Common compatible belt widths include 9 mm, 15 mm, 20 mm, and 25 mm.

The aluminum alloy construction provides a good strength-to-weight ratio suitable for CNC router axis drives, 3D printer motion systems, and light-duty robotic applications. The HTD tooth profile distributes load across multiple teeth simultaneously, reducing stress concentration compared to trapezoidal (MXL\/T-type) profiles. For heavy industrial loads exceeding the rated belt tension, consult the belt manufacturer's load tables.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the AF-type bore require a keyway or additional machining?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo keyway is required. The AF-type design uses a radial set-screw to clamp directly onto a smooth shaft. If your shaft has a flat (D-cut) or keyway, the set-screw will engage it for even more positive retention. No additional machining is needed for standard smooth-shaft installations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill this pulley work with non-HTD 5M belts, such as GT2 or T5 profiles?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. This pulley is designed specifically for the HTD 5M tooth profile.
