Hi performance Single belt AK30 with 15mm bore and 5 mm key.
Sheave Pulley fits 1/2" wide belts such as US size A, 4L, & 3L belts.
Tired of getting AK30 sheaves that have 0.030" or worse run out?
Sheaves that shake and wobbel? We are as we were throwing 1 out of every 3 that we
purchased new strait from the box and into the trash can.
Ours run 0.0005" to 0.006". This runout is actually due to how you fit the pulley to your
motor. If you fit it correctly expect less than 0.002"
Made out of aluminum and with less than 0.006" run out.
That enabels these to run as fast as 6,500 rpms and no vibration.
Make note:
These are built for lathes and mills where the pulley is inside a housing.
They are cut out of solid aluminum to keep the weight low and the accuracy high.
These are not suited for your lawn mower or any location where rocks or other opjects
could be thrown against them. For that go buy a cheap cast iron pulley.
