When a worn or undersized sprocket causes chain skipping, accelerated wear, or drivetrain misalignment, the fix starts with a correctly matched component. These #60 (12A) simplex roller chain sprockets are engineered for makers, machine builders, and industrial DIYers who need reliable power transmission without guesswork. Whether you're replacing a failed sprocket or speccing a new drive system, selecting the right tooth count is critical to chain engagement and longevity.
Each sprocket in this series is machined to ANSI #60 / ISO 12A standards with a 3/4" (19.05 mm) pitch. The stepped hub design provides a secure shaft seating surface and simplifies alignment during installation. Available in 10 through 30 teeth, the bore and hub dimensions scale with tooth count — refer to variant options for exact measurements per size.
Typical applications include conveyor drive systems requiring a #60 chain simplex sprocket replacement, agricultural equipment and go-kart drivetrain builds using 3/4 inch pitch roller chain sprockets, and custom power transmission rigs where a stepped hub sprocket for ANSI 60 chain ensures precise shaft positioning and reduced vibration.

The tooth count determines your drive ratio. Divide the driven sprocket teeth by the driver sprocket teeth to get the reduction ratio. For example, a 10T driver paired with a 30T driven sprocket gives a 3:1 reduction. Lower tooth counts on the driver increase torque; higher tooth counts increase speed. Select your Size variant above to match your target ratio.
No. This sprocket is designed exclusively for ANSI #60 / ISO 12A simplex (single-strand) roller chain with a 3/4" pitch. Duplex and triplex chains require multi-strand sprockets with wider hub profiles. Using this sprocket with duplex chain will result in misalignment and accelerated wear.
A stepped hub means the sprocket bore transitions through one or more diameter steps rather than being a straight-through bore. This creates a positive shoulder that the shaft seats against, providing accurate axial positioning without requiring a separate spacer or collar. It simplifies installation and helps maintain consistent chain alignment.
The bore diameter varies by tooth count. Please refer to the specific variant's detail page or contact us to confirm the bore dimension for your selected size before ordering. Measure your shaft diameter with calipers and compare against the listed bore. A standard keyway or set-screw arrangement is typically used to secure the sprocket to the shaft.
Material and surface finish details are listed per variant — please check the variant options or contact us to confirm. For outdoor or high-moisture environments, we recommend verifying the finish specification and considering a compatible chain lubricant to extend service life regardless of material.
Yes, in most cases. These sprockets conform to ANSI B29.1 tooth geometry for #60 simplex chain, making them dimensionally compatible with OEM sprockets of the same tooth count and pitch. Always verify the bore diameter, hub length, and overall width match your application's requirements before installation.
Load and speed ratings depend on the specific tooth count, material, and your chain's rated working load. As a general guideline, ANSI #60 chain has a rated breaking strength of approximately 8,500 lbf (37.8 kN). For precise load capacity data for your selected variant, contact us to confirm — we recommend staying within 25% of the chain's rated working load for continuous-duty applications.
