If this is not the rubber track or machine you want to fit,please message me with your excavator brand and model.
ΔHow to Measure Rubber Tracks?
To check for the size of your existing rubber track you will need to measure followings:
1. Measure the width of the track in millimeters or we can do the conversions for you. (1 inch = 25.4 millimeters)
2. Measure the distance from the top of the center of one link (metal piece that engages with the sprocket on the track) to the top of the center of the next link (in millimeters or we can do the conversions for you). This distance is known as the pitch of the track.
3. Count the total number of links(also called metal pieces or lugs) inside of the track in one row.
So the measurement of a track is Width x Pitch x Links.
ΔInterchangeable Track Designs
Interchangeable guide type replacement tracks were originally designed for use on equipment with undercarriages designed for steel tracks but now most can interchange with rubber. Interchangeable type rubber tracks have pitch measurements (this is the distance from the center of one metal link to the center of the next metal link) of 47, 48, 48.5, 60, 52.5, 53, 54, 54.5, 55, 55.5, 56, 71, 72, 72.5, 73.5,74,75.5, 76,79, 81,81.5, 83.5, 86,88,90,92, 96, 100,101,101.6,106,107,108,109,110,125,142,144,150,152.4,225millimeters.
ΔConventional Track Designs
Conventional guide type replacement tracks are designed for use on equipment with undercarriages designed for rubber tracks. Conventional type tracks have pitch measurements (this is the distance from the center of one metal link to the center of the next metal link) of 29-114,or more,that can be customized.
