Component tests

Test Description Target Tolerance
Length Measure the length of the belt using a measuring tape. See BOM spec. +/- 1cm
Width Measure the width of the belt using digital calipers. 5.8mm +/- 0.2mm
Extrusion fit Lay the belt into the V-slot of an extrusion. The belt should pass through the narrowest section and lay flat in the bottom of the slot. N/A
Pitch Measure the distance between one tooth and another one 50 teeth away using digital calipers, then divide by 50. 2mm +/- 0.02mm (1%)
Pulley fit Engage the belt to a GT2 pulley. The belt should fully engage with the pulley’s teeth. N/A
Thickness Measure the thickness of the belt using digital calipers. 1.25mm +/- 0.1mm
Belt sleeve fit Assemble the belt to a belt clip and secure with a belt sleeve. The belt sleeve should fit snugly over the two belt sections and provide adequate holding force. N/A
Stretch Tie a belt to a fixture 1.5m or more off the ground. Mark the belt just below the knot and then add a second mark exactly 1000mm below the first. Hang a 10kg weight from the belt (below the 1000mm mark) and measure the distance between the two marks. 1000m + 10mm (1%)
Strength Use a tensile testing machine to measure the equivalent hung weight at which the belt will break. 100kg - 20kg
Color Inspect the belt for any discoloration or markings Black, no markings. N/A
