HTD 5M Belt Length Calculator

Planning a pulley swap? Enter your current setup and compare replacement pulley options to estimate the belt length and center distance.

1 Current Belt Setup Required

Not sure about your current belt length? Check the markings printed on your existing belt. Enter the belt’s pitch length, not its outside circumference.

If your motor mount or bracket has a printed adjustment range, enter the minimum and maximum center distances here. When both are provided, each result also shows the suggested belt length range for that mount range. If you leave these fields blank, the calculator estimates the required center distance from your current setup and does not show a belt length range or perform a mount-range check.

2 Replacement Pulley Options Up to 4 configurations

3 Calculation Results

Enter your current belt setup and at least one replacement pulley tooth count, then select Calculate Belt Length.

This is a calculator reference list only. It does not confirm LINNPOWER stock, availability, or compatibility with a specific board. Please confirm the exact belt specification with LINNPOWER before ordering.

This calculator provides theoretical estimates for reference only. It uses an approximate open-belt pitch-length formula and does not account for every pulley, belt, or mounting detail. Actual fit can vary with belt tension, pulley dimensions, motor mount geometry, and manufacturing tolerances. For Linnpower boards, please feel free to confirm the calculation and fitment with the actual hardware and LINNPOWER before ordering as we have access to your board's original specifications. The standard length list is a reference only and does not guarantee stock or availability.
