Finished Bore Sprockets

These finished bore sprockets are precision-engineered components designed for reliable, low-maintenance power transmission in chain-driven mechanical systems. This paired set offers a matched solution for applications requiring synchronized motion or dual-chain drive configurations.

Construction & Materials

Manufactured from high-strength carbon steel, each sprocket undergoes a controlled heat-treatment process of quenching and tempering, creating a hardened tooth surface (HRC 40–45) for excellent wear resistance, paired with a tough, ductile core to withstand impact loads and torsional stress. The smooth, machined finish on the bores and hubs ensures precise alignment, while the uncoated steel surface is compatible with heavy lubrication to extend service life in dusty, high-load operating environments.

Design Features

Precision Finished Bore: The pre-machined, precision-sized bore ensures a direct, slip-free press fit onto standard drive shafts, eliminating the need for additional keyways or set screws in light to medium-duty applications. This design simplifies installation and reduces assembly time.

Integrated Hub Design: The robust, one-piece hub provides increased structural rigidity, distributing axial loads evenly and preventing premature fatigue. The wide, flat flange offers a stable mounting surface and helps guide the chain for smoother operation.

Optimized Tooth Profile: The teeth are cut to exact industry standards using CNC hobbing, ensuring a precise profile that meshes smoothly with roller chains. This minimizes chain wear, reduces noise and vibration, and maintains consistent torque transfer even at moderate to high rotational speeds.

Performance & Applications

These finished bore sprockets are ideal for applications requiring straightforward installation and reliable chain-driven power transmission, such as:

Light to medium-duty industrial conveyor systems and packaging equipment

Agricultural machinery including small tractor drives and grain augers

Material handling systems and office automation equipment

HVAC systems and small industrial gearboxes

Their combination of rugged construction, precision engineering, and simplified installation makes them a dependable choice for systems where efficiency and low maintenance are critical.
