To convert idler pulleys to drive pulleys see Drive Pulley Adapters.
Stand-off from outer edge of idler = Stand-off - (Width of idler - 0.472")/2
Example: Stand-off from outer edge of Idler 3/8" x 3"
with shoulder adapter SA3827 = 0.27" - (0.65" - 0.472")/2 = 0.18"
Stand-off from center of idler = Stand-off + 0.236"
Example: Stand-off from center of Idler 3/8" x 3"
with shoulder adapter SA3827 = 0.27" + .236" = 0.506"
6203 bearing dimensions:
40 mm (1.575") OD, 12 mm (0.472") thick, 17 mm (0.669") bore.
