the need for a separate locking collar. The 1 in length through bore keeps the assembly compact inside existing guards.

Capacity and headroom

Pitch diameter of 2.803 in and outside diameter of 3.11 in define the speed ratio and chain wrap this sprocket can deliver. The 1/4 in wide by 1/8 in deep keyway handles standard shaft keys for the rated bore size. Builds requiring more teeth, a larger bore or multi-strand chain will need a different sprocket.

Questions about this item

At what chain speed does the 3.11 in outside diameter become the limiting factor under sustained use?

The 3.11 in outside diameter and 2.803 in pitch diameter define the sprocket geometry; chain speed limits depend on the full drive design and lubrication.

How much heat does the steel body with black oxide finish generate when running all day?

Heat generation depends on load, speed, lubrication and alignment; the steel construction and black oxide finish are standard for power transmission sprockets.

What shaft diameter and key size must I already have to fit the 1 1/8 in bore with 1/4 in keyway width?

You need a 1 1/8 in diameter shaft with a standard 1/4 in wide by 1/8 in deep keyway to match the sprocket bore and included set screws.
