Precision Power-Transmission Sprocket

The TRITAN 50BS15H is a finished-bore steel sprocket built for 50 chain. Its 1 3/16 inch bore and integral keyway suit shaft-driven equipment where positive torque transfer matters. Fifteen teeth and a 3.006 inch pitch diameter deliver consistent engagement. Black-oxide finish protects against corrosion in industrial environments.

Included Set Screws Simplify Installation

Two set screws come in the box, allowing immediate locking to the shaft without sourcing separate hardware. The 1/4 inch wide by 1/8 inch deep keyway mates with standard keys to prevent rotational slip. Hub projection of .657 inch and 2 3/8 inch hub diameter keep the assembly compact on tight machinery layouts.

Capacity Suited to Moderate Loads

Fifteen teeth on 50 chain handle typical conveyor and drive loads within the sprocket's rated geometry. The 3.32 inch outside diameter clears adjacent components in standard guards. Applications demanding higher tooth counts, larger bore sizes or multi-strand chain will need a different sprocket.

Questions about this item

How often will the 1/4 in keyway and 1/8 in depth need inspection on this 15-tooth sprocket?

Inspect the keyway fit and set-screw torque at each scheduled shutdown; the 1/4 in width and 1/8 in depth show wear before the teeth on 50 chain drives.

What wears first when this 3.32 in OD sprocket runs continuously on 5/8 in pitch chain?

The 15 hardened teeth carry the full load, so tooth flank wear appears before the 2 3/8 in hub or the 1 in bore length.

How much heat does the black-oxide finish add during all-day operation at 1 3/16 in bore?

The finish is cosmetic; heat comes from chain tension and speed, not the coating, so monitor lubrication instead of surface temperature.
