How do I know what size drive chain I need?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
How do I choose a chain sprocket size?
Determine the number of teeth of the small sprocket. The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is recommended. The number of teeth on the large sprocket should be less than 120.
How much slack should a drive chain have?
For normal drives, adequate slack should be adjusted to 4% of the chain span. [Example, if the chain span is 46.5″, slack should be 46.5″ x 0.04 = 1.86″] (C).
How do you calculate the capacity of a chain conveyor?
2) To calculate the driving power (CV or HP), use the following formulas: N = T x v (m/s) = (metric) and T x v (fpm) = (imperial). 75 33000 Page 7 www.PDHcenter.org PDHonline Course M416 www.PDHonline.com ©2012 Jurandir Primo Page 7 of 10 4.
How much chain slack is too much?
Push up on the bottom of the chain and note the distance between the full-slack (lower) position and the no-slack (upper) position on the bottom . 1.2–1.6 inches (30–40 mm) is typical for streetbikes, while dirt bikes may need 1.4–2.0 inches (35–50 mm) of slack.
How do you calculate chain?
Procedure
- Calculate C, where C = CD/p.
- Calculate A, where A = Z1 + Z2.
- Calculate S, where S = Z2 – Z1.
- Refer to the adjacent table to find the T value for the calculated S value.
- Chain Length in Pitches, CL = 2C + (A/2) + (T/C)
How do you calculate the load capacity of a conveyor?
CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)
How long is a Gunter’s chain?
66′
The chain was used by American surveyors from the colonial period through the early 20th century. A Gunter’s chain is 66′ (4 poles) long and is made up of one hundred links, connected by two rings. A brass tally or tag marks every ten links. A link in measurement includes a ring at each end and is 7.92” long.
What size is 35 chain?
#35 Chain Dimensions

| 35-3 | 0.375″ | 0.70 LBS |
| 35-4 | 0.375″ | 0.95 LBS |
How tight should my chain be?
Is it coming undone while you ride? Check your chain out. It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up.
