39 Tooth HTD Plastic Pulley Kit

The bore on these pulleys will not accept 1.125' bearings as advertised. We measured them at 0.95' which is a bit too large for 7/8'. This renders them unsuitable as idler pulleys unless you add hubs and externally supported bearings. We've ended up printing pulleys with the correct bearing carveouts to keep us moving. That plus shipping delays to get the parts left us disappointed with Andymark.

[AndyMark reply: Please see the pdf layout print displayed on this product page. The intent for this product is to be driven by a hub, not rotated on a bearing.]
