If an offset section is required, it will be necessary to increase the width of the chain by 25% to account for the reduced tensile strength of the offset. Assembled products Chain can be delivered at the length the customer desires. Refile cutters using lighter strokes with the file held level or at a slighter angle, no. The total chain width is a variable depending on the thickness of the sideplates and if the chain has O-rings or X-rings. The working load sets a lower limit on pitch, and the speed sets an upper limit. Sharpen cutters on one side of the chain first. If an offset section is required, it will be necessary to increase the width of the chain by 25% to account for the reduced tensile strength of the offset. The drive sprocket and bar nose sprocket are teamed with the chain, and must be the same size or pitch. From this, determine the roller chain size and number of teeth for the driver sprocket. If it is 1/8th on the chain then you can measure your teeth and have a loook-see if they are that wide too.
