Finished Bore Industrial Roller Chain Sprockets

This assorted set of finished bore industrial roller chain sprockets is a versatile collection of precision-engineered components, designed to meet the varied power transmission needs of chain-driven mechanical systems. Each sprocket is optimized for reliable performance, straightforward installation, and long service life in industrial, agricultural, and mobile equipment applications.

Construction & Materials

Every sprocket in the set is manufactured from high-strength carbon steel, which undergoes a controlled heat-treatment process of quenching and tempering. This creates a hardened tooth surface (HRC 42–48) for exceptional wear resistance, paired with a tough, ductile core that can withstand impact loads and torsional stress. The precision-machined, smooth metallic finish on the bores and hubs ensures precise alignment and reduces friction, while the heat-treated teeth resist elongation and fatigue, ensuring a long service life even under continuous operation. The uncoated steel surface is optimized for compatibility with heavy lubrication, extending performance in dusty, high-load environments. Each sprocket is also marked with part numbers and specifications for easy identification and inventory management.

Design Features

Precision Finished Bore: The pre-machined, dimensionally accurate bore on each sprocket 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.

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.

Robust Hub Design: The integrated one-piece hub provides increased structural rigidity, distributing axial loads evenly and preventing premature fatigue. The varying hub diameters and tooth counts in the set offer flexibility for different torque requirements and chain sizes.

Performance & Applications

This assorted set of finished bore sprockets is ideal for maintenance, repair, and operations (MRO) stock, as well as for prototyping and custom system builds. They excel in 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, grain augers, and hay balers

Material handling systems and automated production lines

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.
